Before Installing the Camera
![]()
- Decide whether to run the cables through the wall / ceiling (drilling required) or along the wall / ceiling.
- If you run the cables along the wall / ceiling, you must run the cable through the cable notch on the base. This will keep the camera base flush to the surface when mounted.
To install your camera:
- Set the camera in the desired mounting position and mark holes for screws through the camera base.
- Drill the holes, then feed the cable through the mounting surface or cable notch.
NOTE: Insert the included drywall anchors if you are mounting the camera onto drywall. - Mount the camera stand to the mounting surface using the provided screws. Make sure all screws are fastened tightly.
- Adjust the camera as shown below:
- ROTATING THE ARM: Rotate the arm until you hear an audible click. Each rotation or click locks the arm into that position. The arm of the camera can be rotated up to 360°.
- BENDING THE ARM AND LEVELING THE CAMERA: Use a Phillips head screwdriver (not included) to loosen the adjustment screw. Bend the arm of the camera up to 90°, and rotate the camera until it is level with the viewing area, then tighten the screw.
- Remove the vinyl film from the camera lens when your installation is complete.
