IP CCTV: What does pixel density mean exactly?

IN DEPTH An IP surveillance system may be used to observe and protect people, objects and people s activity inside and outside the objects, traffic and vehicles, money handling in banks, or games in casino environment. All of these objects of interest may have different clarity when displayed on a workstation screen. The image clarity depends primarily on the camera used, the imaging sensor, its lens and the distance from the object.

There is one parameter in IP CCTV that expresses the image clarity in a simple way with just one parameter: pixel density. The pixel density is usually expressed in pixels per metre (Pix/m), at the object plane, although it can be expressed in pixels per foot. Pixel density in IP CCTV sense should not be confused with the display pixel density quoted by various LCD display manufacturers which defines the screen density, in pixels per inch (PPI). The advantage of expressing object clarity with its pixel density is that it combines the sensor size, pixel count, focal length and distance to the object in just one parameter . When using pixel density metrics all variables are included and makes it universally understandable what details you will get on an operator s workstation screen. When designing a system, or a tender for a system, one can request pixel density for a particular image quality. So, instead of asking for a 6 mm lens for your camera in a particular location, for example (which means nothing without knowing the camera sensor it is used on), it would be much more useful if a particular pixel density is defined for the view. This will then be used to calculate the required lens for the particular camera used and the distance from the object. This will guarantee the clarity of the image (assuming the lens is focused optimally and there is sufficient light, of course).

Pixel density can be used for any object that IP CCTV user might be interested in: face, licence plate, playing card, money and similar. Let us now explore how many pixels per metre are attributed to various objects. One of the most commonly referred pixel densities is for Face Identification. Face Identification in CCTV means sufficient clarity of the image so that one can positively identify who the person on the screen is. According to Australian Standards AS4806.2, for Face Identification in analogue CCTV, we require 100% person s height to fit on the monitor screen display. The details of 100% person s height on a screen have been tested many times and it s been verified that they are sufficient for such a person to be identified. We know that PAL signal is composed of 576 active TV lines, so, according to AS4806.2, a person s height would occupy all of the active lines to make it 100%. Head occupies around 15% of a person s height, which is equivalent to around 86 lines (576 x 0.15 = 86.4), which is the same when converted to pixels (assuming recording is made full TV frame mode, which is equal to two TV fields). If we agree that an average person height is 170 cm, the head would occupy around 25 cm of that.

The pixel density at the object, which is required to make a positive Face Identification according to AS 4806.2, can be calculated to be 86 pixels at 25 cm of head height. Since there are 4 times 25 cm in 1 m of height, this becomes 4 x 86 = 344 pix/m. So, one can say that with pixel density of 344 pix/m at the objects plane it should be possible to positively identify a face, according to AS4806.2. Face Identification as per AS4806.2 Some other standards may require different values, and one such (newer) standard is the IEC 62676-4, which defines 250 pix/m to be sufficient (i.e. suggests that with slightly lesser pixel density than the AS standards one should be able to identify a person). Clearly, this number is not fixed in concrete, and it will depend on the observing ability of the operator, as well as other parameters (lens quality, illumination, compression artefacts, etc ), but the key is to understand that such a pixel density can be calculated for any type of camera, irrespective if that is SD, HD, 4k or any other format. The next image quality down, as defined by the standards is for Face Recognition. The details of Face Recognition image should be sufficient to recognise the gender of a person, what he/she is wearing and possibly make an assertion of who that person might be, if picked from a bunch of people that have already been identified somewhere else (e.g. passport or drivers licence photo).

This is basically an image with half the pixel density to the face identification, which according to AS4806.2 should be around 172 pix/m, while IEC62676-4 suggests 125 pix/m. Similarly, pixel density can be defined for vehicle licence plates visual recognition (not software automatic LPR). In the AS 4806.2, this is defined as 5% characters height on a display screen, which is around 30 TV lines (pixels) (to be very accurate 576 x 0.05 = 28.8). If we assume that a typical Australian number plate has characters of around 90 mm in height, than this equates to 11 x 30 pixels = 330 pix/m. The number 11 is obtained from dividing 1000 mm (1 m) with 90 mm. One may say that for visual licence plates recognition similar pixel density is required as for face identification. Licence plate recognition as per AS4806.2 When money and playing cards are observed in banks or casinos, many practical tests have shown that at least 50 pixels are required across the notes or cards longer side in order to positively identify the values. Standard playing cards dimensions are B8 according to ISO216 standard, which is 62 mm x 88 mm. So, we need the 88 mm card length to be covered with at least 50 pixels for proper identification.

This means around 550 pix/m (1000 mm / 88 mm = 11 => 50 pix x 11 = 550 pix/m) should be sufficient for playing cards. We may require slightly better pixel density for identifying money, since notes size is typically larger than playing cards, so if one takes the Face Inspection pixels density of 1000 pix/m, it should attain pretty good identification, although as it can be seen from the real life example below, even 770 pix/m might be sufficient. Playing cards and money shown above with 770 pix/m As it can be concluded from the above examples, the pixel density can be defined for any object and any camera, large or small. The beauty of the pixel density parameter is, as said at the very beginning, that includes all parameters influencing the clarity of the observed objects. For this reason, ViDi Labs has developed the ViDiLabs iOS calc (search the iTunes App Store under ViDiLabs calc ), a unique tool for the surveillance industry, which can also be used in cinematography, photography and any other imaging application dealing with objects details. So the following table can be used as a rough guide for various pixel densities.

How 360 cameras are a hit in casinos and why Oncam is relishing its Milestone partnership

Oncam is a leader in 360-degree network cameras and recently launched a 360-degree dewarping preview tool and a visualisation tool to give users a way of virtually sampling its signature innovations. To find out more about the company s latest products and strategy for growth, we spoke to Simon Reed, regional sales director for EMEA at Oncam. IFSEC Global: Hi, Simon.

So how did IFSEC 2017 go? Simon Reed: It was a super busy show for us. We were, for the first time, exhibiting in the main hall, as one of the partners featured on the Milestone Systems stand. Over the course of three days we did 70 presentations to individual companies, so we felt we had a really good response from the people coming to the booth and hearing about our technology and vertical market offerings. An Oncam 360-degree camera can cover an entire gaming table up close or several gaming tables while still maintaining picture quality and retention rates While retail is one of our strongest vertical applications, we have made significant strides within the casino and gaming industry, as well as hospitality, transportation and manufacturing. So overall, the show was good for us as a brand and a team. IG: Interesting that you have a strong present in gaming and manufacturing; they must have quite specific requirements? SR: Yes, they typically do and this applies to the global market. There are stringent regulations in place that have to be met when implementing security technology, such as video surveillance cameras, and the 360-degree camera we produce does lend itself well to the environment.

An Oncam 360-degree camera can cover an entire gaming table up close or several gaming tables in an area while still maintaining picture quality and retention rates. Within a manufacturing environment, larger areas can be monitored with fewer cameras which isn t the same with fixed and pan-tilt-zoom cameras that only cover specific focused areas. Additionally, the day-to-day mechanisms in use within the plant can be seen using the advanced picture quality found in Oncam cameras, so security managers can be made aware if people are putting foreign objects into food being processed, for example; so the development of this camera has been a big win for us in these applications. embedded content IG: Did you launch any new products at the show? SR: While we didn t launch new products, we did demonstrate a rewritten version of our software development kit (SDK) as it works with products from Milestone Systems. As they released their upgraded version of their product line, we delivered our updated SDK, ensuring that our products integrate seamlessly with one another for customers. As a result, we re able to speak with Milestone customers about our technology, and they are able to recommend panoramic cameras like ours to their customers. Over the last year, we introduced our new Evolution Stainless Steel camera in both 5MP and 12MP solutions, which has opened up a world of possibility within the pharmaceuticals, food processing, industrial/chemical plants, ports and marine industries. It was specifically designed to meet the needs of customers operating in more extreme environments, with special attention to ensuring the casing is resistant to corrosion from power washing and extreme heat/cold.

NSF International recently certified the camera in the United States with the NSF mark for food service, and it s the first video surveillance camera to have such a distinction. It also boasts IP69K/IK10 ratings, which make the enclosure resistant to high-pressure water jets, dust and vandalism. It s a very unique offering with multiple uses across applications. IG: What s the company s strategy? Where are the most auspicious areas for growth? SR: As we continue to grow and add more technology to our portfolio, there are several vertical market applications that are natural fits for our technology. We have a strong client base in retail, and anticipate adding to that in the coming years, while adding significant presence in the hospitality sector, such as on cruise ships and hotels/resorts. These facilities with their wide-open expanses are ideal for the 360-degree technology we offer. We will also continue to grow within the casinos and gaming market.

Ethernet over coax too often overlooked as a cost-effective migration path to IP, says AMG Systems

IP surveillance Organisations deterred from migrating to IP CCTV from analogue systems on cost grounds should consider leveraging existing coaxial cable, according to AMG Systems. The proportion of surveillance systems that are IP-based has been growing steadily for many years. However, our IDIS-sponsored Video surveillance report 2017 revealed that 21% of installed systems are still analogue-based and sales of analogue cameras still continue in surprisingly reasonable numbers.

AMG Systems is a UK-based manufacturer of edge-of-network transmission, including fibre, analogue, IP/ethernet, wireless and hybrid communication solutions. Ian Creary, AMG sales and technical support manager, says the reluctance to upgrade for cost reasons is understandable. They are worried that the migration to IP simply won t fit their budget, he says. And it can be a sizeable investment, particularly if you have previously poured resources into a substantial analogue cabling infrastructure. Labour requirements But Creary says that IP migrations need not be so expensive. There is a very large legacy install base of coaxial cable in existence, mainly related to analogue CCTV, and making use of this as a part of any analogue to IP system migration plan could certainly prove to be a cost-effective option, he explains. Without the requirement to install new cabling, labour requirements reduce dramatically. This can mean an ethernet over coax install can cost as little as 25% of the expense of a full IP upgrade. The advantages of an ethernet-over-coax solution are in the simplicity of its design and application: installation is easy and the data and images it provides are reliable, so everyone involved saves money.

Ethernet-over-coax products provide an easy-to-connect, transparent network that is very simple to use, reliable, and offers seamless integration between the existing coaxial cable and the ethernet backbone of the new system. Ian Creary, AMG sales and technical support manager Ethernet-over-coax products are invariably point-to-point: from a locally powered transceiver at the camera to a locally powered receiver at the control room. Adequate for smaller organisations, the point-to-point design needs strengthening where a large number of cameras are involved. A better solution for these larger systems that still want to benefit from utilising their existing analogue infrastructure is use a PoE switch, with four PoE ports and one coax uplink port at the camera, he says. This gives the user more leverage of their existing cabling system, and truly allows an easy and cost-effective upgrade to IP cameras. Ethernet cabling and devices powered over ethernet require the installation of additional networking products every 100 metres. This often means that power has to be sourced in locations that are difficult to access. This usually requires a lockable closet, cabinet or enclosure and units with power supplies inside, says Creary. Ethernet-over-coax devices, however, can be powered from a PoE switch, and deliver power over ethernet up to 300m.

There are no repeaters or other networking products required, so the distance issue is addressed without an impact on the project budget. Ethernet-over-coax should be as appealing to installers as it is to end users, suggests Creary. Ethernet-over-coax products provide an easy-to-connect, transparent network that is very simple to use, reliable, and offers seamless integration between the existing coaxial cable and the ethernet backbone of the new system. The solution itself can be a simple design, and application is even more straightforward. Importantly, the data carried over the EoC network is robust and reliable, allowing for the transmission of high quality images and other sensitive security content. Ethernet-over-coax technology will enable more installers to approach an IP migration project with a new set of financial and installation options. The end result is a high-performance system that saves all parties involved time, money, and concerns over flexibility and adaptability.

Qognify announces deeper integration with Bosch s suite of network cameras

Integration PSIM pioneer Qognify has expanded the integration of its Situator and VisionHub platforms with Bosch s network security cameras. Operators can control and manage Bosch cameras centrally through Situator, including PTZ and PTZ-like control for moving and fixed cameras, automatic triggering of processes when predefined incidents occur based on pre-defined alarm rules. These rules are based on video analytics built into the camera, playback via local camera storage and camera tampering detection.

The integration of Bosch s FLEXIDOME IP panoramic 7000 camera with Qognify VisionHub gives customers access to dewarping technology that eliminates fish eye lens distortion, provides 360 of view without blind spots, and an undistorted overview image. Customers can digitally pan, tilt and zoom to focus on details without sacrificing the bigger picture, says Qognify. A single device can accommodate wide coverage and achieve a normal view from an otherwise distorted or reversed image. Bosch intelligent dynamic noise reduction, meanwhile, optimises storage capacity and eases network load. Distinguishing between noise and relevant information, it only uses bandwidth when required and slashes the camera s bitrate by up to 50% and therefore the total cost of ownership. VisionHub also helps security departments avoid network overload during working hours thanks to the automated, scheduled transfer from camera on-board storage to the centre. It also restores missing video from the camera s on-board storage. Qognify s VisionHub integrates with the video analytics platform built-in to Bosch cameras. The integration also supports the central operation, on the recorder, of Qognify s video analytics suite.

Qognify says the combination of edge-based analytics (courtesy of Bosch) and server-based analytics (from Qognify) gives designers of CCTV solutions maximum flexibility. When mission-critical solutions are involved, it is essential that stringent quality checks are taken. Qognify s solutions were tested to excel in multiple integrations, said Rudolf Spielberger, head of the integration partner program at Bosch Security Systems. Our strategic cooperation with Qognify is substantially enhancing the levels of security and delivering clear and quantifiable business advantages to our customers. Eran Noam, VP of global strategic partnerships of Qognify, said: We are committed to advancing integration with leading technology partners and are proud of our integration with Bosch to yield a complete, tested and field-proven solution. It s important that organizations have confidence in integrations so they can leverage the broad range of excellent, integrated products in today s security marketplace.

Magnetically-driven PTZ cameras and bespoke camera housing: Redvision rejects one-size-fits-all ethos of CCTV market

Paul Hucker, founder, Redvision Redvision recently unveiled two innovations that it believes distinguishes itself in a market characterised by homogeneity and a misguided emphasis on driving down the price of hardware. Unveiled to a select audience of customers and contacts the Volant is a PTZ camera that Redvision says moves faster, more accurately and more quietly than anything else on the market. Vega, meanwhile, means integrators can offer clients the chance to customise camera housing to meet their aesthetic needs.

IFSEC Global caught up with the company s founder and director, Paul Hucker, and MD, Dermot Grace, to find out how the company is positioning itself in the surveillance market and its plans for IFSEC. The Volant and Vega ranges will be launched officially at IFSEC International 2017 between 20-22 June. You can find Redvision on stand D1150. Get your free badge now. IFSEC Global: Hi, Paul. Hi, Dermot. Where do you sit in what is a crowded CCTV market? And what are your USPs? Dermot Grace: Redvision is one of the pioneers of the rugged PTZ Pan, Tilt, Zoom marketplace.

There are probably three or four major manufacturers worldwide and we would probably command a substantial market, certainly within the UK market. Our routes to market have historically largely been through our distribution partners, which we re looking to develop further within Continental Europe. IG: The next obvious question is about your new product launches Paul Hucker: We re at IFSEC to launch two new product ranges: Vega and Volant. Volant is the fastest, most Dermot Grace, MD, Redvision accurate, quietest PTZ on the planet. A PTZ used to move at 60 degrees per second but with the Volant it s now almost instantaneous: about 400 degrees per second. Volant will move to the exact position it needs to go to. If cameras respond quicker you stand a much better chance of getting evidential or dynamic information. Because the cost of installing a camera in a town centre is huge, people don t spend enough money on the cost of the equipment itself. Paul Hucker It also has infinity motors which can remember exactly where they were before.

PTZs have motors and gears and the gears add a degree of inaccuracy and a degree of wear. But the infinity motors are magnetically driven so the motor s resolution is huge compared to a geared system. It will register within 0.01 of a degree every time That means cameras can cover a larger area or a smaller area at distance more effectively. So it s very much for areas where they want the best in what technology can offer right now. With this camera range we have standard cameras and cameras with adaptive IR and adaptive white light. Adaptive means the actual beam angle of the illumination varies with the angle of the zoom lens. We have a number of high net worth customers who like the white light because it s a visual deterrent. Another feature of the Volant is it is completely silent. That s because it s moving by magnetic force.

We re the only company using infinity drive motors in a big PTZ. We ve taken something generally used in military and using it in a commercial application. While it s more expensive than the commodity products, the overall cost of ownership is low. Because the cost of installing a camera in a town centre is huge and people don t spend enough money on the cost of the equipment itself. The equipment is running continuously, and continuously moving, so it has a very high duty cycle. We ve had high demand already for a lot of public buildings to be monitored using a thermal version of the Volant. One reason is it s so much more accurate and better at analytics than other PTZs. You can apply analytics to it with certainty that you ll get the same picture every time. It s the equivalent of a static camera with up to 200 positions.

All we re trying to say is one size doesn t fit all. Driven by price, most CCTV players have come up with the same solution. Paul Hucker IG: The customised housing concept of the Vega range is an interesting innovation in a market where, frankly, one bullet camera looks very much like the next DG: One USP Redvision has as a business is its complete flexibility. We can come up with different paint finishes and it s surprising how many customers do need these specialisations. It could be colours. Bournemouth College had a particular colour. This was done within a week or so, so it s a very fast turnaround. PH: The Volant is a side-mount PTZ rather than a normal PTZ, which gives us flexibility to do custom options on the camera mechanism. For clients we can offer different lens options for thermals.

IG: To what extent do you think there s too much focus on the price of hardware? PH: I think it s a huge issue. We are potentially devaluing the overall marketplace by focusing on price rather than functionality. If you look at other sectors hi-fi systems or cars people go for premium brands for a reason. I m not saying there isn t room for budget brands, but at the moment we re in danger of devaluing the options. DG: So much so that installers are saying to us great, this is a different solution that I can take to my customers. They can differentiate themselves with their customers. It s pretty much solution selling. PH: All we re trying to say is one size doesn t fit all.

The Vega is a range of camera houses we ve launched because driven by price, most CCTV players have come up with the same solution. The cameras are getting smaller and smaller and less obtrusive, which is a good thing in some respects, but we feel cameras should have a bit of physical presence and be a bit tougher. We want to do several variants of the Vega housing to look more like street furniture. For example it can be colour coded on a public building. It s got things like a built-in windscreen wiper as it rains in the UK a lot. DG: And when it s in the parked position, you can t see it, it s out of the field of view. Also, within the camera housing we ve got the opportunity for PoE. PH: This is being launched at IFSEC as a concept with empty housing but we will add to it. We re creating an explosion-proof version.

Explosion-proof cameras generally have a stainless steel tube with stainless steel ends and one with a little window and it s not developed much over the past 20-30 years. DG: In fact, the number of ancillary equipment manufacturers has declined so there s little choice. The demand is out there. Paul always says let s say you want a camera in a BMW showroom they may want the camera housing in the BMW colours. Most manufacturers are only set up for mass production. But we ve got applications where we ve adapted our standard product for critical applications like the nuclear industry. Dermot Grace PH: Because it has very easy access into the camera housing you can do all your PoE or fibre convertor work in there. Anything that normally goes in the junction box, you can put in the housing. You don t need an ugly junction box on the wall, it s one less thing to install, and it s all integrated.

It s been designed so it can work both ways. Normally a camera housing has a top and a bottom. The Vega is symmetrical in look, so on a garage forecourt, for example, it could go under a canopy, you switch the bracket and it looks OK. It looks more aesthetically pleasing. IG: ?What kind of verticals do you particularly thrive, or hope to thrive, in? PH: Town centre application is our biggest single market. High net worth individuals and any CNI areas are important too. DG: If we take our existing X-Series domes, they re big in the utilities sector and in the remote deployable sector. The thermal market in general is growing quite substantially.

So we re challenging this product to sit across a wide spectrum of marketplaces. As well as traditional CCTV we re looking at military applications and other verticals we can move into. PH: Also it s more led by the quality integrators that actually want to keep some value in the project. They re selling the benefits of Redvision through their channels. You have to bear in mind we re a product manufacturer who doesn t sell products directly to the end user although we do show the end user. It s not always easy to work out the exact routes. We ve lost more of the smaller installers to lower cost kit. But the larger integrator, the likes of ADT, Quadrant can see the benefits of Redvision. DG: Whenever we ve shown this product to a customer in a pre-launch meeting they ve said wow, that looks really nice.

The same will apply to the camera housing. Even the ATEX housing is designed differently. Ease of use will be far better than what exists out there and it will be competitively priced because of the way it s been engineered. PH: In short, we ll be exploring more verticals because our ambition is to get to a 10m company in the next three years. Now we re a 3m company so we have to find niches for that. We re not going after the mass market. IG: What about distribution? DG: We ve signed an agreement with industry professionals representing five brands to represent Redvision throughout Scandinavia, central Europe and Southern Europe. They will use IFSEC as the launch platform.

Unlike many large companies, you can phone us and talk to someone. Paul Hucker IG: What are your thoughts on the future of CCTV? PH: We think use of thermal imaging will become four times as common over the next five years and we think the price will halve. So there will be price pressure but not to the same degree as other markets. We certainly see within five years that a third of our business or more will be on that product. We also see ourselves getting involved in other niche verticals and promoting the cosmetic side of CCTV. IG: Is there a benefit in being British? PH: We re more in touch with the needs of the UK market. There are several unique features resulting from our contact with the UK market.

DG: Most manufacturers are only set up for mass production. But we ve got applications where we ve adapted our standard product for critical applications like the nuclear industry. So that s how we d differentiate ourselves from a high volume manufacturer: total flexibility. IG: Do customers want the ability to customise? DG: Certainly. I think the fundamental thing is it s the voice of the customer that we re listening to. We reposition our products based on that. We also focus on customer service. Our turnaround time on any return is a maximum of 72 hours on receipt, 48 hours of those are on test.

PH: We ve had reports that some of our competitors take three months. These investments are long term and customers want to know they have good back-up for 5-10 years. DG: Our lead time to most distributors is seven working days. PH: The other thing is, three of our guys are on tech support. Unlike many large companies, you can phone us and talk to someone. If you have an issue onsite and normally it s install related rather than product related we are there 9-5, Monday to Friday. DG: We also have people who can attend site. Sometimes a problem has nothing to do with the product; it might be the VMS software controlling it. We have people in the north and south.

In our offices we have hot desks, so if someone phones in about an Avigilon platform, we can put that into the desktop and bring it up. So we can quickly replicate what they re talking about and talk them through what they need to do. PH: We can either do key by key or take over the set up if we need to. DG: We can accommodate most commonly used platforms, from 20 or so manufacturers. We recently had an event at our factory and people were taken aback with our flexibility and support. PH: It s an expensive resource for us to run but it s a big security net for the customer. DG: We re the industry s safe pair of hands. IG: So what are your hopes and expectations for IFSEC 2017? DG: At IFSEC we would like the opportunity to talk to distributors and integrators across the world because there s no limit to what we can t do.

PH: And now we have a network of people across Europe who can support those contracts. We work with BSC Europe. One of our biggest problems previously with IFSEC is we ve not been well equipped to follow up leads outside the UK. But now we have the network to follow those up. DG: We re always open to talk to people about any new products they want. Should there be a custom requirement for another partner, we d look into that.

This was the theme of an interview conducted with Jonas Bergstr m, business development manager at Securitas, by Axis Communications, which is a major partner of the manned guarding giant. Securitas regularly installs thermal cameras from Axis.

Axis Communications: What is the single greatest advantage of thermal cameras compared to optical cameras? Jonas Bergstr m: The absolute greatest advantage for us is that thermal cameras result in significantly fewer false alarms. This means our operators in the security operation center do not need to evaluate as many incoming alarm calls and therefore become significantly more time-efficient. For what installation scenarios are the thermal camera models most suited? JB: We primarily use thermal cameras in perimeter protection installations. An intelligent video application is integrated into the cameras and forms a virtual fence. If anybody or anything crosses this virtual line then an alarm call is sent to our security operation center (SOC). What have thermal cameras contributed in terms of savings for Securitas with the reduced number of alarm calls? JB: Securitas always aims to minimise the number of false alarms.

A minimum number of false alarms means that the operators can be more efficient when authentic alarm calls come in. In extreme cases, too many false alarms can affect an operator s attention and ability to identify authentic alarm calls. We estimate that the ratio of false alarms generated by intelligent video analysis in a thermal camera in relation to an optical camera is approximately 1 in 10. By keeping down the number of alarm calls per camera, each operator can handle more alarm events within a certain time frame. The result is major savings. embedded content Do you have an example of an installation where thermal cameras have been of great benefit and resulted in different types of savings for both the end customer and yourselves? JB: For a very large number of our customers, the implementation of thermal cameras, with intelligent video analysis connected to our security operation center (SOC), has resulted in major savings. The result has been reduced vandalism, interrupted and halted burglary attempts, reduced number of emergency call-outs from security guards and reduced use of operator time. AC: Why have you chosen to only use thermal cameras for perimeter monitoring?

JB: The number of alarm calls generated is significantly lower than when using optical cameras. Thermal cameras do not need extra lighting to be installed. Thermal cameras are not as sensitive to different weather conditions, such as snow, rain, fog, etc. We can cover a larger area with a smaller number of cameras. With thermal cameras we can detect movement in areas of vegetation. In this environment we would have greater difficulty in creating enough contrast in the image to generate an alarm. AC: At what distance from the camera can you detect people with a high degree of certainty? JB: It all depends on the camera model used, with regard to the focal length of the lens. At up to 200 meters, it is normally no problem to detect and generate an alarm for people or objects moving in the image.

AC: Based on your experience, are there any weather conditions that are particularly tough for thermal cameras? JB: Dense fog, very heavy snowfall and certain reflections from puddles of water may cause problems, even for a thermal camera. Our experience is that thermal cameras work considerably better than optical cameras in unfavorable weather conditions. AC: Are there any other conditions that make things difficult for thermal cameras? JB: Yes, vibration caused by an unstable mounting surface or a wind-sensitive mast is always a problem when working with alarms triggered based on intelligent video analysis. This primarily applies to long distances, because here even small vibration has a significant effect on the camera. However, Axis thermal cameras have built-in electronic image stabilisation (EIS) that helps in these conditions. You may also encounter problems even when the surroundings or backgrounds are the same temperature as an object in the image. This happens because a thermal camera cannot distinguish an object from its surroundings.

Exactly as with optical cameras, its surrounding environment affects the thermal camera. In general, the point is that a thermal camera is less affected by external factors than an optical camera.

CES 2017 sneak peak: the light bulb with a hidden security camera

CES 2017 Sneak Peak: The Light Bulb With A Hidden Security Camera

Light bulb maker Bell & Wyson is set to unveil a light bulb with a concealed camera embedded at CES 2017. The low energy (11W) LED bulb-cum-camera has a TF slot and two-way microphone and will stream footage to tablets and smartphones via Wi-Fi. The idea behind the innovation is that intruders, unaware of the light bulb s dual purpose, will neither seek to evade it gaze nor tear it from the wall/ceiling.

And of course, like traditional security lights, it could deter breaking and entering as it gives the impression that someone is home. Although this means an intruder can also easily turn it off though of course he probably won t even realise it s a camera anyway the device streaming app that accompanies the light bulb notifies a user every time the bulb is switched off and will record footage of the intruder beforehand and send the image to the owner. The camera can be managed remotely via a free iOS/Android app, which alerts the homeowner when movement is detected. Footage can be recorded on a Micro SD card (optional) all events. The bulb has a brightness output of 600 lm, equivalent of 60W. Lighting cycles are programmable. Stephane Burlon, a director at the France-based company, spoke to BBC News in advance of CES 2017 about the product.

Quizzed about whether such products would make homeowners uneasy about being under the gaze of a camera, he pointed out that when you switch the light bulb off, you switch the camera off too, so it s always clear when the camera is on or off.

Mobotix profile: the decentralised security camera and software specialist

Mobotix Profile: The  Decentralised  Security Camera And Software Specialist

If you work in the video surveillance and security sector, chances are you ll be familiar with the name Mobotix. Now in its second decade, the German IP camera and software specialists has made a name for itself developing the first decentralised IP camera and supplying the Mount Everest webcam. Contrary to popular perception as a hardware provider, the company sees itself as a software specialist with in-house hardware development of digital, high-resolution and network-based video security.

It produces complete systems using a single source. The company claims to be ranked fifth worldwide for video security (second within Europe, Middle-East and Africa) and to be world leader for megapixel surveillance cameras. The world s first decentralised IP camera The publicly traded firm with headquarters in Langmeil, Germany, is known for its network camera technology. The company was founded in 1999 and in the same year released the industry s first decentralised IP camera. Its Linux system contained video, alarm, and recording management functions in one unit, thus doing away with the need for licensed video management software to handle the recording event. Since then, the decentralised concept has been further developed to make high-resolution video systems more cost-efficient as the cameras themselves execute video analysis and event detection internally, and manage their video ring buffer on a NAS or server by themselves. This is said to reduce the workload of the VMS workstation and network considerably. Network ‘uctuation or longer interruptions are compensated by an onboard video buffer SD card. As a result, Mobotix video systems are claimed to be reliable while needing fewer servers and workstations, and less network infrastructure than other brands.

The company says this reduces the overall system cost as well as power consumption. Encrypted recording by the camera itself is claimed to guarantee data security and privacy. Of similar ilk is the company s M12-type model that serves as the world s highest webcam on Mount Everest. Powered by solar cells and operating from 6am to 6pm local time, it s capable of operating at temperatures as low as ’30 C and broadcasts live high definition video worldwide via the Internet. Located at an altitude of 8,000 meters, it works in conjunction with the Everest weather station to provide scientists with details of climate change. Event-driven ring buffers and onboard encryption Thus optimised for remote applications and cloud-based technology, the company s systems seem to be capable of reducing video bandwidth by scaling size and frame rate. Image detail is preserved via onboard Virtual PTZ functionality which stores high-resolution video in-camera and delivers low-bandwidth live images and playback on demand. In addition, Mobotix cameras are said to be able to manage an event-driven video ring buffer via a network or the Internet. Live and recorded video can be secured via in-camera video encryption.

Since 2010, Mobotix has extended its product range to include intelligent home automation. From the first autonomous IP cameras released at the beginning of the millennium, systems have been equipped with CMOS sensors without any moving parts, said to improve backlight recording and long term reliability. Two-way audio with VoIP messaging and phone connectivity using the SIP standard is included alongside weatherproofing and IP66 protection. In 2015, a new range of competitive 6-megapixel indoor cameras for ‘exible ceiling and wall-mount installations was launched. A fish eye lens on the hemispherical device is said to be capable of covering an entire room without any blind spots while the company s Moonlight Sensor Technology is claimed to be light sensitive enough to produce high-quality videos without motion blur even in low-light conditions. embedded content Optics, motion analysis and object statistics Other industry staples the company specialises in are interchangeable lenses, motion analysis and object statistics. A change of optics can be performed by customers themselves for most models. Camera positions can be changed and the optics adjusted according to the new mounting location. As the choice of lens dramatically varies the scope of a camera, using a super-wide angle lens, for example, enables an entire room to be monitored from a corner.

In turn, telephoto systems can capture details at longer ranges such as a number plate or the facial characteristics of a person. High quality HD lenses are said to fit different Mobotix camera series, and are backwards compatible with older models, even though the area captured by the lens may slightly differ with the image sensor installed in the camera. Mobotix also offers motion analysis for its systems. Its MxActivity sensor is said to only record video or trigger alarms if an operationally important event occurs. Interference caused by moving trees, shadows, passing clouds or snowfall is ignored; automatic configuration means only the objects direction of movement needs to be selected. As for object statistics, the firm s cameras seem to be capable of a range of operations. By defining counting corridors in a shopping mall s camera feed, for example, shopper numbers can be determined over the course of a week. The camera records how often each counting corridor is crossed within a specified period. The reliability of the count depends on the similarity of the sizes and shapes of the persons or objects in the image, their relative distance, how effectively they can be visually distinguished from their background, and how close the counting corridor is to the centre of the image.
