(optional)
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 wall /
ceiling when mounted.
To install the camera:
1. Use the included mounting template to mark
holes for the screws. Drill holes for the
mounting screws.
NOTE: Insert the included drywall anchors if
you are installing the camera in drywall.
2. Feed the cable through the mounting surface
or cable notch and mount the camera stand to
the surface using the provided screws.
3. Use a Philips head screwdriver (not included)
to loosen the adjustment screw.
Installing the Camera Cable Extension Options
