y BLC (Back Light Compensation)
Under severe bright “back light” conditions, the target object will show dark, which hides
object detail. Set this switch to “ON” for compensation for this phenomenon. The target
object should appear with more detail after enabling this setting.
y AGC (Automatic Gain Control)
Set this switch to “ON” to enable this automatic video gain adjustment. Under
severe/excessive illumination conditions, the camera video may saturate. Enabling this
feature will automatically lower the video amplifier gain, improving video quality. This
setting also compensates for low light conditions. If the camera is subject to under
exposure, or overly dark illumination conditions, the camera will automatically increase
video amplifier gain, improving video quality.
