Protech SDI-76MW Indoor Microwave Intrusion Sensor, 50 x 50' (15 x 15m)

Protect critical indoor spaces with the Protech SDI-76MW Indoor Microwave Intrusion Sensor — a high-accuracy PIR motion sensor engineered for professional security and surveillance applications. By combining PROTECH’s stereo Doppler microwave technology with passive infrared sensing, the SDI-76MW delivers dependable 50 x 50' (15 x 15 m) coverage and significantly fewer false alarms compared with single-technology detectors. That means more actionable alerts and less wasted response time for security teams.

Built for professional monitoring and integration, the SDI-76MW accepts 8.5–20 VDC power and can operate on battery power for redundancy, while its compact 3.3" height and 6.5" length allow unobtrusive installation. The sensor’s wide operating temperature range (-4 to 155°F) ensures consistent performance in a variety of indoor environments. Ideal for server rooms, storage areas, retail backrooms and high-security offices, this Protech intrusion sensor is optimized to fit into existing alarm and access-control systems, improving overall site surveillance and operational reliability.
