Wireless site security

摘要

Clarke Construction Security Ltd (CCSec) has launched a new wireless site security system. The new wireless, dual-beam, high power, radio-linked detector is battery-powered and movable. The rugged, low-maintenance radio transmitters communicate with a base station day and night, while the DUAL beam passive infrared sensor (PIR) technology eliminates the risk of false alarms and has a 40 metre detection range.
