Ubiquiti USL-MOTION SuperLink motion sensor

Ubiquiti USL-MOTION SuperLink Motion Sensor

Overview

The Ubiquiti USL-MOTION is a compact wireless motion sensor designed for integration into UniFi Protect surveillance and access control ecosystems. This device operates as a UniFi Sensor, enabling event-driven automation and monitoring across distributed physical security deployments. The USL-MOTION (MPN: USL-MOTION) delivers reliable motion detection in a polycarbonate enclosure rated for indoor and controlled outdoor environments, consuming minimal power through a standard CR123A lithium battery.

Key Features

The sensor operates across a voltage range of 3V and draws only 22.6mW during operation, extending battery life for infrequent monitoring applications. The polycarbonate housing with integrated high-density polyethylene (HDPE) mount material provides durability across the 0 to 40°C operating temperature range. Management occurs entirely through the UniFi Protect web application or native iOS and Android mobile apps, eliminating the need for proprietary management infrastructure. A factory reset button allows field reconfiguration without specialized tools. The device weighs 45 grams and mounts securely with the included wall bracket, supporting flexible placement in corridors, entryways, and auxiliary spaces.

Deployment Scenarios

Deploy the USL-MOTION as a distributed trigger point within multi-camera UniFi Protect deployments. Common use cases include motion-activated recording in areas with intermittent activity, integration with access control workflows, and supplementary detection in blind spots between fixed cameras. The low power consumption makes the sensor practical for temporary deployments or locations where hardwired power is unavailable.

Network Integration

The USL-MOTION integrates natively with UniFi Protect, eliminating third-party bridge devices or custom middleware. Motion events propagate to the Protect controller, triggering recording profiles, alerts, and automation rules defined within the application. All configuration and monitoring flows through the same web and mobile interfaces used for camera and access point management.

Installation Notes

The USL-MOTION (MPN: USL-MOTION) arrives with a wall mount bracket and CR123A battery installed. Mount the device at typical head height (1.5–2 meters) for effective motion coverage. The device holds FCC, IC, and CE certifications, and is NDAA compliant for government and critical infrastructure deployments. No special network preparation is required beyond standard UniFi Protect controller connectivity.

Jerry Tildsen, Senior Network Architect

"The USL-MOTION fits a practical gap in motion-triggered surveillance. Battery operation and minimal power draw make it ideal for retrofitting legacy spaces or temporary event monitoring without running new electrical circuits. Integrators often deploy it as a cost-effective auxiliary sensor alongside fixed camera arrays—it won't replace perimeter cameras, but it reliably generates motion events that feed into recording and alerting logic. The UniFi Protect native integration means no API wrestling or custom scripts; it's plug-and-configure."
