SuperLink Motion Sensor

The Ubiquiti UniFi Protect SuperLink Motion Sensor (USL-Motion) is a battery-powered smart sensor designed for versatile indoor installation. It connects to the UniFi Protect ecosystem via the proprietary SuperLink wireless protocol. The device weighs 45 g and includes adhesive and screw mounting options for flexible placement.

SuperLink Wireless Constraints

The sensor operates on the 915.6927.6 MHz frequency band with a maximum transmit power of 14 dBm and an antenna gain of 1 dBi. This proprietary link supports a maximum range of up to 1.2 mi (2 km) line-of-sight to a compatible SuperLink gateway. Actual range will vary significantly based on building materials and interference.

Dual PIR Detection Zones

The unit features two passive infrared sensors with distinct detection patterns. A horizontal sensor covers up to 1.5 m (4.9 ft), while a vertical sensor extends up to 6 m (19.7 ft) and includes pet immunity to reduce false alerts. Buyers needing longer detection distances or outdoor-rated hardware should consider other solutions.

Questions about this item

Should I choose the adhesive or screw mount for the SuperLink motion sensor?

Both adhesive and screw mounting options are included; use adhesive for quick placement on smooth surfaces and screws for a more permanent fix.

What does the 14 dBm maximum transmit power mean for daily operation?

The 14 dBm output supports the proprietary SuperLink link budget, enabling up to 1.2 mi range to the UniFi Protect gateway under clear conditions.

How does the 915.6927.6 MHz SuperLink frequency affect sensor placement?

Operating at 915.6927.6 MHz, the proprietary SuperLink protocol penetrates walls better than higher bands, so the sensor can be placed up to 2 km from the gateway with the 1 dBi antenna.
