NVR Failover

213

• The secondary NVR will send the following email notifications stating; “Activating Failover Mode

for NVR at primary-IP-address” and “NVR services are being shut down.”

• The primary NVR will send the following email notifications st

ating; “Primary NVR transitioning to

standby state” and “NVR services are being shut down.”

Virtual IP Addresses

When adding a primary NVR for monitoring you will be required to enter a virtual IP address for

that NVR. The virtual IP address allows you to seamlessly search and retrieve video from the

secondary NVR which was recorded during the failover period.

The virtual IP address must belong to the manag

ement interface (client LAN) subnet on the

secondary NVR. The NVR and victor unified client communicate over the management interface

(client LAN). If the virtual IP address does not belong to one of the secondary NVR’s subnets, the

settings will not be applied and an error message will display. If using DHCP you must allocate a

range of addresses for use as virtual IP addresses to ensure conflicts do not occur.

Recorded video on the secondary NVR is associa

ted with the virtual IP address of the primary

NVR. Should the secondary NVR be required to switch to failover mode for multiple NVRs during

its operation the recorded video associated with each primary NVR can be retrieved.

Note

When the secondary NVR’s available storage is depleted, data culling will occur. To manage

storage you can configure the maximum retention for each slot that may be populated by a

recording device in the event of Failover.

Using an NVR in Failover Mode

When viewing Live Video on victor unified client from a primary NVR and the primary NVR fails,

the secondary NVR will automatically take over the connection to view live video. The victor unified

client will timeout and retry playing live video from the virtual IP address. victor unified client will

automatically reconnect to the camera’s live video streams to view live video.

Note

If a search and retrieve is in progress when a primary NVR fails, the search will not be completed

successfully.

Events

During Failover mode events will be sent from the secondary NVR on behalf of the primary NVR,

these events include video loss, motion detection events, video intelligence events, dry contact

events and so on. These events will be displayed within victor unified client as if they have been

sent by the primary NVR. You can use victor client to view the video that is associated with these

events.

When Failover mode is active the secondary NVR assu

mes the virtual IP address of the failed

primary NVR.

The victor unified client will use the virtual IP address

to receive events from the secondary NVR.

When the primary NVR is active and generates an event, it sends the event to victor unified client.

When Failover mode is active, media-related events will be sent by the secondary NVR providing

a seamless appearance in the victor unified client. Events will appear as if they have been

received from the primary NVR at all times, even when failover mode is active.
