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):

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

Camera 2 and Monitor 2 sockets
are used only with optional
additional monitor and camera.
Installing a Second Monitor:
6. Plug the AC Power Adapter’s cable into the
“Power” socket on the back of the monitor.
7. Run the wires going to the camera under the
plastic hooks on the back of the monitor so
that any tension on them will not be directly
transferred to the plugs or sockets.
8. Plug the AC power adapter into a 120VAC
socket.
9. Test the monitor and camera unit by pressing
the camera button. The image in front of the
camera should be displayed clearly.

the back of the secondary monitor.
12. Follow steps 6-9 above to complete the
installation

4. Using the 4 included screws and 4 screw anchors,
attach the camera mounting bracket to the wall (see
Figure 4).
5. Connect the wires coming from the monitor to the
proper terminals E1 thorough E4 on the back of the
camera (see Figure 5).
6. If the Door Phone will control a locking device,
connect the wires coming from the locking device to
the relay output terminals K1 and K2 on the back of
the camera (see the Sample Application on page
11).
7. Set the desired camera angle up and down by
moving the tilt adjustment in the opposite direction.
8. Push the tab on top of the camera into the top of the
bracket. Make sure that no wires are preventing the
camera from seating properly in the bracket. Pull the
slide-out cover to expose the hidden screw location.
9. Secure the camera to the mounting bracket with the
included camera screw. Close the cover at the
bottom of the camera to conceal the camera screw.
1. Position the camera so the area to be monitored is
easily visible, typically 5 feet (150cm) above the
ground (see Figure 3). Do not position the camera in
direct sunlight or where it will be exposed directly to
rain or snow.
2. Cut a hole large enough to run the 22AWG
4-conductor wire through the wall to where the
camera unit is to be mounted. If using a locking
device, the wires used to control the device must
also be run through this hole.
3. Run the 22AWG 4-conductor wire from the camera
location to where the monitor is mounted. The
maximum wiring distance is 165’ (50m) (see Wiring
Diagram, page 8).
