Slow Shutter
Slow Shutter can be enabled if the sensitivity is still not good enough under “High” gain condition at dark.
Optimal image level can be maintained by appropriate gain and shutter combination that determined
automatically inside the unit system. Slow Shutter can be selected from OFF, 1/30, 1/15, and 1/7.5. As slow
shutter activates, the exposure time becomes longer and frame rate becomes smaller, and moving objects
may result in blurred images.
