If your Motion Sensor Gen 2 is not detecting motion, it’s likely the result of the placement of the Sensor itself.

We recommend mounting the Motion Sensor Gen 2 in the corner of your room. For optimal performance, the sensor must be mounted 6 feet from the ground. This ensures proper coverage throughout the room. The Motion Sensor Gen 2 has a 90-degree field of view, and can see outwards 35 feet. You can also mount the Motion Sensor Gen 2 to a flat wall. If opting for this, note that the Sensor will only capture the 90 degrees out from its center, meaning that 45 degrees on either side will not be captured.

If you are placing the Motion Sensor Gen 2 on a flat surface rather than mounting it, we recommend having it as close to the edge of the surface as possible.

Once you have made any changes to your Motion Sensor Gen 2, you can then begin to test the sensor.
