Overview
The Ubiquiti USL-Motion-3 is a three-pack of UniFi SuperLink wireless motion sensors designed for integration with the UniFi Protect ecosystem. Each sensor uses dual PIR sensing with separate horizontal and vertical detection zones and communicates using Ubiquiti's proprietary SuperLink wireless technology.
The sensors are battery powered and designed for flexible wall or corner installation using adhesive or screw mounting. Each unit uses a CR123A lithium battery and is specified for up to six years of battery life.
Motion Detection
The USL-Motion combines horizontal and vertical PIR sensing. The horizontal PIR sensor provides a detection range of up to 1.5 m, while the vertical PIR sensor provides detection up to 6 m and includes pet immunity. The vertical detection mode is intended to help distinguish smaller animals from the motion the sensor is intended to detect.
SuperLink Connectivity
Each sensor communicates over Ubiquiti's proprietary SuperLink wireless protocol. The specified maximum SuperLink range is up to 2 km under suitable conditions. The exact usable range depends on the installation environment and wireless conditions.
The sensor is designed for use with UniFi Protect. A compatible UniFi SuperLink Gateway is required for the sensor to communicate with the UniFi Protect ecosystem.
Installation and Power
The sensor supports adhesive and screw mounting and can be installed using wall or corner mounting configurations. Its compact enclosure and battery-powered design allow installation without a dedicated power cable at the sensor location.
Each sensor operates from a 3V CR123A lithium battery and has a maximum specified power consumption of 22.6 mW. Battery life is specified at up to six years.
Key Features
- Three UniFi SuperLink motion sensors supplied as one pack
- Dual PIR sensing with horizontal detection up to 1.5 m and vertical detection up to 6 m
- Pet immunity provided by the vertical PIR sensor
- Proprietary SuperLink wireless connectivity with a specified maximum range of up to 2 km
- CR123A battery operation with up to six years of specified battery life
Applications
The USL-Motion-3 can be deployed as part of a UniFi Protect security system where wireless motion detection is required. The three-sensor pack can be used to monitor multiple areas or provide motion coverage at several locations within a SuperLink-enabled installation.
DC Supplies Product Note
The USL-Motion-3 is a sensor pack rather than a standalone network endpoint. A compatible UniFi SuperLink Gateway is required for communication with UniFi Protect, so gateway availability should be considered when planning a deployment.
