I was wondering if someone in the group has used a RPDVR4K 250GB HDD DVR FOR SECURITY CAMERA RECORDING. Radio Parts Group is selling this.
I would like to know if it records audio.
And if the unit can be set up to sequentially show a full screen view from each camera or a fixed screen showing all 4 cameras.
If sequential view is possible. how long is each camera view shown before showing the next?
