Ubiquiti UniFi Entry Sensor - USL-Entry

At a glance:

• SuperLink sensor with up to 6-year battery life for monitoring door and window open/closed status.
• Long-distance and low-power connection
• Adhesive and screw mount

The USL-Entry sensor is a sleek, battery-powered wireless contact sensor designed to bring dependable open/close monitoring to your UniFi Protect security setup. Utilising Ubiquiti’s proprietary SuperLink technology, this device offers extended wireless range—up to 2 km line-of-sight in ideal conditions—making it suitable for larger homes, outbuildings, warehouses or any environment where traditional short-range contact sensors may struggle to maintain a connection.

Unlike basic sensors that rely on Bluetooth or Wi-Fi, the USL-Entry pairs with a SuperLink gateway to transmit status changes of doors and windows directly to your UniFi Protect interface in real time. Placed discreetly on frames with the included adhesive or screws, the compact reed-switch design instantly detects when an access point is opened or closed, feeding that information back into your centralised monitoring system without the need for complex wiring.

Powering the sensor is a long-lasting CR123A lithium battery that can deliver up to six years of service under typical use, dramatically reducing maintenance visits and ensuring continuous performance. The robust wireless link, combined with low-power operation, allows this sensor to stay connected and responsive even when paired with multiple devices across a larger property.

Installation is straightforward: once mounted and adopted via UniFi Protect, the sensor begins reporting immediately, making it easy to configure alerts, automation events or logging through the UniFi Protect mobile and web apps. With its durable polycarbonate build and simple integration into your broader security ecosystem, the USL-Entry adds a vital layer of access awareness that helps improve situational insight and reinforces your overall safety strategy.
