Overview
The Ubiquiti USL-Motion is a battery-powered motion sensor for UniFi Protect deployments using Ubiquiti SuperLink wireless connectivity. It combines horizontal and vertical PIR sensing with tamper detection and is designed for flexible wall or corner installation.
The sensor communicates over Ubiquiti's proprietary SuperLink wireless technology and is managed through UniFi Protect. A SuperLink Gateway is required for operation. Ubiquiti specifies battery life of up to six years, depending on usage conditions.
Motion Detection
The USL-Motion uses separate horizontal and vertical PIR sensing modes for different mounting orientations. In horizontal orientation, the PIR sensor provides detection up to 1.5 m (4.9 ft). In vertical orientation, detection extends up to 6 m (19.7 ft), with pet immunity specified for this orientation.
SuperLink Connectivity
The motion sensor uses Ubiquiti's proprietary SuperLink wireless technology. The maximum specified SuperLink range is up to 2 km (1.2 mi) line of sight. Operating frequency depends on the regional version, with Ubiquiti specifying separate frequency ranges for the United States, European Union and Japan.
The SuperLink radio has a specified maximum transmit power of 14 dBm and antenna gain is not specified separately in the current official technical specification.
Power and Installation
The USL-Motion operates from a single CR123 lithium battery and has a supported voltage of 3V. Maximum power consumption is specified at 22.6 mW. The battery is replaceable.
The sensor can be mounted using adhesive or screws. The supplied mounting arrangement supports both wall and corner installation, with the physical dimensions varying according to the mounting configuration.
Key Features
- Proprietary SuperLink wireless connectivity with up to 2 km line-of-sight range
- Horizontal PIR detection up to 1.5 m and vertical PIR detection up to 6 m
- Up to six years of battery life with a CR123 lithium battery
- Tamper switch, function button and factory-reset button
- UniFi Protect management through web and mobile applications
Applications
The USL-Motion is intended for motion monitoring within UniFi Protect installations. It can be deployed in residential and commercial environments where SuperLink-connected motion detection is required, including locations where flexible wall or corner mounting is useful.
DC Supplies Product Note
The USL-Motion is not a standalone network sensor. Ubiquiti specifically identifies a SuperLink Gateway as a requirement for operation, so the gateway must be available in the deployment before planning the sensor installation. Regional SuperLink frequency specifications should also be checked when selecting the appropriate version for the installation location.

FAQs
Does the USL-Motion work without a SuperLink Gateway?
No. Ubiquiti specifies that a SuperLink Gateway is required for the USL-Motion.
What wireless technology does the USL-Motion use?
The sensor uses Ubiquiti's proprietary SuperLink wireless technology for communication with the compatible UniFi Protect infrastructure.
How far can the USL-Motion detect motion?
The detection range depends on the mounting orientation. The horizontal PIR sensor detects up to 1.5 m, while the vertical PIR sensor detects up to 6 m with pet immunity.
How long does the battery last?
Ubiquiti specifies battery life of up to six years. Actual battery life depends on operating conditions and sensor activity.
What battery does the USL-Motion use?
The sensor uses one CR123 lithium battery and operates at a supported voltage of 3V.
Can the sensor be mounted in a corner?
Yes. Ubiquiti specifies adhesive and screw mounting and provides dimensions for both wall-mounted and corner-mounted configurations.
