A deployable intrusion system featuring an invisible electromagnetic detection
zone along a perimeter was on display at a recent trade show in Birmingham,
England. Manufactured by Senstar-Stellar Corp. of Carp, Ontario, Repels offers
a detection zone along the path of two parallel wires that are supported by
poles driven into the ground, said a company official. Unlike line-of-sight
sensors, this system can be rigged in any terrain, including hills and woods.
A single unit of Repels covers up to 385 feet. Multiple interconnecting units
can be employed. The detection field, which is impervious to radio frequency
interference, is about 6 and a half feet wide, and 6 and a half feet high.
