The benefits of digital CCTV

Tyco Traffic & Transportation offers a range of products and services for the transport sector

The digital age is encompassing all aspects of our lives, and the switch to digital format in the CCTV surveillance world is already well underway.

However, those who have a large legacy in analogue CCTV are left facing a huge expenditure to change their systems over to the latest digital platforms and are struggling to see how they can afford this quantum leap.

This problem is one that Tyco Traffic & Transportation has been keen to address and the company is now able to offer the seamless transition from analogue to new digital CCTV without the 'big bang' approach.

This allows the operators of current systems to implement the new technology while retaining and using within the same interface, the existing analogue components.

By using this gradual migration route, it allows the system to be renewed and updated without the need to find massive funding.
The digital CCTV system really starts to add value to the operation when more functionality is incorporated such as number plate reading, enforcement, incident detection, etc.

By integrating these applications into the central control system it becomes easier to manipulate the vast amounts of data and to quickly turn this data into usable information, even automating actions that need to be taken on a given scenario.

This frees the operator's time to concentrate on emergencies and other critical events. Also, with network video recording on the system, Mosaic, can provide quick and simple time/date based retrieval of evidence required, easily copied onto DVD for review at other locations.
Another key benefit comes when digital CCTV pictures are transmitted to operators on the move.

Tyco has developed a handheld mobile CCTV solution that delivers live video such as traffic flow or incident images direct to mobile users using a handheld PDA, notebook or desktop PC.

The system is ideal for personnel who need to access live video (including PTZ camera control) while on the move to provide a faster response to events or emergencies.

A major benefit is that the system uses existing GPRS or 3G mobile data networks which already have broad coverage so no expensive new infrastructure is required.

The system features an encoder capable of producing good quality video images over very low bandwidth data links- between 9.6 and 256kb/s. The quality of the images produced at 9.6kb/s allows monitoring of traffic flows while with faster 3G services and data rates to 70 kb/s. It also allows incident monitoring and management.

The low bandwidth keeps transmission costs acceptable and affordable for most situations. Video can be encoded from an existing CCTV system and transmitted to the remote devices, or it can be transmitted directly from remote cameras. It is ideal for rapid deployment of CCTV or for extending CCTV monitoring beyond the limit of existing infrastructures - enabling viewing of live video feeds directly from moving vehicles or vehicles parked at the scene of an incident. Tyco sees the system as being especially attractive for

traffic and incident management - but it can also be used to provide many other types of users with greater mobility while still being able to access live video images. As well as this mobile solution, wireless transmission is being increasingly used for static cameras and these vary from simple ADSL based systems, to the more sophisticated wireless mesh networks that can have diverse and self healing routing.

In the case of the latter, other data can also be combined with the system allowing UTMC functions and other traffic management signals to be carried. Not having to install expensive fibre networks (or hire bandwidth) and the subsequent disruption to city centre traffic is a clear benefit to the customer. These systems can also be more cost effective as installation times can be cut due to much lower requirements for street works.
