Digital CCTV features and benefits

Digital CCTV -vs- analogue
Digital CCTV is rapidly replacing the now defunct analogue systems. Many police forces have completed their upgrade from analogue to digital, and virtually all new installations will use digital technology. An analogy of the differences between digital and analogue would be Ipod -vs- cassette tapes.

Digital CCTV gives high quality images
Digital CCTV cameras convert the image into a stream of data that is transmitted to your server over standard network cabling. Because it is binary data, there is no loss of quality, no matter what the distance. The older analogue systems transmit signals over coaxial cable, and due to cable resistance, impedance, capacitance and external noise, the quality of the image when it reaches the controller is degraded.

Installation costs are low
Cameras can be connected to your existing network, which can significantly reduce the costs of installation. Cameras can even be powered over network cable, so cameras can be fitted in locations where there is no mains power nearly, again, reducing installation costs.

You can do everything from your desktop PC
Because the system uses standard network technology, you can view all cameras from standard PCs. You can control pan-tilt-zoom cameras using your mouse. You can review weeks of footage without having to leave your desk.

There are no video tapes to worry about
All images are recorded on a central server and retained for as long as you specify. There are no video tapes and no DVDs to worry about. All images from all cameras are constantly recorded, and the server has sufficient space to retain all footage for as long as you specify.

You can review recorded footage quickly
All footage is instantly accessible, so finding incidents is very easy. You can view all of the cameras' recordings simultaneously, so tracking the movements of a person through your building is very easy.

You can use SmartSearch to find motion within an image
The SmartSearch feature allows you to select part of a camera image using your mouse, and the system will search all recorded footage for motion in that area only. For example, in a busy corridor, you want to see who went into the cleaners' cupboard sometime over the past few days. By selecting just the top of the cleaners' cupboard door in the image, the search will stop only where the door has been opened.

You can copy footage to a DVD for evidence
CCTV evidence is easy to copy to DVD. The system comes complete with a suite of simple tools which enable you to make a stand-alone DVD containing player software and footage which the police can use as evidence. You might also choose to provide a DVD to a parent along with an invoice for repairs.

Your existing analogue cameras can be integrated into your digital system
Your investment in analogue cameras is protected because they can be connected to the digital CCTV system via a small 'black box' called a video server.
