Chapter 19 Hot Spare Device Backup

Video recorders can form an N+M hot spare system. The system consists of several working video

recorders and at least one hot spare video recorder. When a working video recorder fails, the hot

spare video recorder would switch into operaon, which increases the reliability of the system. A

bidireconal connecon shown in the gure below is required to be built between hot spare video

recorder(s) and working video recorders.
