NVR Failover

214 VideoEdge NVR 4.4 Installation and User Manual

When you add a secondary NVR to victor unified client as a recorder, you should add it by a static

IP address assigned to its admin network. victor unified client will receive events from the

secondary NVR via its static IP address. Whether the secondary NVR is in failover mode or

monitor mode, it will send unit-related events to victor unified client using its static IP address.

Adding your secondary NVR in this manner will enable you to monitor its health using the Health

Dashboard feature of victor unified client. For further information on this feature refer to the victor

unified client User Guide.

Backup/Restore

A backup of a secondary NVR can take place while monitoring or while active for a failed NVR.

Backups created will only contain information about the secondary NVR and any information about

any primary NVRs will not be backed up.

Upgrade Considerations

It is recommended that you should upgrade all NVR(s) in the same maintenance window when a

Failover system is present. Should this not be possible there are two methods that can be followed

to carry out the upgrades:

Recommended Method - Upgrading the Secondary First

1 Disable monitoring on all primaries.

2 Upg

rade the secondary.

3 Upg

rade one or more primaries.

4 Re-

enable monitoring on the upgraded primaries. The upgraded primaries now have

failover protection.

5 The primaries that remain at 4.3 will

be without failover protection until they are upgraded.

Upgrade the Secondary Last

1 Disable monitoring on all primaries that you intend to upgrade in this maintenance window

and upgrade them to 4.4.

2 Failover

protection for these primary NVRs will not be available until the secondary is

upgraded, but the primaries that remain on 4.3 will have failover protection until they are

upgraded.

3 Whe

n all primaries have been upgraded, upgrade the secondary and re-enable monitoring

on all primaries.

Note

VideoEdge 4.4 does not support failover functionality for previous versions, for example a

secondary NVR using VideoEdge 4.4 can not assume the role of a primary NVR running

VideoEdge 4.3 and vice versa.

Configure Failover Mode for an NVR

An NVR that is going to be used as a secondary NVR must be installed and configured in the

same way as you would for a primary NVR. You need to configure media folders and storage sets.
