1. Mount the camera stand to the desired mounting
surface. Attach the camera to the supplied stand.

NOTE:

The camera can be mounted to either a wall or

a ceiling.

2. Aim the camera. Remove
the protective film from
the lens.

3. Connect the extension
cable to the camera.
Connect the other end of
the extension cable to the system.

NOTE:

Confirm that the arrows on the DIN extension
cable are aligned with the camera cable and system
ports when connecting the cable. If the pins in the DIN
connectors are bent, the camera will NOT function.

NOTE: Make sure the DIN connectors are firmly

connected and flush. A tight seal ensures
weatherproofing of the cable connectors.

mounting location by temporarily connecting the cameras and
cables to the system.
