jfsoto1988 0 Posted May 1, 2018 Am I suppose to connect the RCA (DVR Side) to Audio Out with a BNC adapter? The camera that has the microphone connected is on Ch5, which I connect the RCA to RCA Audio In Ch5, but there is no sound. The DVR has a volume setting & I have the display through VGA on my large plasma flat screen TV. Is the RCA supposed to be connected to the AV connections of TV?
