Adjusting the Video Image
Adjusting the Video Image
As part of the IP camera installation process, you make pan and tilt settings (and back focus settings if
necessary) for the camera in the dome. If you ever need to change these settings, follow these steps:
Procedure
Step 1 Remove the IP dome assembly by twisting the dome and trim ring assembly counter-clockwise and
pulling it away from the camera housing
Step 2 Remove the Privacy shield by squeezing it inward to release it from the four tabs that hold it into place.
Step 3 See Figure 2-4 and take these actions to adjust the camera lens to obtain the desired image:
Temporarily attach an analog monitor to the IP dome so that you can see video while adjusting the
camera. If the cable from the monitor terminates with a 3.5 mm jack, plug it into the analog video
output port on the IP dome. If the cable terminates with a BNC connector, connect it to the mini
cable with BNC adapter, then plug the cable into the analog video output port. The mini cable with
BNC adapter is included in the audio/video cables accessory kit, which you can purchase from Cisco
(Cisco part number CIVS-IPCA-1017=).
Make the following adjustments, viewing the video on the analog monitor as needed:
Rotation—The rotation is factory set and should not require adjustments. In the event that it
does need to be adjusted, turn the notched rotation wheel until you achieve the desired image.
Pan—Use a Phillips-head to loosen the panning lock screw (the one slightly recessed in a
cutout), then rotate the camera to obtain the desired image, then tighten the panning lock screw.
Tilt—Loosen the two tilt lock screws, adjust the lens to obtain the desired image, then tighten
the screws.
Back focus—The back focus is factory set for optimal use and should not require adjustments.
In the event that it does need to be adjusted, use the 0.9 mm Allen wrench that is supplied with
the IP camera to loosen the back focus hex screw, then adjust the back focus by aiming the IP
camera at an object that is at least 15 feet (4.5 meters) away and gently sliding the lens toward
or away from the camera. Take care not to pull the lens completely away from the camera.Obtain
a sharp picture in both wide-angle and telephoto positions. When the focus is set as desired, use
the Allen wrench to tighten the back focus hex screw.
Caution Do not manually adjust the focus or zoom for the IP camera. Attempting to manually do so may damage
the IP camera lens. Instead, use the Focus/Zoom window in the configuration software to remotely set
the focus and zoom for the IP camera.
