Roboguard is a stand alone, wireless automatic outdoor security system using passive infra red sensor beams that detect movement up to 20m away in a 110 degree arc. Each guard has two sensors, one on top and one below emitting 11 beams each. Both beams must be broken within half a second to trigger an alert.
