Note: A grounding tab (P6) is provided on the PC board for those installations requiring a ground. The use of
the ground tab to earth ground is necessary to provide protection to the camera. A Faston (lug) is
provided in the accessory kit.
Heater Connections
The V910 has a heater in the base for those installations requiring it. Refer to Figure 1. The unit is delivered
with the heater connection made to the connector (P8) on the PC board. The heater requires 24 VAC. Refer
to Figure 5.
Camera/Lens Adjustments
After all cabling is complete, the camera and lens can be adjusted. The switch settings that follow refer to the
color and day/night versions. The day/night WDR camera is adjusted using a joystick control. Those
instructions follow.
Switch Settings
(Color and Day/Night Versions only)
There is a DIP switch on the camera board that allows the selection of: AE/ME (iris setting); ATW/AWB (white
balance setting); AGC (Automatic Gain Control ON or OFF); and BLC (Backlight Compensation ON or OFF).
The default settings on all cameras are: ME, ATW, AGC ON and BLC ON. ME setting is for DC autoiris and
AE setting is for fixed iris (all the cameras in this series have autoiris). Refer to Figures 7 and 8 for the
location and setting of the switches. To obtain the sharpest picture possible, the iris adjustment should be
made from a “full bright” setting down to an acceptable video level. This assures that the internal AGC of the
camera is not operational. See Table 3 for camera and lens specifications.
Lens/Autoiris Adjustment
The lens can be manually adjusted for focus and zoom. On the lens, focus [Near
∞
(Far)] is the front ring and
the zoom (Telephoto
Wide) is the back ring. Two video focus adjustment connectors are provided for use
with a portable/local monitor (cable provided in accessory kit) for making adjustment. One is on the PC board
on all the cameras. On the day/night and color cameras, a second connector is on the camera board; for the
WDR camera, a second connector is on the joystick control. Either connector can be used. Refer to Figures
5, 7 and 9. To make these adjustments, loosen the Zoom and Focus lever screws and turn the ring. When
adjustment is complete, retighten the screws. Focusing the lens may be impacted by the smoked lower
dome. After the camera/lens assembly is positioned as required, use the focus ring to adjust the lens to the
sharpest focus. Position the lower dome and check the focus. If it is acceptable, proceed to Final Installation.
If the lens is now out of focus, note the orientation of the dome (position on the 4 screws), as this must remain
constant throughout this procedure. Readjust the focus ring so the image is slightly out of focus and position
the lower dome in the same orientation as before. Repeat this procedure as necessary until the lens is
focused properly with the dome in position. Then proceed to Final Installation.
Note: When adjusting the focus, it is recommended that the iris be completely open (a dark condition, either
at night or using a filter) so that the depth of field does not influence the adjustment.
On autoiris lenses, iris adjustment may be required if the picture appears dark or grainy or has poor color.
There is a potentiometer on the day/night and color camera board to adjust the autoiris (for WDR cameras,
this adjustment is made from the OSD menu). Refer to Figure 7. Turning the potentiometer opens and closes
the iris to regulate light extremes. Turning the potentiometer clockwise opens the iris wider, allowing more
light.
