3.1 VIDEO FORMAT

You can set the video format to 5 MP @ 20 fps, 4 MP @

30 fps, 4 MP @ 25 fps, 2 MP @ 30 fps, or 2 MP @ 25 fps.

3.2 EXPOSURE

3.2.1 EXPOSURE MODE

You can set the EXPOSURE MODE to GLOBAL, BLC, HLC,

WDR, or HLS.

GLOBAL

•

GLOBAL refers to the normal exposure mode, which

adjusts lighting distribution, variations, and non-

standard processing.

BLC (Backlight Compensation)

•

BLC (Backlight Compensation) compensates light to

the object in the front to make it clear, but this may

cause overexposure of the background where the

light is strong.

HLC (Highlight Compensation)

•

HLC stands for highlight compensation. The camera

detects strong spots (overexposed portions of

image), then reduces the brightness of the strong

spots to improve the overall image.

WDR (Wide Dynamic Range)

•

The wide dynamic range (WDR) function helps the

camera provide clear images even under backlight

circumstances. When there are both very bright and

very dark areas simultaneously in the field of view,

WDR balances the brightness level of the whole

image and provides clear images with details.

HLS (Highlight Suppression)

•

This is the same visual effect as a solar eclipse. If the

brightness of a part in the image exceeds the

threshold, this part will become black. Then the

whole image will be clear.

3.2.2 AGC (Auto Gain Control)

Optimizes image clarity in poor light conditions. The AGC

level can be set to HIGH, MEDIUM, or LOW.

NOTE:

Noise will be amplified when setting AGC level.

3.2.3 SLOW SHUTTER

SLOW SHUTTER increases the exposure time on a single

frame, which makes a camera more sensitive to the light

so it can produce images even in low lux conditions.

3.2.4 ANTI-BANDING

ANTI-BANDING prevents the appearance of horizontal

lines (banding) when photographing images in low

frequency light and high brightness environments.
