ENFORCER VIDEO DOOR PHONE

Installation Notes:

1. Unpack the video door phone and note the included parts.

2. Read this manual thoroughly. A clear understanding of the manual will make installation

and operation much easier.

3. Find a good location to mount the monitor and camera. Make sure there is enough room

to wire both units correctly with 22AWG 4-conductor wire.

4. Use only untwisted-pair wire; twisted-pair wire may cause interference.

5. Avoid mounting either the cameras or the monitors near sources of strong

electromagnetic signals or other electronic devices as they may cause interference.

6. Avoid mounting the cameras in direct sunlight or exposing the camera to strong vibrations

or direct rain or other moisture, as it may damage them.

7. The camera and the monitor contain no user-serviceable parts. Opening them may

damage sensitive components and void the warranty.

1. The monitor must be positioned so that the image

can be seen clearly and the user can operate the
monitor’s functions.

2. Use the mounting bracket as a template to pencil

in where to drill the holes for the mounting bracket
screws.

3. Drill the mounting bracket holes as needed. Drill a

hole large enough to fit the 22AWG 4-conductor
wire which will run through the wall from the
camera to the monitor (see Figure 1).

4. Using the 4 included screws and 4 screw anchors,

attach the monitor bracket to the wall, running the
cable through the large hole in the mounting
bracket.

5. Plug the brown 4-pin plastic connector from the

camera into the “Camera 1” socket (see Figure 2).

NOTE: If using only one monitor and camera,

there will be unused sockets on the back of the
monitor.

Installation (monitor):

Mounting Bracket

Mounting bracket holes

Drill a hole in this shaded area large
enough to run 22AWG 4-conductor
wire to the camera and an additional

monitor or camera.
