Thanks again Dan,
I am working with Dan Maresca & Jessica to resolve recording issues on my SIP-EMVD-21-4R camera right now and will try to resolve that before moving forward with the audio problem.
Getting hard to keep track of just what changes I make to the camera, so try the one at a time.
Should have the switch online and both cameras running into Ethernet port 2 on the DVR pretty soon too, so can finalize this Topic about that problem with a report of how it works out.
Thank You again!
