Digital surveillance camera

摘要

A digital surveillance camera includes a video capture component, a data converter coupled to the video capture component and a signal transmission unit coupled to an output terminal of the data converter. The data converter processes the video signal with high frequency components from the video capture component in digital domain to generate the video signal in a specific format to be further transmitted in the digital serial differential form. The signal transmission unit transmits the signal via either an optical fiber or a cable with characteristics of long-distance transmission and lowers the resulting signal loss to ensure the quality of the received video signal.
