Do Digital Video Recorders support audio and how does it work?
[Back to Top] Yes, most digital video recorders (DVR’s) support audio recording. It varies by manufacturer, and is sometimes optional, but most provide at least one audio channel and some will even provide an audio channel for every video channel. In most cases, you will need to add an audio microphone to the camera location and hook it up through the PC’s sound card or microphone input.
