# UniFi SuperLink Sensors Explained: Long-Range Wireless Security for Any Site

Published 08 Jun 2026 · Category: Knowledge · Web: https://level-floor.bnr.la/blog/unifi-superlink-sensors-explained/

*UniFi's SuperLink (USL) range adds long-range wireless door, motion, glass-break and environmental sensors to UniFi Protect — here's how the gateway and sensors work, and what to buy.*

Cameras tell you what happened; sensors tell you the moment it happens. Ubiquiti's SuperLink (USL) range brings long-range wireless sensors into UniFi Protect — doors, motion, glass-break and environmental — all managed alongside your cameras.


## How SuperLink works


A USL Gateway provides the long-range wireless link that the sensors talk to, then connects back to your UniFi system over PoE/USB-C. Because it's long-range, sensors can be placed across a whole house, warehouse or yard without per-room hubs.


## The sensor range


USL-ENTRY — door/window open-close detection
USL-MOTION — motion detection (also in 3-packs)
USL-GLASSBREAK — glass-break acoustic detection
USL-ENVIRONMENTAL — water leak, temperature, humidity, ambient light
USL-RELAY — I/O interface for integrating other systems
USL-FOB — remote control keyfob


## Home and SMB use cases


Home: door/window alerts, garage motion, a leak sensor under the hot-water system, a freeze warning in winter
SMB: after-hours intrusion (motion + glass-break), water-leak alerts in server rooms and stockrooms, temperature monitoring for cold storage

**Q: Do SuperLink sensors need their own app?**

A: No — they live in UniFi Protect alongside your cameras, so alerts, automations and history are all in one place.

**Q: How is SuperLink different from the UP smart sensors?**

A: SuperLink (USL) is the long-range wireless security range built around a gateway; the UP smart sensors are PoE/Protect environmental sensors. They complement each other — see our UP-Sense explainer.

**Q: What can trigger automations?**

A: Any sensor event — a door opening, motion, a leak — can drive automations like recording a camera, sounding a siren or sending a notification.
