This radar motion detector is a single-position microwave security sensor for perimeter and area protection, detecting human movement within a 2.5-metre-wide detection zone. Radar (microwave) detection has a decisive operational property: it senses motion by reflected radio signal rather than by sight, so it works identically in darkness, fog, rain, snow and dust — conditions that defeat optical sensors and degrade cameras.
Single-position architecture means the unit transmits and receives from one housing, simplifying installation compared with two-post barrier systems: mount the sensor, orient the zone, connect to the alarm panel. The defined 2.5 m zone width allows precise corridor-style coverage along fences, walls, rooftops and approaches without spilling detection into neighbouring areas where false alarms originate.
At around $90 with a minimum order of 20 units, the detector addresses security integrators, perimeter-protection contractors and industrial facility operators. Microwave sensors of this class are the workhorses of site protection at energy, logistics and defence-adjacent facilities, where all-weather reliability — not camera analytics — remains the criterion that decides tenders.
