The motion detection alert system is a unique device developed by Cutting Edge Services to detect motion at your work place and deliver an audible warning or alert. The control unit can be programmed with a verbal message or sound effect (Subject to your requirements). The system contains infrared (PIR) sensors which detects moving heat created by a person walking within a maximum 12 metre range. A powerful speaker is supplied that sounds an alert when this motion is detected followed by a paused time-delay until activated again, also customisable per your requirements. The system is expandable for multiple PIR sensors and speakers, and comes with two as standard. All cable lengths from speakers and sensors are 3 metres as standard unless otherwise stated, system can be expanded to accommodate your layout requirements.
