Ubiquiti USL-Entry, UniFi Protect Entry Sensor

The wireless entry sensor with SuperLink technology is designed for precise monitoring of door or window openings and closings. Thanks to the advanced reed switch, it provides accurate detection of changes in the magnetic field and immediately sends alerts to the UniFi Protect system. Wireless SuperLink technology with a range of up to 2 km ensures exceptionally stable data transmission even in challenging conditions. The sensor communicates on frequencies of 865.1–869.5 MHz, allowing its deployment in various types of facilities — from homes to commercial spaces.

High durability and resistance for long-term operation

Thanks to energy-efficient operation and a quality CR123A lithium battery, the sensor provides a lifespan of up to 6 years without the need for replacement. Its compact construction made of durable polycarbonate withstands temperatures from 0 to 40 °C and humidity up to 90%, ensuring reliable operation throughout the year. Integrated LED indicators inform about signal strength and device status, while the tamper switch detects attempts at manipulation. FCC, IC, CE, and NDAA Compliant certifications allow deployment even in professional security systems.

Easy installation and full integration with UniFi Protect

The installation of the sensor is exceptionally easy — it attaches using double-sided tape or screws, with the magnet placed on the movable part of the door or window. After connecting to the UniFi Protect system, remote monitoring can be performed via the web and mobile application (iOS/Android). With a functional button, factory reset option, and detailed diagnostic functions, the device is ready for immediate deployment without complicated configuration.
