Third, improve the indoor light illumination, select the cameras with BLC function
By increasing the illumination of the indoor light is another way to reduce the backlight phenomenon.Backlight phenomenon is mainly caused by strong contrast of light intensity in field of view.Cameras installed in the entrance,usually with strong outdoor light and weak indoor light, In this way, if increasing the illumination of indoor light,reduce the contrast with the outside light,can reduce the backlight phenomenon.Some cameras also support BLC(backlight compensation function) function,turn on BLC function,also can help to solve backlight problem.Below is the BLC function of our 4MP AHD Camera for your reference.
