Description

Select ON to enable the defog function in poor weather conditions such as fog, smog or smoke. The

captured image can be improved.

This function is used to slightly calibrate the viewing angle when the focal length and focus

adjustment is completed. Select "DOWN" if your camera lens is facing down; select "UP" if your

camera lens is facing up.

Select AUTO to automatically enable IR LEDs at night or in the dark environment, or OFF to disable

this function.

This function is used to enhance IR LEDs performance for longer projection distance.

Note: It's not recommended to enable this function for a long time as it might impair the lifetime of IR LEDs

Select the level for IR light to activate. 0 ~ 20 . The higher the value, the more sensitive the IR light to

activate.

Set the delay time from 1 ~ 60 in second after which the day and night switch is made, or select 0 to

disable this function.

This is used for the environment where the light condition may change suddenly and usually last for a

short time, for example, the entrance of a parking lot. It may cause the day & night mode switching

constantly and damage the camera.

With this function, the camera will delay the mode switch at night since the light change is temporary

and unnecessary to pay attention.

Click to reset all camera settings to their default values. The camera will reboot to complete the reset

process.

Click to reboot the camera if necessary.
