Chapter 2 Getting Started
Installing the Cisco Video Surveillance 2621 IP Dome
–
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 three back focus hex screws, 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 three back focus hex screws.
–
Pan—Use a Phillips-head to loosen the panning lock screw, 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.
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.
Step 11 Replace the privacy shield by squeezing it to fit inside the four tabs on the camera unit (see Figure 2-5).
Make sure to adjust the privacy shield inside the dome and trim ring assembly so that it does not block
the lens from capturing video.
