Finally, a plan called an ultrasonic occupant sensor uses a system that sends out ultrasonic waves, which then select up on how often these waves are reflected. Operating considerable like naval sonar devices, these sensors detect motion through a change in the frequency of the waves that are reflected. These devices are among the most sensitive sensors when it comes to detecting movement.
RAB is one of the leading manufacturers of motion sensors and provide a variety of sensors, each configured for specific purposes. One of the most accepted models is the Stealth 110. This unit provides 110-degree coverage, which translates to 50' out and 70' wide. Generally obsolete in commercial or industrial settings, the Stealth 15LV is primarily worn as a motion detector in corridors. This unit has a 15-degree coverage and can detect motion as far away as 75' using a 12' scan. The Stealth 200 provides 200 degrees of coverage or 30' out and 100' wide.
