condition. Web client provides the following methods to increase image brightness and
ensure surveillance quality.

and drag the slide bar of brightness.
Longer Time
of Shutter
Camera shutter time means the cycle of the sensor calculating light input amount.
Therefore, the longer the shutter is, the brighter the image will be.
Notice:
1) If the target object is moving fast, this method is not applicable.
2) Go to
Settings > Camera > Image > Exposure
, user can set Shutter Mode (Auto/
Manual) and Shutter Lower Threshold or Shutter Level.
Increase Gain
Camera gain means photo-sensibility, the sensitivity level of a sensor to light. A high gain
requires less light exposure for low light condition.
Notice: However, the higher
the gain is, the more noise points there will be and the
worse the image will be. Auto mode is suggested. Apply
default values, or select “Auto”
and set Gain Upper Threshold in
Settings > Camera > Image > Exposure
. If selecting
“Manual”, drag the slide bar to adjust gain level.
