Hot Spare
You can set up a spare recorder to act as a slave unit (hot spare) for up to four TVN
22(S/P) master units. This slave unit will continually monitor the master units and if one
of the master units should fail, it can then take over recording until the failed unit comes
back online. Once the failed unit is back operating normally again, the slave unit will
send its recordings to the HDDs of the recovered unit so that no recordings are missing.
The hot spare unit can only back up one master unit at a time. If more than one unit
should fail, the hot spare unit will only backup the unit that failed first.
All units must have the same number of channels.
You cannot mix TVN 22 and TVN 22P units.
WARNING: Camera connected to the TVN 22S as PoE ports cannot be included in a
hot spare function.
In order to have the failover functionality working properly, the following points must be
taken into account:
• A stable network connection is required
• There must be at least 10 Mbps of unallocated bandwidth available with the main
recorder. The main and failover recorders must have equal camera counts
• Ideally the failover recorder must have equal storage capacity to the main recorder
to accommodate for long outage times of the main recorder.
To set up a hot spare recorder:
1. From the menu toolbar, click Recording > Hot Spare.
2. First set up the master recorders.
For each master recorder, check the Normal Mode box and Enable. Enter the IP
address and password for each recorder.
