To connect the camera power and video:
1. Remove the cosmetic trim ring from the camera (refer to Figure 1). Thread cabling through the rear
cover.
2. Connect the power cable to the two pin power connector on the back of the camera using the terminal
block connector (provided). Refer to Table A for the recommend wire gauge and wiring distances.
3. Connect a video cable to the SIGNAL OUT connector (BNC) on the back of the camera. Refer to
Table B for the type of video coaxial cable to use.

AC Operation Only – If you are wiring more than one camera to the same transformer, connect one side
of the transformer to the same terminal on all cameras, and connect the other side of the transformer to
the remaining terminal on all cameras. Failure to connect all of the cameras the same way will cause the
cameras to be out of phase with each other and may produce a vertical roll when switching between
cameras.

LENS SETUP AND FOCUS PROCEDURES
Video Drive Auto Iris Lens
When a video drive auto iris lens is used, the lens mode selector switch must be set to AIV. Switch the
ESC and AGC OFF. Refer to the lens instructions and adjust the lens for the optimum picture (video out-
put level of 1V peak-to-peak). Switch the AGC ON. To focus, fully open the iris by covering the lens with a
suitable neutral density (ND*) filter. Set the lens focus to infinity (far). Select the scene to be viewed.
Use the back focus adjustment ring (refer to the Back Focus Adjustment section) to focus on the selected
scene. Remove the ND filter and set the lens focus as required.
Direct Drive (DC) Auto Iris Lens
Set the lens mode selector switch to AID. Switch the ESC ON. Use an appropriate screwdriver to turn the
lens level potentiometer (refer to Figure 1) fully clockwise. Next, slowly adjust the potentiometer counter-
clockwise until the optimum picture is obtained (video output level of 1V peak-to-peak). To focus, fully
open the iris by covering the lens with a suitable neutral density (ND*) filter. Select the scene to be
viewed. If the viewed scene is 6.5 feet (2 m) away or farther, set the lens focus to infinity (far). Use the
back focus adjustment ring (refer to the Back Focus Adjustment section) and focus on the selected
scene. Remove the ND filter and set the lens focus as required.
Fixed Lens
To focus, set the lens focus to infinity and view an image greater than 6.5 feet (2 m) away. Focus the im-
age with the back focus adjustment ring (refer to the Back Focus Adjustment section). Set the lens focus
as required.
Manual Iris Lens
To focus, open the iris fully and set the lens focus to infinity. View an image greater than 6.5 feet (2 m)
away. Focus the image with the back focus adjustment ring (refer to the Back Focus Adjustment section).
Adjust the lens focus, set the iris for the best picture quality. The largest aperture gives the best light sen-
sitivity, the smallest aperture the greatest depth of field.
Zoom Lens
Set the lens focus to infinity (far) and fully open the iris by covering the lens with a suitable neutral density
(ND*) filter. Zoom out to the widest field of vision and view a distant object. Adjust the back focus adjust-
ment ring until the object is in focus (refer to the Back Focus Adjustment section). Next, zoom fully in and
adjust the lens focus until the object is again focused. Repeat these steps until the full zoom range may
be viewed with the minimum loss of focus.
*NOTE: For best results in outdoor lighting situations use an ND3 filter to focus the camera.

CAMERA SYNCHRONIZATION (AC OPERATION ONLY)
When using more than one camera power supply, a brief vertical roll may occur on the monitor each time
a camera view is switched. To eliminate vertical roll, adjust the phase control by synchronizing, or line-
locking, the cameras to one another. Use the phase potentiometer located on the side of the camera to
make adjustments.
It may be necessary to have two people in communication when synchronizing the cameras: one person
at the camera and another person at the monitor to observe the vertical roll and the effect of any adjust-
ments made at the camera.
To synchronize the cameras do the following:
1. Choose a reference camera to which all other cameras will be phased.
2. Select a camera and synchronize it to the reference camera by turning the phase adjustment control
clockwise and/or counterclockwise.
3. Each time an adjustment is made, switch back and forth between the camera you are adjusting and
the reference camera. Repeat this process as many times as necessary, until the roll between the
cameras is no longer noticeable.
4. Adjust the phase of all other cameras by repeating steps 2 through 3. Always adjust to the reference
camera selected in step 1.
NOTE: The preferred method for camera phase adjustment is to use a dual trace oscilloscope to align
the vertical sync pulses of the reference camera to the selected camera(s).
