1.4 Chief Introduction about Function
Motion Detection: In the surveillance area, the appearing motion object will trigger alarm. User can select
suitable sensitivity level with corresponding environment.
Color B/W auto switch: The camera will display color image and become monochrome automatically at night.
AGC: When object being shot look dim, please turn on AGC. It is propitious to enhance brightness. To output
standard video under different illumination, the range of auto gain control must be large enough. When under low
illumination, AGC will increase camera’s sensitivity, and output bright and clear video.
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 more spotless.
