UniFi Protect Smart Sensor

The Ubiquiti UniFi Protect Sensor is a multipurpose security device designed for the UniFi Protect ecosystem. It provides environmental monitoring for homes and businesses that want integrated intrusion detection and status alerts within a single management platform.

Polycarbonate enclosure with LED status

The sensor fits into a UniFi Protect deployment alongside cameras and access control hardware, requiring a compatible UniFi console for configuration and recording. Its compact polycarbonate housing allows discreet placement on doors, windows or cabinets without occupying rack space or needing dedicated power wiring.

Battery-powered operation for sustained monitoring

Under continuous operation the unit runs on an internal battery, removing the need for mains power or PoE cabling during extended deployments. The multi-colour LED provides immediate visual confirmation of sensor state and network connectivity without relying on the console interface alone.
