Protech SDI77XL2D Dual Technology Intrusion Sensor, Vertical Barrier, Lens D, 100' 10'

Protect your perimeter with precise, low-false-alarm detection. The Protech SDI77XL2D Dual Technology Intrusion Sensor is engineered for vertical barrier applications, delivering reliable monitoring across a 100' x 10' detection zone. Combining stereo Doppler microwave sensing with dual-element infrared (PIR), this outdoor motion sensor minimizes nuisance triggers while maintaining consistent performance thanks to balanced temperature compensation.

Designed for professional security and surveillance deployments, the SDI77XL2D mounts to poles for clear line-of-sight coverage and uses wired DC power for dependable uptime. Its dual-tech approach enhances intrusion detection for fences, gates, and building approaches, making it ideal for perimeter security, critical infrastructure, and commercial sites that require continuous monitoring. The sensor’s compatibility with standard alarm systems simplifies integration into existing access control and monitoring platforms.
