External security perimeter protection IFSEC 2010.

Posted on by

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.

FAQ about Redcare

Posted on by

Redcare Classic.

Redcare Classic was the first really secure form of monitoring introduced into the intruder alarm market. It worked by continuously monitoring the copper pair of wires that connected the alarm panel to the central monitoring station. A series of chirps could be heard on the line under certain conditions but in general it worked over the top of the speech so was inaudible to the phone users. Redcare claim it could not be defeated and to be fair we at Integrated CCTV have never heard of a situation where it has.

Redcare GSM.

Redcare GSM was the next generation of signalling product and  was developed in order to give police a confirmed alarm in order to comply with DD243 that came into effect earlier this decade. It allowed the secondary path to still tell the central station exactly what was happening even if the line was cut. This mean that you could have a com fail followed by a code 3 burglary signal and you could be certain a break in was occurring. The Police of course were very pleased with this solution and again we do not know of any circumstance where it has been defeated.

Competition.

In recent years Redcare has finally come under pressure from other products. It has enjoyed many years where it dominated the intruder alarm signalling market place but broadband has started to change all this. Being a BT product it has always needed a BT line to allow it to work but now Broadband means that some sites don’t even have a BT line on site.

Solution.

Redcare Secure is the latest product that BT have launched and this is aimed at sites that have installed broadband and are considering competitor products such as Emizon (integrated into the Castle Caretec Euro 1 as standard), DualCOM or Chiron. It is cheaper than previous Redcare products and promises to help Redcare recapture some ground lost over the last two or three years.

Conclusion.

Despite claims to the contrary Redcare is very much still a favorite of the Intruder alarm industry and the major insurance companies still make reference to Redcare being the primary product that should be installed in order to meet their requirements. Redcare have a major conference in Birmingham during IFSEC week to show off new products. It will be interesting though to see who comes out on top under the new challenging conditions created by the changes within the communication market place.


VCL Dome servicing.

VCL Dome camera.  Buy spares

VCL in their time produced and sold one of the most successful dome cameras in both the UK and Europe. During the early part of this decade the VCL dome camera was renowned for its picture quality and ease of programming. Many  companies across the UK had the dome installed and there are still many thousands of them out there, many are still working perfectly well.

VCL dome repair.

Time however is moving on. A dome of course has moving parts, the most vulnerable of these to wear being the slip rings and both the pan and tilt motors. The VCL dome cameras can of course still be repaired and there are still companies that will do this. However these repairs are rarely cheap and as to how long they will last , who knows . Add to this the expense in certain cases of hiring a cherry picker to both remove and then re-install the camera and you start to look at thousands rather than hundreds of pounds.

VCL dome fix.

A solution is available though. Integrated CCTV have sourced a fix whereby the housing can be re-used and only the inner is replaced. This inner is produced by a renowned dome manufacturer and a lot of research has gone into manufacturing the bayonet to integrate seamlessly into many models of the old VCL dome housing. This fix is almost always a cheaper option than actually carrying out a full repair on the old inner. What is more the new camera comes with a full year guarantee therefore giving the end user confidence that he will not be re-hiring access equipment just a few weeks or months down the line to once again repair an ageing camera.

So if you have grown frustrated with constantly being let down by a repair that never seems to last contact us and we will happily point you in the right direction.

Samsung v Videosphere-Wide dynamic v Megapixel

Posted on by

Case study.

Integrated CCTV were recently asked to carry out a very interesting camera comparison in order to establish prior to an installation the effectiveness of  two different types of cameras and how they performed when used for two different applications.

Solutions must be found.

The customers main issue was that he needed to identify if stock became damaged on his premises while being loaded or unloaded onto his vehicles. The problems he had encountered in the past was that while looking out from his warehouse into the rear of the lorries the sunlight adversely affected the camera picture and his ability to view the stock inside the trailer. In addition, when replaying any events, when he zoomed in to get more detail, the picture became pixelated and unusable. Also cameras inside his warehouse viewing staff, never gave him the detail required for the wide angle view he wanted and so incidents frequently were either missed or when replayed, offered no real information that he could use.

Wide dynamic or Megapixel IP camera.

With this in mind, we chose to trial two cameras, the SCC-b2335p Samsung wide dynamic static camera and the Videoshpere 1080p Megapixel IP camera from March Networks.

Camera lenses.

To get the best comparison we used very similar lenses, the 2.8 – 8mm on the wide Samsung camera and the 2.2-6mm on the 1080p Megapixel IP camera. We set both cameras up on a tripod and powered the 1080p with POE as designed. The Samsung camera was converted to IP using the March Networks encoder so we were able to bring both cameras back into the Videosphere VMS CCTV software for recording purposes and then after the trial, demonstration of our results to the customer.

The test.

Firstly we positioned our vehicle in the loading bay and pointed both cameras out through the warehouse door. The boot of the vehicle was left open so all the goods inside could be seen. Or at least we hoped they could be seen but on initial power up, both pictures proved to be very disappointing. It was a very bright day and the warehouse had limited natural lighting and no artificial light at all . As a result, we could see little or nothing of the contents within the car, the reason of course was the huge difference in light levels between inside and out. We then turned on the back-light compensation feature within the Samsung wide dynamic camera. This made a huge difference. The Samsung camera then gave us a clear, crisp image of the boot contents and we were considerably impressed. We looked for a similar feature within the Videosphere 1080p but there seemed no adjustment we could find that would improve the picture and despite the progressive scan that we had hoped would help, the images had  to be classed as un-useable.

Playback.

We then played the Samsung images back on the VMS CCTV software we found we could zoom in to the boot contents up to 2x before any pixelation occurred and we deemed that with the camera position we could attain using brackets hanging from the warehouse roof ,we would be able to deploy the Samsung camera successfully.

Looking at movement inside the warehouse.

Onto our next issue, this was getting detail from a wide angle view of staff movements inside the warehouse. The areas that needed to be covered by each individual camera were approx 25m by 50 meters and the number of cameras had to be kept within reason to keep costs within budget.

Looking into the dimness!

Both cameras were turned round to take in the view described above. We identified a few distinctive objects at certain distances to help us compare the pictures. Both cameras offered up good pictures but the image quality from the Videosphere Megapixel IP camera could only be described as stunning. The clarity was incredible considering how low the light level and the distance we were asking it to look. However we were to be even more impressed when we looked at the playback . Even when zooming right to the back of the warehouse the pictures were of superb quality.

Image storage issues.

We must not however forget that with this quality comes certain issues. Data storage when using IP Megapixel cameras runs in several terabytes and this pushes up the cost.

Customers opinion.

We then took the opportunity to show the customer the results of the trial he was very impressed with the results of the Samsung B2335P. For a long time he has been looking for a camera that can cope with extreme lighting issues and he now finally has a solution. With regard to the Videosphere Megapixel IP camera the pictures quite simply sold themselves as he said “it’s a no brainer I have got to have these in my warehouse”. Of course there are price issues, this sort of quality cannot come without cost implications.

Conclusion.

In conclusion the review and testing highlighted the fact that there has never been a clearer example of the fact that there is always the need for the right camera for the right job. Careful testing and specifying will ensure we get a happy customer at the end of the day. The Samsung wide dynamic camera definitely performed as designed and as for Megapixel Ip camera technology the picture quality was fantastic . This can only help to make these cameras a very popular choice with  forward thinking customers.

Why appoint a CCTV regulator?

Posted on by

New IP solutions encourages new appointment.

Why has the UK government decided to appoint an interim CCTV regulator? Well Andy Rennison certainly has a big task ahead of him. To be fair it seems on the surface just another public servant being appointed just for the sake of it. We already have regulation within the industry in the form of the NSI and this is effectively controlled by the government already through the implementation of European standards for intruder alarms, access control and CCTV.

The challenges ahead.

There are however some challenges ahead within our industry that to the credit of government officials have actually been foreseen at a relatively early stage. Integration between CCTV, access control and intruder alarms mean that the boundaries are becoming blurred between the security technologies . Of even more relevance is that CCTV evidence produced by camera systems has always been contentious but now with the advent of IP CCTV and integrated CCTV systems mean that the police and the courts are desperately seeking guidelines and regulation to ensure that evidence that is forth coming from the new IP surveillance systems can be used in the courts  and this is very much in the public interest.

Government interference?

Government intervention can only be justified if it is profoundly in the public interest and with CCTV software being used more and more, guidelines are are must to ensure forensic integrity is maintained and all evidence is 100% acceptable however it may need to be used.

Complaints procedure for CCTV systems defined by the CCTV regulator.

The right for the public to be able to complain is only a step forward if there is a real understanding in the public domain as to how IP CCTV works . So if education is part of Andy Rennison’s  remit then this cannot be viewed as bad thing.

Conclusion.

Within the industry we have to look at this in a positive way. No publicity is bad publicity and if it means that high standards are enforced then only the most professional companies will be able to take on the new challenges set out by the new CCTV regulator. We look forward to the way this develops with interest . Your thoughts are welcomed. Do we need this kind of regulation or can the industry be relied upon to govern itself ?
