Auto Exposure and Auto Gain Control (AEC/AGC)
You can set the camera to automatic exposure control (AEC) to keep the same image
brightness during changing light conditions. You can enable both AEC and automatic gain
control (AGC) independently or together. Auto gain and auto exposure controls let you control
the range of exposure times and gain values used by placing minimum and maximum limits
on these parameters. When both AEC and AGC are enabled together, exposure times are
varied until the maximum exposure time limit is reached, then gain is applied.
Auto Exposure and Auto Gain Control are supported by all cameras except for POE-C2000 and
POE-C2400 models.
