Dvr monitor the video recorder without image output is what the problem
If the format is only the system disk, then the system, monitoring software must be reloaded, set; VCR is the embedded host, format only to clear the video data, the system program and settings are stored in the motherboard chip So there is no need to reset it.
What show? Is the connection right? Machines and connections are no problem, that is, the connection and display and video recorder display mode no election.
