1 Glossary
Note:
The glossary gives brief explanations to the basic operation
principle or the basic function of the camera. However, it doesn’t
mean the listed functions are all supported by the cameras
mentioned in this manual. Please take the function in the
corresponding specification as the standard.
Definition:
Definition is the degree to distinguish the edge between two parts.
Contrast:
Contrast is the color difference between the brightest and darkest
parts.
Saturation:
Saturation is the degree of color purity. The color is purer, the
image is brighter.
DAY/NIGHT Auto Switch:
The cameras deliver color images during the day. And as light
diminishes at night, the cameras switch to night mode and deliver
black and white images with high quality.
AGC:
AGC is a control circuit that automatically changes the gain of a
receiver or other pieces of equipment, so that the desired output
signal remains essentially. When under low illumination, AGC will
regulate the gain and amplification of the video signal.
