This recessed mount screws on the front part of AXIS F2105-RE Standard Sensor Unit and AXIS F2135-RE Fisheye Sensor Unit. It’s the perfect accessory when installing the selected sensor units on walls, glass, plastic, or metal panels from 1 to 15mm (0.04 in to 0.6 in). Beyond the stylish esthetics, it also guarantees that water won’t leak in the wall or the panel. This silver-colored mount is made from aluminum.
