The Ubiquiti Networks Entry Sensor (USL-ENTRY) is a SuperLink sensor that monitors whether doors and windows are open or closed, making it suitable for home or small-business users with a SuperLink Gateway who want entry-status monitoring.
Recommended For
- UniFi Protect users who want open/closed alerts for frequently used exterior doors or windows, with sensor events available in the Protect app and optionally linked to a camera.
- Homeowners or small-property operators who already have a SuperLink Gateway and want to monitor several doors or windows without routinely changing sensor batteries.
- People replacing a compatible existing alarm or smart-home contact sensor who want door and window status inside their UniFi Protect setup; one early owner reported quick notifications and straightforward adoption.
- UniFi users monitoring doors or windows in locations where pulling new sensor wiring is inconvenient, but where a SuperLink Gateway can communicate with the sensor.
