Part Number
Description
CIVS-IPC-2421
Indoor Dome, Smoked, Lens 2.8–10 mm
Problem Description
Camera focus without the dome present is sharp and clear. When the smoked dome is fitted over the camera to
obfuscate the lens position, the image loses some sharpness and becomes noticeably softer. This problem is not
seen when the smoked dome is removed.
Workaround/Solution
Adjustments for both focus and focal length of the lens should be done with the smoked dome positioned in front of
the lens. Remove the smoked dome and hold it in front of the lens while making adjustments. If the tether on the
attached smoked dome is too short and prevents it from being positioned in front of the lens, a spare smoked dome
should be used instead.
