<p>The invention relates to surveillance apparatus for use in a closed circuit television (CCTV) security system, comprising a self-contained surveillance unit (2) which is provided with means, such as a mounting tube (10), for fitting the unit (2) to the top of a conventional lamp post (1) or the like in place of the normal lamp unit. The surveillance unit incorporates a plurality of CCTV cameras (13) individually adjusted and fixed to survey the required areas of a site. Each camera (13) is associated with a radio transmitter for transmitting video data to a remote central point or control station. The surveillance unit (2) also incorporates its own power supply comprising batteries and a solar panel (5). The combined lamp post-mounted surveillance unit is therefore self-contained and free-standing.</p> |
