510 Series Analog PTZ Camera
Gain Limit
This menu item limits the maximum user-configurable gain value
to avoid excessive image noise.
Defog
Enable the defog function if desired. This grants the camera
better visibility in foggy ambient conditions. It does not affect
condensation on the interior or exterior of the camera.
Init Lens
This triggers a lens initiation for basic maintenance purposes. If
you find that your image isn’t looking the way it used to, doing
this refreshes all electronic image adjustments and should restore
normal operation.
