Description

 Digital camera with built-in audio Technical field

 The invention particularly relates to a digital camera device with built-in audio.

Background technique

With the development of computer multimedia technology, digital video compression coding technology is becoming more and more mature, so computers are widely used in the field of surveillance. It generally adopts the following structure: at the front-end monitoring site, there are several cameras connected to the monitoring terminal through corresponding lines, and the monitoring terminal can be one. PC The machine can also be a dedicated industrial computer. In addition to processing the video signal transmitted by the camera, the monitoring terminal can also use the video compression card and the communication interface card to transmit the signals to one or more monitoring centers for centralized processing by using the communication network. based on PC The monitoring system has strong functions and high flexibility. It can take advantage of the powerful processing functions of modern computers, but its stability is general. In addition, its software is not open enough, it is difficult to directly expand the system, and the cost is very expensive.
