ICR
Use built-in photo sensor or manual to control ICR.
In case user selects manual mode, there are 4 modes: Night (On), Day (Off),
Auto or Schedule to control built-in IR LEDs. This function is very useful under
low illumination environment, even at 0 lux.
In case the Auto mode is selected, user needs to specify 3 parameters in
advance:
Night Mode Threshold (0~10000): this value sets the threshold to turn on IR
LED. It should be lower or equal to Day Mode Threshold.
Day Mode Threshold (0~10000): this value sets the threshold to turn off IR
LED. It should be higher or equal to Night Mode Threshold.
Delay Time: The delay time between LED On/Off switching.
The Current Value is the current luminance from the captured
video. It’s a useful reference to set LED On/Off Threshold.
LDC
LDC stands for Lens Distortion Correction. Adjust this value to correct barrel
distortion correspondingly.
3D De-Noise
3D De-Noise can remove or lower unwanted noise and preserve fine details
and edges.
