Prestigious larndmark benefits from integrated IP CCTV that improves flexibility and reduces costs
The £800m refurbishment and extension of St Pancras International is part of HS1, Britain’s first major rail project for over a century and the UK’s biggest ever construction project. Opened by the Queen in 2007 this prestigious landmark required an advanced CCTV solution to help protect staff, customers, and visitors to the station. Controlware won the contract on the basis of the advanced technical solution, integration expertise, and the proven ability to deliver large projects successfully.

Security both inside and outside of the location is a key factor in developing a safe environment. It is essential that the CCTV surveillance cover more than just site boundaries but ensure staff and public safety as a whole.
The application of new and future technology into an integrated solution can effectively assist in both crime prevention and management of incidents as they occur. The key components of a security solution typically comprise of video surveillance, video recording, communication and alarm detection. If each of these systems is implemented separately and independently, management, efficiency and usability will inevitably suffer as a result. Alarms occur on one system, access control is managed on another system, recording and viewing by another and so on. This means that operational usability becomes difficult, training needs more comprehensive, and maintenance more complex.
An effective security system needs all of these components working together in harmony to create a seamless unified solution. When utilising multiple separate companies to provide these systems problems usually arise as there is no one company who is responsible for ensuring the collective parts all work together. In addition, many systems are using proprietary technology that does not lend itself well to integration, often made worse when the manufacturers are unwilling to share necessary information about their systems.
By utilising a single organisation who can integrate these separate security components and technologies under a flexible CCTV and security management system, you benefit from a considerably more powerful and effective security solution with a lower total cost of ownership.
Like many sectors of the security industry, the devil is in the detail and system integrators and end-users who wish to see the benefits of an IP-based solution should look to someone who really knows the technology and can give an impartial view. It is common sense that manufacturers will only support their own hardware and will promise the earth for it, whereas a distributor will have evaluated a number of solutions from different vendors and be able to say that product A is the best for solution B because of XYZ whereas product Y is the best for solution C because of etc etc.

The final part of the case for H.264 by Mark Harraway, UK Country Manager
Q. H.264 may prove unsatisfactory in situations where low latency is important. Is there any truth in this?
Again, I would have to say it depends on which manufacturer you are using. Latency is a function of the network – available bandwidth vs amount of traffic generated. As we have already said, using H.264 should improve network latency as you are reducing the bandwidth on the network by pushing the work to the edge device. If the concern is image delay (perhaps moving one’s hand in front of a camera and then seeing this on the screen), the issue comes down again to the truism that you get what you pay for. Higher build standard encoders or cameras will give quicker response times as they have faster processors and the manufacturers are likely to have implemented the profile better. Again this can all be adjusted in the individual codec settings.

The eighth part of the case for H.264 by Mark Harraway, UK Country Manager
Q. What is more important for end-users, reductions in RAID demands or usable images with reduced bandwidth? How does H.264 fare on both, and are there variations within industry sectors?
Only an end-user can answer this since factors include a mix of budget, space, and quality but it is important to note that H.264 and IP give you the flexibility to tailor the system to meet on-the-ground needs. By contrast, in an analogue or DVR-based system, it is the hardware that dictates matters through supported frame rates or recording space in the box. The beauty of an IP / H.264 system is that you can be dynamic in the offering. After all, why record at a high frame rate or resolution when nothing is happening? The way forward must be to move to event or alarm-driven recording. And if you really do need 24/7 recording then use the power of H.264 to reduce your bandwidth and thus your storage requirements.

The seventh part of the case for H.264 by Mark Harraway, UK Country Manager
Q. H.264 has been described very patronisingly as ‘promising’, presumably by those in the analogue camp or supporters of other standards who don’t want this new offering to prosper. Are there parties in the industry who want to impede the progress of H.264 by ‘damning it with faint praise’?
Again, this is the “We can’t offer or work with it so let’s rubbish it or at the very least pour cold water over it” tactic. IP and H.264 are the future of CCTV and just as magazines are no longer produced with typewriters and the old ‘hot metal’ printing technology, end-users shouldn’t listen to entrenched analogue adherents when making decisions on the future of their systems. I would be more than willing to place an H.264 offering up against a like-for-like analogue system in an independent test to prove its worth.
