Chapter 11 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 operation, which increases the reliability of the system.
A bidirectional connection shown in the figure below is required to be built between hot spare
video recorder(s) and working video recorders.
Note
● Up to 32 working devices and 32 hot spare devices are allowed.
● It is recommended to use all devices in a same model for compatibility. Contact your dealer for
details of models that support the hot spare function.
