in a specific area. It is activated only in a low illumination environment to minimize the effects
of glare from bright lights such as spotlights, street lights or headlights in the field of view.
Select a level for the HLC. The higher the value, the more the highlight compensation.
3D-DNR Settings: This limits the amount of digital “video noise” that is usually found in any video
stream, and helps to reduce file size. The higher the level, the more the reduction.
Select ON to force on the 3D-DNR function when the selected level (the field below) is achieved; Off
to disable the 3D-DNR function; Auto to automatically turn on / off or adjust the level for the 3D-DNR
function. Select a level for the 3D-DNR. The higher the level, the more the reduction.
D-WDR Setting: This feature provides clearer images when both of the very bright and dark areas
simultaneously appear on the camera view. Four options are included: off, low, middle and high.
White Balance Settings: Select the mode that delivers the best quality image for the camera’s light
environment. You can click the Push button on the right side to instruct the camera to the selected
mode. This is like a “semi-automatic” way to adjust the White Balance mode to suit the user.
