Protech SDI-77XL-MW Piramid DIR Single Technology Stero Doppler Microwave Volumetric Sensor, H 60°, V 60°, 100x60' (30x18m)

Protect critical perimeters with dependable volumetric detection. The Protech SDI-77XL-MW stereo Doppler microwave volumetric motion sensor delivers precise motion detection for security and surveillance applications, reducing false alarms while maintaining high sensitivity to intruders. Listed under PIR Motion Sensors for category alignment, this single-technology microwave sensor provides a 60° horizontal and 60° vertical field of view and covers up to 100x60' (30x18 m), making it ideal for warehouses, loading docks, fence lines and site perimeters.

Built for installers and security managers, the SDI-77XL-MW offers straightforward mounting, flexible coverage shaping and compatibility with standard alarm control panels and monitoring systems. Its microwave-based detection maintains reliable operation in rain, fog, and low-light conditions where optical sensors struggle, delivering continuous monitoring and improved situational awareness. Low maintenance and scalable, this Protech volumetric sensor helps lower operational costs by minimizing nuisance trips and improving overall system effectiveness.
