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 re-  
maining 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.  
Table A. Recommended Wire Gauge and Wiring Distances  
The following are the recommended maximum distances for 24 VAC applications and are calculated with a 10-  
percent voltage drop. (Ten percent is generally the maximum allowable voltage drop for AC-powered devices.)

LENS SETUP AND FOCUS PROCEDURES  
Video Drive Auto Iris Lens  
Set the lens mode selector switch to AIV. Switch the ESC and AGC OFF. Refer to the lens instructions and  
adjust the lens for the optimum picture (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. 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 Ad-  
justment section) and focus on the selected scene. Remove the ND filter and set the lens focus as required.  
Set the AGC switch to ON, as required. Most scenes benefit from AGC.  
Direct Drive (DC) Auto Iris Lens  
Set the lens mode selector switch to AID (default setting). Switch the ESC and AGC OFF. Use an appro-  
priate screwdriver to turn the lens level potentiometer (refer to Figure 1) fully clockwise. Next, slowly  
adjust the potentiometer counterclockwise 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. When finished, switch  
the ESC and AGC ON.  
Fixed Lens - No Iris  
Set the ESC and AGC switches ON (default settings). To focus, set the lens focus to infinity and 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). Set the lens focus as required.  
Manual Iris Lens  
Set the ESC and AGC switches ON (default settings). 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 adjust-  
ment ring (refer to the Back Focus Adjustment section). Adjust the lens focus, set the iris (if equipped) for  
the best picture quality. The largest aperture gives the best light sensitivity, 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, outdoors, use an ND3 filter.  
BACK FOCUS ADJUSTMENT  
The back focus adjustment is located at the front of the camera and is accessible from either side of the case  
To adjust the back focus:  
.
1. Loosen the two back focus lock-  
COUNTERCLOCKWISE  
ing screws (one on each side).  
2. Turn the back focus ring until the  
object is in focus.

NOTE: Under most conditions, no setting of switches will be required. Please read the details of each  
switch before making any adjustments.  
1 BLC - Back Light Compensation  
OFF (Default setting) - Disables the BLC mode.  
BLC - Enables the BLC mode. If a bright backlight is present, the objects in the picture may appear  
dark or as a silhouette. BLC enhances objects in the center of the picture, and can be used to  
improve picture quality; in a fixed scene.  
2 AGC - Automatic Gain Control  
OFF - Disables the AGC mode.  
AGC (Default setting) - Enables the AGC mode. Automatically adjusts the image to compensate  
for changes in light levels. Most scenes benefit from AGC operation.  
3 OPT - Optima  
OFF (Default setting)  
OPT - Boosts the video by 3 dB. Only use if your video signal appears weak on your monitor.  
4 ESC - Electronic Shutter Control  
OFF - Disables the ESC mode.  
ESC (Default setting) - Enables the ESC mode. The ESC function automatically changes the sensi-  
tivity of the camera by varying the electronic shutter speed according to the amount of incident light.  
Electronic shutter speed range is 1/60 to 1/100,000. Should only be used with an AID or manual iris  
lenses. Do not use with an AIV type lens.  
5 AIV/AID - Auto Iris Lens Mode Selector  
The switch setting is determined by the type of lens used:  
AIV - Video controlled Auto Iris lens. Disable the ESC mode when using an AIV type lens.  
AID (Default setting) - DC controlled Auto Iris lens.  
6 INT/LL - Internal/Line Lock  
Line Lock (LL) (Default setting) - Locks the vertical frame to the power supply frequency.  
Eliminates vertical roll caused by multiple cameras connected to the same switching device.  
Internal - Locks the vertical frame to the internal oscillator. Use with DC or unstable AC.  
NOTE: If DC power is applied when the INT/LL switch is in the LL position, the camera will not  
function. Switch the mode to INT.

Pelco Manual C1937M-C (4/03)  
 
7 NOR/SHP - Sharpness  
NOR (Default setting) - Sets the camera to normal sharpness mode.  
SHP - Enables the Sharpness mode. Enhances picture detail by increasing the aperture gain of the  
camera, sharpening the edges in the picture. In some scenes, the SHP mode will increase edge  
noise on your monitor.  
8 LC - Long Line Compensation  
OFF (Default setting) - Disables the Long Line Compensation mode.  
LC - Enables the Long Line Compensation mode. Boosts the video drive level to 1.25 Vp-p for long  
line transmission. Use only if your wiring is causing video signal deterioration.  
9 EDR - Extended Dynamic Range  
OFF (Default setting) - Disables the EDR mode.  
EDR - Enables the EDR mode to help balance a scene with a large dynamic range. Use this  
feature to improve the picture in washed-out areas. This feature adds 12X the dynamic range, but  
also increases dark area picture noise. See page 10 for further details.  
10 AW1/AW2 - Automatic White Balance  
AW1 (Default Setting) - Automatically processes the viewed image to retain color balance over a  
wide color temperature range.  
AW2 - Processes the viewed image to retain color balance in a restricted color temperature range.  
Use only when AW1 causes an unbalanced color picture.

CAMERA SYNCHRONIZATION (AC OPERATION ONLY)  
When using more than one camera power supply, a brief vertical roll may occur on the monitor when a  
camera view is switched. To eliminate vertical roll, adjust the phase control by synchronizing, or line-lock-  
ing, the cameras to one another. Use the phase potentiometer located on the side of the camera (refer to  
Figure 1) 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).  
DYNAMIC RANGE AND THE EDR (EXTENDED DYNAMIC  
RANGE) FEATURE  
Dynamic range is the ratio between the brightest and darkest parts of an image or scene. A scene that  
ranges from bright sunlight to deep shadows is said to have a high dynamic range, while indoor scenes  
with less contrast will have a low dynamic range.  
The EDR feature will help capture the entire range of the scene. A 12 times improvement in dynamic  
range can be achieved with this feature. In scenes with very high dynamic range, the EDR feature will  
exhibit a higher noise level than when the feature is turned off. This is normal, and not a mal-function.  
NOTE: Depending on the scene contrast, it may or may not be possible to capture the entire range  
with any camera. Careful camera placement should be considered in extreme cases.
