Whichever power method you’re using with your Multi Sensor, you can keep on using it in the recessed mount.
The mount has been designed to allow for each sensor’s batteries to still easily be changed, or for the Multi Sensor’s optional power cable to be used if you prefer to power your sensor without batteries.
Drill a 75mm hole in the location you want to mount your sensor
Lock the Multi Sensor into the mount
Carefully insert the mounted sensor into the prepared hole
Adjust the gimble so the sensor is properly positioned
