Installing the Camera
Test your camera prior to selecting a permanent mounting location by
temporarily connecting the camera and cable to your DVR.
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:
1. Set the camera in the desired mounting position and mark
holes for screws through the camera base.
2. 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.
3. Mount the camera stand to the mounting surface using
the provided screws. Make sure all screws are fastened
tightly.
4. Adjust the camera as shown below:
A
A. 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°.
B. 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.
