INSTALLATION
The lens must be either a C- or CS-mount type of less than 2.2 pounds (1 kg). The protrusion behind the mounting surface must be within the limits as shown in Figure 3.
The camera is supplied with a lens connector for inserting the power and control cable of
an auto iris lens. Before connecting an auto iris lens, however, you first have to replace the
lens cable plug with the one supplied with this camera. To replace the plug:
a. Detach the old plug from the lens cable.
b. Solder the wires to the pins of the new plug (refer to Figure 4). For cable pin as-

3. Screw in the lens, and turn it until it is secure.
4. Insert the lens plug in the LENS connector. Skip this step if you are installing a manual
iris lens.
5. Mount the camera.

7. Connect the camera to a 24 VAC, 60 Hz, Class 2 power supply.
Pelco Manual C1905M (10/99) 5
BACKFOCUS ADJUSTMENT
1. Set the CCD-IRIS switch on the rear of the camera OFF.
2. Set the iris wide open and the focus on infinity or a distant object. If you have an auto
iris lens, use a neutral density filter or other means to decrease the amount of light so
that the iris will open as wide as possible.
3. Turn the focal length adjustment ring for the best picture.
4. If you have a zoom lens, zoom to a close object and adjust the lens controller or focus
for the best picture. Repeat steps 2-4 until the lens remains in focus throughout the
zoom range.
5. If you have a lens with a manual iris, set the CCD-IRIS switch ON.
VERTICAL PHASE ADJUSTMENT
The vertical phase adjustment is used only when using more than one camera. If cameras
are not synchronized to the AC line, switching between cameras may produce what appears to be roll on the monitor.
To adjust the vertical phase, turn the V-PHASE screw on the rear of the camera (while
switching as rapidly as possible between two camera views) until the switching is clean and
there is no vertical roll or flip.
INCIDENT LIGHT LEVEL ADJUSTMENT
If the picture is too dark or if the picture’s highlights are extremely overexposed, adjust the
LEVEL adjustment on the rear of the camera. The adjustment can only be used for a
manual iris lens (CCD-IRIS switch is ON) or DC-controlled auto iris lens.
1. Turn toward L (low) to make the picture darker.
2. Turn toward H (high) to make the picture brighter.
BACKLIGHT CONTROL ADJUSTMENT
You can compensate for backlight conditions by turning the BLC (Backlight Control) adjustment screw on the rear of the camera. When using this unit under backlight conditions, turn
the BLC adjustment screw toward AV. The adjustment can only be used for a manual iris
lens (CCD-IRIS switch is ON) or DC-controlled auto iris lens.
TROUBLESHOOTING
The following conditions may be observed and are not necessarily a fault of the camera.
Vertical smear
This may occur when viewing a bright object or an intense reflection.
Patterned noise
A fixed pattern may appear over the entire monitor screen when the camera is operated at
a high temperature.
Jagged picture
This becomes noticeable when viewing stripes, straight lines, or similar patterns.
