NOTE!
After the working mode is changed, the NVR will restart with some

For a working device that switches to a hot spare, some of its
functions will be unavailable, and some settings will be reset to
defaults.
If multiple working device fail at the same time with only one hot
spare device available, one working device gets backup at a time.
