IR Check Function: Note this option is only available for Box
Camera (except GV-BX2600). This function determines whether the
surveillance area is illuminated by an externally installed infrared
illuminator.
Off: The default setting. The infrared illuminator will be constantly
off. It is advisable to enable this option when the color temperature
of outdoor lighting is 6000 K or above.
On: The infrared illuminator will be constantly on.
Trigger by Input / Trigger IR by D/N: Select this option for the
infrared illuminator to turn on under low light and turn off under
sufficient light.
Note:
1. If an infrared illuminator is installed for outdoor surveillance, it is
suggested to use the Trigger by Input or the Trigger IR by D/N
function to avoid incorrect judgment of lighting and hence the action
of the IR cut filter. See Infrared Illuminators in the Hardware
Manual.
2. If you select Trigger by Input / Trigger IR by D/N option, make
sure you have set D/N as Auto and configured its sensitivity level.
Iris Type: Note this function is not supported for the camera with fixed
lens or fixed iris. This field shows the iris type (DC-Iris or P-Iris) of
your GV-IP Camera.
Auto Iris: The option is designed for auto iris lens (DC-Iris or P-
Iris). Enable the auto iris function when the scene appears fuzzy
and the Flicker Less function does not help to improve the
situation.
BLC: Note this function is not supported by GV-BX2600. Select On to
enable Backlight Compensation (BLC). This function is used to adjust
the color intensity of scenes with strong light at the background.
