A suitably specified and professionally installed surveillance system can be utilised in quite a number of applications, for example:

  • For pro-active monitoring and quick response in respect to human conduct:
    • In open public areas, retail outlet floor areas, at POS cashpoints
    • Within security or stock sensitive areas in an organisation, factory, or warehouse
    • To provide early-warning building perimeter intruder detection and detail
    • At security check-points, including the benefit of assisting in access control identification
  • To assist in investigations regarding improper conduct in respect of any of the above mentioned.
  • For pro-active monitoring and recording of industrial plant processes

The technology utilised in providing the above has improved dramatically since the advent of the first CCTV tube-cameras and video-machine-style recording systems.

Cameras now utilise CCD or CMOS technology and are either (as in the case of tube cameras) so-called analogue-signal type, or new generation IP-signal based (digitally-coded analogue-signal transmitted via LAN/WAN/Internet).

Surveillance cameras come in a variety of forms:

  • Traditional box cameras that allow custom lens fitment and usually require an external housing
  • Static (fixed) dome cameras (that usually look more aesthetic and are more discreet than box cameras)
  • Speed dome cameras that allow quick up/down and sideways rotation of the camera as well as powerful zoom in/out capability
  • Bullet cameras that often include night-vision infra-red LEDs
  • Thermal cameras that are an excellent means of long range night-time perimeter detection
  • Covert (small hidden) cameras
  • Vandal-proof cameras

The means of video signal transmission has also evolved from relatively short-range direct cable-to-recording device RG59 cable link, to long-range twisted-pair and fibre-optic transceiver transmission methods as well as wireless signal transmission. IP-based signal transmission plays a huge role here as well; as a result live video feed can be transmitted over far greater distances nowadays than previously.

Recording equipment usually incorporates either DVRs (digital video recorders) or NVRs (network video recorders), that allow multiple live display configurations and quick video search; sustained video-footage quality as well as multiple networking capabilities and support for alternate, mobile storage formats (such as USB memory stick).
