CCTV analytics perimeter security solution. It WORKS!

CCTV video analytics.

Video analytics has been a technology that has been talked about for a long time but at last it has  now finally arrived in a format that works reliably and achieves the results that will make customers keen to upgrade their legacy CCTV systems.

CCTV Alarms.

Used to alert the end user of an unusual event or an intrusion into a protected area it helps to give security managers a better insight to events and alarms occurring on their site. There are many types of events that can be raised to his attention and these include.

People counting

Speed monitoring

Facial detection

Loitering

Perimeter protection

Fall detection

Queue length monitoring

Panic alarm

Object abandonment.

And more to boot.

Advanced CCTV software.

Video analytics works by using advanced software to detect in real time changes within the view of the camera, far more advanced than motion detection, all analogue cameras currently in use in the UK can be converted to use this technology. It’s a simple process just install a unit called a codec. The codec is attached to the camera and behind the scenes converts all the video into a format that analyses events and through a set of clean contacts an alarm can be raised in a variety of different ways.

IP CCTV codec.

The codec is an IP device and is programmed through a laptop or if connected to a network it can be remotely administered. Xtralis, Bosch and March Networks all produce units that excel in video analytics.

CCTV Airport!

Examples of where analytics can be used to great effect include ports and airports combating threats of terrorism especially identifying abandoned objects, Protecting classic art using analytics means museums can also benefit from this feature.

CCTV perimeter protection.

Perimeter protection is another area that has seen far better security thanks to trip wire features and the ability to detect movement in a certain direction. Integrating analytics with FLIR thermal imaging cameras is an excellent example of how a sensitive area during hours of total darkness can suddenly be secured where before this would have been impossible.

Codecs.

Setting up the codec’s is a relatively simple task. Perspective is important to ensure only the objects or human movements are detected and things such as wildlife are totally ignored. A great advance for the industry analytics are now being incorporated directly into the heads of cameras and the Predator camera from 360 vision is the first 360 dome camera that can deal with analytics while on a tour something of a dream for security guards who are tasked with monitoring large establishments or estates.

CCTV investment.

As the investment goes heavily into this technology from the big manufactures we see the number of applications increasing and soon analytics will be commonplace in many businesses across the UK

External security perimeter protection IFSEC 2010.

External security solutions.

What solutions will we see at IFSEC this year with regard to external security protection? Integrated CCTV have lots of experience in both the advantages and the pitfalls of the different detection solutions. Below we list some of the options and when and where they should be used.

Perimeter protection.

External security  has been around now for many years now. Originally of course there was CCTV. At the time a fantastic deterrent. However as the criminal fraternity have become used to cameras and less fearful of the consequences of  CCTV evidence, the industry has had to concentrate on more effective ways of keeping criminals away from vulnerable sites.

Fixed beams or PIR sensors?

Both have their place, Pirs can of course be vulnerable to environmental problems such as flapping plastic , sunlight issues and wildlife. They can however be used in any position on the site and for blanket coverage are the best way to protect most external stock. Fixed beams are more reliable and stable but they rely on line of site between the transmitter and receiver and on many sites this just is not possible. Even where it is it tends to mean that the customer looses storage space and this rarely fits into line with his operational needs. Fixed beams are also overtly obvious and can be over-come on rare occasions because of this.

CCTV Analytics.

So are analytics the answer? This is a means where by using advanced video motion algorithms in conjunction with static CCTV cameras, security systems are able to generate an alarm condition . Human intrusion onto a premises can be detected with relative certainty. The drawbacks of this are generally related to lighting issues and of course the quality of the camera that has been installed. Most important is  the view we can get from that camera often we need lots of cameras if the premises is large or has lots of nooks and crannies, we then have the issue that too many cameras and the costs rise, too few and we leave vulnerable areas on the site. In addition if we have dynamic stock movements this means scenes can change and the  alarm point becomes irrelevant.

Flir thermal imaging cameras.

Thermal imaging cameras are definitely a brilliant way of confirming an intrusion. They can even detect heat behind walls or in sheds. they are the best way to be  100%  sure that there is human activity within a restricted area. The only real drawback is the cost but Flir the main player in the marketplace have some convincing arguments as why they should be used more and more for commercial security applications. Definitely worth looking into.

Deterrent.

Of course it is all very well detecting an intruder but what is the best way to encourage them to leave site and leave property untouched? Some use lighting or a verbal warning and activate local alarm sounders. This works very well at moving criminals on, no one wants to be caught, so drawing attention to an intrusion though noise is highly effective. Other methods include a central station response to a fixed beam activation , that is we send the signal through like we would on an intruder alarm alerting the central station that the perimeter has been breached.

Off site response.

CCTV monitoring by remote central stations is the main way that most businesses choose to protect their external stock. Once an on site alarm is generated this sent together with the CCTV image to the central station. The image is presented to an operator and if a person is seen a key-holder is called and mobilized to site , In addition the central station can tannoy the site and warn the intruder that they are being watched.

Monitored CCTV broadband connection.

In the past the CCTV images were always sent by PSTN or ISDN phone lines. Now with these being phased out under the BT21CN upgrades most companies now rely on broadband to transmit these images. This is where without serious thought remote monitoring can become unstuck. What if the broadband line goes down? Well Emizon21 IP have the solution to that problem .They are one of the few who can monitor broadband lines properly for failure and transmit an alert via a secondary signalling path to the central station to warn them of  any problems with the line.

IFSEC 2010

So external security has come a long way in the last 20 years and we look forward to what IFSEC 2010 has to offer us this year. We think IP cameras able to generate alarms with on board recording and switched relay contacts to activate sounders will be playing a part but can they replace traditional methods. We will have to wait and see.
