Ubiquiti USL-MOTION SuperLink Motion Sensor

The Ubiquiti USL-MOTION is a compact wireless motion sensor built to integrate into UniFi Protect surveillance and access control systems. This device operates as a trigger point for event-driven recording and automation across distributed physical security deployments, solving the problem of monitoring low-traffic areas without continuous recording overhead.

Overview

The USL-MOTION (MPN: USL-MOTION) pairs with UniFi Protect controllers and cameras to provide motion-activated events that drive recording profiles, alerts, and access control workflows. It draws only 22.6mW via a CR123A lithium battery rated for up to 6 years of operation — meaningful for locations where hardwired power is impractical or deployment is temporary. The polycarbonate and HDPE enclosure tolerates 0–40°C ambient conditions and operates across 10–90% noncondensing humidity. Two separate PIR sensors deliver 1.5m horizontal detection and 6m vertical detection with built-in pet immunity, reducing false triggers in mixed-use spaces. The device communicates via SuperLink proprietary wireless on 915.6–927.6 MHz (US) or 865.1–869.5 MHz (EU) with 14 dBm max transmit power and 2 km maximum range. Wall or corner mounting accommodates flexible placement in corridors, entryways, stairwells, and blind spots between fixed cameras. Factory reset and function buttons enable field reconfiguration without specialized tools. Status and signal LEDs (R/B/W indicators) provide instant visual feedback during setup and operation. NDAA-compliant and FCC/IC/CE certified.

Compatibility

The USL-MOTION integrates natively with UniFi Protect (web application, iOS, and Android mobile apps) as a managed sensor within distributed deployments. It operates within UniFi ecosystems running Protect controllers — no third-party bridge devices, middleware, or custom integration required. Motion events propagate directly to the Protect controller for rule-based automation. Not compatible with non-UniFi systems or legacy surveillance platforms.

Installation Notes

Mount using the included polycarbonate wall bracket with adhesive or screw fasteners. Device dimensions with wall mount are 93.5 x 22.5 x 24.7 mm (3.7 x 0.89 x 0.97"). Corner mount variant is 93.5 x 22.5 x 27.9 mm (3.7 x 0.89 x 1.1"). Install the CR123A battery (included in deployment) and commission through the UniFi Protect mobile or web interface. Orientation of the vertical PIR sensor determines detection range — mount with the sensor facing the monitored area for optimal 6m vertical coverage. Horizontal PIR provides 1.5m range perpendicular to wall surfaces. Keep away from direct heating vents, air conditioning outlets, and strong infrared sources to minimize false motion events.
