Video sphere VMS software

Why VMS ?

There are many benefits being touted about Video sphere VMS software.The main one we can see is the ability to support so many applications and be so flexible when trying to design a hybrid CCTV system.

The framework to have a scalable IP CCTV solution.

Video sphere can support small, medium and large applications that need IP CCTV solutions but need to consider legacy analogue devices . By using codecs all analogue camera equipment can be converted to IP CCTV cameras and integrated into the VMS framework. Video streaming of high frame rates up to 256 IP or converted analogue cameras per server. Ultimately by correctly configuring the network servers VMS can support thousands of cameras across a company group.

MPEG4 and H.264.

Both the above video compression formats are supported by VMS as is multiple PTZ IP cameras and video sphere HD IP solutions. As we mentioned before codecs in the form of Edge encoders are used to introduce analogue cameras in to the overall solution and this then enables existing equipment to run analytics that make these cameras intelligent this has to be considered a valuable upgrade benefit.

Alarm switching.

An important part of all IP solutions is the ability to support alarm switching to follow analytic generated alarms. VMS does this and can also be integrated to data sources such as ATM and POS transactions.

Conclusion.

VMS is a powerful piece of software , designed to be future proofed and has many features and benefits that will suit designers of IP camera solutions and integrated CCTV. It does need a robust server to work in unison with it that can back up recorded images effectively and this does add to the cost. However VMS does offer the maximum flexibility and has many benefits over black box solutions that ultimately will become a thing of the past over time.


Monitored CCTV

What is monitored CCTV.

Monitored CCTV first started to come into its own in the late 90’s .This coincided with the advent of the ISDN telephone network that BT developed in order to transfer large amounts of data mainly for large corporate customers. The first ISDN lines were made up of two legs of 64k each giving a total of 128k. This was sufficient to allow CCTV images of reasonable quality to be compressed and transmitted using an ISDN modem.

CCTV monitoring station.

The early monitoring stations tended to use two formats for monitoring these pictures. As a rule they used either the Adpro or the DVST transceivers. It was a bit like the VHS/Beta Max battle when the VCR was first developed and the market for monitoring at that time was only ever going to be able to support one monitoring platform in the early days and as a consequence  the DVST solution lost and died a slow and expensive death.

What did the operator see?

It was quite simplistic really. The Adpro was able to transmit three separate snap shots each taken approximately one second apart. This was presented to the operator in the form of a quad image, the three snap shots and in the bottom right hand corner was the live streamed image. It had to be remembered that this was early days and the images were of questionable quality . Great skill was required on behalf of the operator to distinguish whether there was actually a break in occurring . Of course when the central station only had a few connections this was not a problem the operator had plenty of time to spend on each alarm ,but, this was soon to change.

The boom years.

The popularity of monitored systems took off as we entered the 21st century. Connections increased massively and central stations were only too keen to take these on. It did however mean that as these connections increased, the service to the end user started to decline ….dramatically.

False alarms.

False alarms were a considerable drawback to the industry, in the absence of regulation any CCTV installer could make a connection. Design of the systems seemed to take second place to the number of connections that could be made and as a result break ins were missed and litigation followed.

Re-think.

This made the central stations re-think their position and actually forced them to decline applications from installers who had a poor record of false alarms. Some sites were disconnected in an attempt to get false alarms and response times under control. It took a long time but with some heavy handed tactics from the central stations,  including isolating cameras that caused more than just a few activations in a 24hour period. Everyone started to appreciate the need to reduce dramatically the number of false alarms being signalled through.

IP solutions.

Of course as technology improved, Adpro was being challenged by some new players in the market place. Slowly but surely with the advent of IP monitoring it started to lose its grip as the main player. Broadband means better pictures and faster connections and also the ability for central stations to view pre- alarm events giving them far more information. There is still a school of thought however that IP monitoring is not always as secure as we would like to think. We have down time  at ISPs and certainly there is a percentage of information that is lost in the Internet cloud.

So where does CCTV monitoring go from here?

We need think hard about this one. IP camera systems mean that monitoring needs are changing and fast. Large organisations are beginning to realise that monitoring there own sites is a possibility and and that cost savings are possible. Hybrid CCTV systems will become the norm and it will only be a matter of time before ISDN is phased out completely so all the old legacy transmitting equipment will have to be upgraded. A great opportunity for installers and manufacturers alike. As for the monitoring stations they need to keep a very close eye on the market place .They must implement front end software that can integrate to as many legacy and new transmission products  as possible into its central station. Ineveitably they will have to reduce the cost of monitoring solutions in order to both maintain existing customers and generate new business


Car dealer is spending 70K on security guards

Cost savings. Are they realistic?

We have talked about integrating various systems together without actually giving any real examples so below is one that integrated CCTV came across late last year and the solutions we provided.

The scenario

A large car dealer is currently spending nearly £70k per annum on a manned security guard to look after their site 365 days a year. Although the guarding company is doing a fairly good job, a risk assessment has proved that in the case of a break- in the chance of him being in the right place at the right time is slim. Therefore the company in question has concluded that it needs to source a far more cost effective method to secure the site.

Where can the cables go?

The site is 30,000 square meters and has no real secure fencing, anyone can enter the site at will and they have millions of pounds worth of stock on show. Due to the lack of fencing there are no real cable routes and also no fixing points for sensors on the perimeter and the whole site is block paved and this leaves no opportunity to trench or put up many poles.

The solution… Integrated security!

We concluded that a radical solution was required. One that used cutting edge technology together with an effective visual and audible deterrent, We also need to effect a manned response to a genuine alarm situation but not scare off any genuine customers viewing cars up to a certain time in the evening.

To add to our problems as mentioned before there was very limited scope to fix poles and run cables so sensors and fixed beams had to be ruled out. There was only one realistic answer left and this was to use analytics to generate alarms.

Light levels

The light levels were good and we decided to recommend a mixture of IP, wireless and traditional analogue cameras together with analytics to get the ultimate system and bring it in within budget.

The cameras on the building are wired in a traditional way, coax back to a standard codec to produce the analytics, then onto a hybrid DVR that was connected via broadband to a remote monitoring station. The IP cameras on the perimeter are to be  fixed  onto just two poles and linked via a wireless IP transmitter back to the hybrid dvr.

Controlling alarms

Sitting in between this was a control panel used to process alarms, generate on site verbal deterrent and sounders designed to remove unauthorised intruders. If this failed then the system was designed to call out the manned response but only as a final measure again helping to keep on going costs to a minimum.

Analytics

The use of analytics to generate the alarms however was the key to this working. Only in very recent times have we been able to use them effectively outside and in limited lighting conditions. This type of alarm generation will soon supersede traditional sensor technology and can only get better and better as large cooperation’s begin to invest heavily in analytics.

Conclusion

In conclusion the recommendations mean the car dealer now has the opportunity to lower security costs and will start to see savings filter through after 18 months or so. He has a system that is future proofed for at least the next 5 years and beyond. He has eyes all over the site 24/7/365 and as well as better security he has also got a sales tool and a health and safety watchdog as well as a deterrent system. Quite a few benefits for a great deal less money.

Things to look out for in the coming weeks on this site

Saving money on security guards

We look at a case study for a site that was spending over 70 thousand pounds a year on security guards. We discuss how this can be cut to a fraction of that cost by using  Analytics.

FLIR thermal imaging cameras.

We look into the new thermal imaging camera released by FLIR that is light and very cost efficeint  something we all thought would be impossible for a thermal imaging camera.

ANPR cameras. 

 How they work? and where they are being used today.We highlight some good and some bad points about them.

Biometrics.

We ask whether this technology is ever going to become as big within the security market place as it promised to be when it was first launched.

Adpro and IP.

Can Adpro ever get back to where they were in the CCTV transmission market place. It was not so long ago they were the only choice when transmitting CCTV images.

CCTV distributors.

We discuss whether CCTV distributors need to look at a different route to market now that IP cameras are so popular.

Emizon IP.

We talk about Emizon and what it means for IP intruder alarm monitoring.

Raytec.

This revolutionary new lighting technology has turned a few heads but will it replace all the old halogen lighting systems out there?

NSI.

Does the security industry need this regulator and how will IP camera systems impact  on this inspectorate?

Insurance claim against security providers. Should you pay up?

Posted on by

You provide the security, there has been a loss . Who is to blame?

So the scenario is as follows. You are a CCTV installer and you provide images and alarms to a central station. The security system and CCTV camera have worked very well as part of an integrated system over the last few years but then there is a massive loss on site and all of a sudden the customer is screaming at you and wanting you, the CCTV supplier to pay up for his losses. A situation that could cause a lot of friction and bad feeling, but worse of all, the loss of a major contract and a very important customer.

A familiar story

It happens frequently and the blame more than often lies somewhere in the middle between the suppliers of the CCTV monitoring, the customer and the installer.

As installers the main protection when we have integrated systems against the accusations thrown at us are; the specification, the evidence held at the monitoring station and the CCTV camera footage.

Was the CCTV system set?

This may sound obvious but it is always the first question that must be asked. So many times during a post robbery investigation it turns out that the system is left unset, if this is established then the security providers need worry no further.

Was the coverage compromised by the customer?

This may again sound obvious but so often the customer may block coverage of the sensors  or CCTV cameras and so the system cannot possibly work properly. Generally reviewing the CCTV camera footage on the DVR will soon clear the installer if the customer is at fault.

Third party issues

What happens then if everything is on site but the receiving centre has not got the pictures?. Well is it the remote connection I.E telephone or broadband that has let the system down? The logs in the DVR should be able to prove if this is the case and will tell the installer again if any blame can be placed on him.

The central station

Finally of course we have central station operator error, This to needs to be eliminated because generally remote monitoring is sub-contracted to the central station by the installers. Ultimately the installer is still responsible for the central station’s actions. Once again proof will come from the recorded images held by the Central station, any voice recording they may keep and the central station log that will record all activity received.

Insurance

But really the whole thing is an insurance issue. CCTV companies cannot possibly factor in losses to the price they are able to charge for an installation. Surely this is why insurance companies are in business. Of course if the CCTV company is proven to have been negligent then this is something for the insurance companies to sort out through the loss adjusters at a later date.

In summary

So for customers and installers alike hopefully this bit of advice will raise enough questions at the point of sale and through out the company /customer relationship to realize that all parties have a part to play in ensuring that a CCTV system works effectively, every time.
