Surveillance System Terminology
Surveillance System Terminology Electronics,Science & Technology We present you with the surveillance system terminology in a brief and concise manner. AES Automatic Electronic Shutter: It automatically adjusts the shutter speed against the changing brightness levels to get the best possible signal output. High Brightness Levels ->> Increased Shutter Speed Low Brightness Levels ->> Decreased Shutter Speed AGC Automatic Gain Control: Also known as ‘Automatic Voltage Gain’, it boosts the output signal level, regardless of the variation of amplitude in an input signal. The amplification of the signal is achieved with a closed-loop feedback circuit. Back Light Compensation It shifts the camera focus from the center of the picture to the sides of the picture. This is advantageous in situations where the light source is at the back of the subject; otherwise, the subject would be a big black spot. CCTV Closed Circuit Television: Customary television primarily used ...
