Surveon Failover Benefits
Cost-efficiencyNo spare NVR needed. Only add on licenses for failover purpose when
Flexible ArchitectureOne or more NVRs can take over other protected NVRs under various system
Zero Video LossAllow recording to be continued by collaborative NVRs within the system.
Seamless Live View & PlaybackWith external storage structure, the live view and playback for the failed NVR can still be
processed by Failover NVR.
Solution Architecture All NVRs can record normally without having to spare one NVR simply for failover purpose. Support mutual back-up among NVRs.
1 Failover NVR to multiple Protected NVRs Multiple Failover NVRs to Multiple Protected NVRs
Support different system structures.
Solution Mechanism Both NVR1 & NVR2 perform recording under normal situation while NVR1 is with Failover
function and NVR2 is the protected NVR.
When NVR2 is detected as no responding or working for certain time, the system will be
determined as failed.
NVR1 will start importing NVR2 configuration and take over to record for NVR2 automatically.
When NVR2 recovers and begin to record for 5 minutes, NVR1 will stop recording for NVR2
NVR2 under protection
NVR1 with Failover function
Internal Storage Structure When using internal storage, NVR2s video will be recorded to NVR1 internal storage when it
External Storage Structure When using external storage, NVR2s video will be saved to the same location where it is
recorded, even the recording is taken over by NVR1.
Under this structure, the live view and playback for NVR2 can still be done seamlessly.
Normal Condition Failover Enable
License Capability NVR can only perform failover with failover licenses.
Failover licenses only support the same amount of cameras.
Only NVR FW version 4.0 or above support failover function.
