Protech SDI-77XL2 Dual Technology Intrusion Sensor, Wide Angle, Lens A, 90' 50'

Designed for dependable perimeter protection, the Protech SDI-77XL2 Dual Technology intrusion sensor combines passive infrared and microwave detection to deliver accurate outdoor monitoring with fewer false alarms. As a high-performance PIR motion sensor, the SDI-77XL2 uses a Wide Angle Lens A to cover up to 90' x 50' (maximum sensing range to 125') so integrators can secure large entryways, loading docks, and open grounds with a minimal device footprint. The dual-tech logic requires both technologies to trigger before an alarm, giving security teams greater confidence and reducing nuisance responses.

Built for professional security and surveillance systems, this outdoor, wired sensor accepts 20V DC input and mounts easily to walls for reliable, hardwired connectivity to control panels. The tamper-resistant enclosure and rugged US-made construction provide long-term durability for commercial installations. Ideal for intrusion detection, perimeter monitoring, and critical infrastructure protection, the SDI-77XL2 streamlines installation and improves overall system integrity. Add the Protech SDI-77XL2 to your next perimeter security design or contact sales to specify it for commercial surveillance deployments.
