Ubiquiti USL-Entry, UniFi Protect Entry Sensor, 3 pack

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 instantly sends notifications to the UniFi Protect system. The 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 buildings — from households to commercial spaces.

High longevity and durability for long-term operation

Thanks to its 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. Certifications of FCC, IC, CE, and NDAA Compliant enable deployment even in professional security systems.

Easy installation and full integration with UniFi Protect

Installing the sensor is exceptionally easy – it attaches using double-sided tape or screws, and the magnet is placed on the movable part of the door or window. Once connected to the UniFi Protect system, remote monitoring can be performed through both the web and mobile application (iOS/Android). With a functional button, factory reset option, and detailed diagnostic features, the device is ready for immediate deployment without complex configuration.
