Adjusting the Lenses
Once all cables are connected to the video
surveillance system, you may need to adjust the
lenses on the cameras. Because the cameras are
installed away from the monitor, you will need a
second person to help with this job: one person to
watch the monitor, and one person to adjust the
lens.
The variable focus lens provides three types of
adjustments:
Focus: Near (N) to Infinity ( )
Focal Length: Telephoto (T) to Wide Angle (W)
Iris: Close to Open
The following illustration identifies the locations of
the adjustment rings on the lens.

To adjust the lens settings:
1. Adjust the Focal Length.
Turn the ring towards W (wide angle) to use a
longer focal length.
Turn the ring towards T (telephoto) to use a
shorter focal length.
2. Adjust the Focus.
Turn the ring towards N (near) to adjust the
focus to close objects.
Turn the ring towards
focus to distant objects.
3. If the image seems too dark or too bright, adjust
the Iris.
Turn the ring towards Close to make the
image appear dimmer (darker).
Turn the ring towards Open to make the
image appear brighter (lighter).

Video Does Not Appear on
Monitor
1. Make sure that the monitor is plugged in and
powered on. (The monitor light is on.)
2. Make sure that the monitor cable is connected
to the Monitor port on the Quad Splitter and
Video In port on the monitor.
3. Make sure that video cables from the cameras
are securely connected to the Camera In ports
on the Quad Splitter and Video ports on the
cameras. Refer to Figure 1 for wiring
information.
4. Make sure that power has been applied to the
cameras. The power light is located on the
back of the cameras.
5. If video appears from some cameras but not
others, try switching cable connections.
Unplug a camera that is working and plug in
one that it is not working into the working
Camera In port. If the camera works, there
may be a problem with the original "Camera
In" port. Try connecting a working camera
into the suspected bad port. If this camera
does not work, contact customer support for
instructions.
If the camera does not work, check the cable
for damage. If the cable appears
undamaged, verify that the power is
connected and applied to the camera. If
power is OK, you may have a bad camera.
Contact customer support for instructions.
If none of these procedures work, contact
customer support for instructions.
