Ubiquiti UniFi Protect Entry Sensor - Reliable Door and Window Monitoring
The Ubiquiti UniFi Protect Entry Sensor (USL-ENTRY) is designed to provide seamless monitoring for doors and windows, helping you enhance security and gain real-time alerts when access points are opened or closed. With long-lasting battery performance and robust SuperLink connectivity, this entry sensor offers a dependable solution for residential and commercial environments. Its compact design allows for easy installation using adhesive or screws, while integration with the UniFi Protect application ensures simple management and monitoring from your mobile device or web interface.
This entry sensor is equipped with a reed switch to detect open and closed states, paired with SuperLink proprietary connectivity for reliable communication up to 2 km. Its lithium CR123A battery provides up to six years of operation, reducing maintenance needs. The device is crafted from durable polycarbonate, includes a tamper switch, and has clear LED indicators for status and signal. Installation is flexible with adhesive or screw mounts, and it seamlessly connects to the UniFi Protect ecosystem for centralized management.
Compact Design and Easy Installation
The entry sensor comes with a main device measuring 75.5 x 23.5 x 22.5 mm and a magnet at 39 x 15.1 x 12.9 mm. Lightweight yet sturdy, the device weighs just 41 g and the magnet 22 g. Both components are constructed from polycarbonate, ensuring durability without bulk. Mounting options include adhesive for a quick setup or screws for a more permanent solution.
Reliable Connectivity and Performance
This sensor operates with SuperLink proprietary connectivity, providing a maximum range of 2 km in open environments. Transmission power reaches up to 14 dBm, and the antenna gain is 0 dBi. Operating frequencies vary by region, including 915.6-927.6 MHz for the US and 865.1-869.5 MHz for the EU.
Battery Life and Power Efficiency
Powered by a single 3V CR123A lithium battery, the sensor consumes a maximum of 27.7 mW, delivering up to six years of operation under normal conditions. This minimizes maintenance while ensuring reliable monitoring over extended periods.
Smart Sensor Capabilities
The sensor features a reed switch for detecting open and closed positions, a tamper switch for added security, and one function button for easy operation. Two LED indicators show status and signal strength, making troubleshooting and monitoring simple.
Environment and Compatibility
Designed for indoor use, the sensor operates in temperatures from 0 to 40degrees C and 10-90% non-condensing humidity. It is fully compatible with UniFi Protect mobile apps for iOS and Android as well as the web application, making remote monitoring straightforward. Certified to meet FCC, IC, and CE standards, it is also NDAA compliant for added assurance in regulated environments.
