CCTV analytics perimeter security solution. It WORKS!

Posted on by

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

IPCCTV over WIFI

The scenario.

Picture the scene (pardon the CCTV pun!)

Building A is 500 metres from building B

There are 4 cameras on building A, one on each corner (don’t you just love perfect worlds!) and they need to be viewed, recorded and controlled (did I mention they were PTZ?) all from building B

THE PROBLEM

The two buildings are separated by a river – a very nice river, big boats coming up and down, delivering stuff to dockside delivery points.

No chance of cabling then….. Until recently, the answer was to use free range wireless transmission solutions, such as RF, Microwave, Laser etc……… but, history shows that each has it’s positives and negatives but they all share one common negative….. expense.

ANOTHER WAY?

With the upsurge in IP, there is another way………..Wifi…………ok, professional wireless is what all the proper ‘wifi’ consultants will call it, but wifi nonetheless.

You see, Wifi does not have to be a one to one transmission solution…………. with typical bandwidth of 54Mbps, even if we halve it (because clever network guys will tell you that there is always a drop over distance etc), we can expect a 27Mbps bandwidth allowance……

So, take our building A and B scenario…. cable all the 4 cameras to a central point (it is a perfect world after all !) and either convert to IP from analogue using encoders (or, if we are to get this industry into the 21st century let’s push the boat out and go true IP cameras!) and connect to a regular 4 port network switch…

Take the output of that switch and insert into something like the Silvernet product range….. 1Km line of sight, pre-configured to create a point to point connection…..go to building B, position the receiving unit line of sight to building A and either decode back to analogue or bring one, neat, simple CAT5/6 cable out and introduce to the network for full control and view of the system ! simples !

THE THEORY AND THE PRACTICE

Ok, we don’t always have a perfect world, clearly, however, using the above solution, we have sent 4 cameras over the one link….saving a LOT of money:-

RF/Microwave/Laser = at least £2000+ for EACH camera

WIFI = under £1000 for a 1Km link with the ability to run a good few cameras – typically a PTZ IP camera would be around 5Mbs and a static at around 2Mbs

But, just like RF/Microwave/Laser, if the Wifi states ‘Line of Sight’ or LoS, then it REALLY means that…..so much as a leaf on a overhanging tree, or, in the case of our River separating the two buildings, boats that might momentarily ‘interrupt’ the signal, it is imperative to ensure that the TX and RX units are positioned so as to enjoy clear and uninterrupted transmission!

The cost savings are impressive and just might give this industry the excuse to use IP !!

IP camera news.Honeywell HD3MDIPX

 Honeywell latest news.

Honeywell have just announced that they are to add the HD3MDIPX HD mini dome to their extensive portfolio of IP camera products. The camera is accessible via the web with the usual anti tamper features. Honeywell’s latest IP mini-dome provides high quality pictures but comes at a price comparable to an analogue equivalent. The camera provides 720p and has a bandwidth that keeps the demands on the IT network low.

More news on this prouct soon.

Backbone integrated security solutions.

Backbone CCTV

Backbone security solutions provided by Backbone computer technology in Beijing China have their foundations in the research of video compression techniques, first developed as long ago as 1999.

Success.

Encouraged by their success, a year later they produced their first DVR range.This of course incorporated their their newly produced compression format and the collection of DVRs were called IDRS-2000 series. To compliment the DVRs and boost further sales they then designed and manufactured the SANNO camera range.

A brief history of their past leads us to their latest product. The IDRS 6000HC is now using H.264 and NVMS CCTV software. Complimented by many features it has plenty to offer.

The IDRS and Bernee brands form the basis of the Backbone product range which is supplied now worldwide and Backbone claim to produce very high quality products at a very competitive price. The collection of IP cameras and DVRs on offer certainly warrant a visit to their website.
