the effect of noise is less, and the image is clearer.
White Balance:
White balance can remove the unrealistic color casts. White
balance is the white rendition function of the camera to adjust the
color temperature according to the environment automatically.
BLC:
If you focus on an object against strong backlight, the object will
be too dark to be seen clearly. The BLC (Backlight Compensation)
function can compensate light to the object in the front to make it
clear, but this causes the over-exposure of the background where
the light is strong.

The SMART IR adopts the smart image processing technique to
automatically adjust the brightness curve by detecting multi-zone
brightness, and so as to prevent the over exposure of central point
existed in short IR distance conditions.

object can be detected and trigger alarm. The sensitive level can
be customized according to the environment.
