CCTV

These systems can be as simplistic as one camera feeding into one monitor; equally the systems can be highly involved and complex. Applications of television can include process control, retail environments, crowd control, defence establishments and sports complexes.

Another application is in the monitoring of traffic flow; this can be motorways, railway stations and crossings, sea and airports.

Cameras can include facilities to pan, tilt and zoom into target objects. Operational capability can range from indoor high light situations to star light intensified units.

Where video recording is required, there are a number of options available which are as flexible as the camera systems themselves. This can be as basic as a single video recorder linked in line to the monitor viewing the system. It can be further extended to incorporate the video recorder working together with a conventional analogue multiplexer recording a number of pictures simultaneously. At the absolute extreme, the system can incorporate full digital recording where the images are stored on computer hard disks and where applicable, data support tapes to allow longer terms of times and recording. Systems such as the latter can be operated on a full network basis across the client's own network or alternatively, across the web using a web browser.
