The Watchman system provides a fully portable area security system where there is no pre-defined perimeter. Each Watchman pack comprises of six independent ground based sensor units with a detection radius of 6 m covering between them a total of 100 square metres. If a human being enters the monitored area, the sensor detecting the intruder emits a signal to the central unit, which displays a warning light in conjunction with an acoustic alarm. The light identifies which sensor has been activated and thereby the position of the intruder. Signals between the remote units and the central control are transmitted wirelessly up to a distance of 2000 metres.
Positioning and activation of the units is extremely straight-forward; each Watchman is self testing, and confirms its operational functionality to the central control which displays a green light accordingly. The units are powered by NiCd batteries which are recharged from the central console every 8-14 hours. Operating temperature range extends from -40°C to +80°C.
