will regulate the gain and amplification of the video signal.
S/N ratio:
It is the ratio of Signal voltage and noise voltage. The ratio is larger, the effect of noise is
less, and the image is clearer.
OSD (On Screen Display):
The on-screen display (abbreviated OSD) is an image superimposed on a
screen picture, used for displaying information and menu.
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.
ICR Auto Switch:
The infrared cut filter can block infrared light during the daytime. For ensuring a
high sensitivity and clear image, the infrared cut filter will be replaced by normal filter at night to let
the infrared light in.
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.
BLC OFF
BLC ON
EIS (Electronic Image Stabilization):
Electronic image stabilization function can reduce certain
ranges of vibration which is caused by the external environment.
3D Digital Noise Reduction:
Comparing with the general 2D digital noise reduction, the 3D digital
noise reduction function processes the noise initiated by CCD besides processing the noise in the
separated Y video signal and C video signal.
