Capturing text insertions
The recorder supports Point-of-Sale (POS) and ATM text insertion via the UTC
ProBridge accessory connected to the RS-232 port on the recorder.
The feature is currently only available via the browser (see “Capturing text insertions”
on page 80).
Failover and recovery
You can set up a spare recorder to act as a slave unit (hot spare) for up to four master
TVN 21(
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 backup 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 can mix TVN 21 and TVN 21P units but you cannot include TVN 50s.
WARNING: Camera connected to the TVN 21S as PoE ports cannot be included in a
hot spare function.
