Setup Diagram
Before installing the cameras:
• 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 the cameras:
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
installing the camera in drywall.
3. Mount the camera stand to the surface using the
provided screws. Make sure all screws are fastened
tightly.
Installing the Cameras Cable Extension Options
Extend the cable run for your camera depending on the cable type
used. Additional extension cables sold separately. See table below:

Notes:
1. The extension cable must be a single stretch of cable between the DVR
and camera. You cannot connect multiple extension cables to each other.
2. For cable runs above 300ft / 92m (option 3), you must connect the
power adapter directly to the camera, rather than at the end of the
extension cable.
3. Indicators that your cable run may be too long:
• Video is permanently black & white (even during day time)
• Video is unclear, soft, or distorted
