Critical Failover

Strengthen fault tolerance with multi-layered protection

If any part of the CCTV infrastructure fails, the system must first recognize the failure and then switch to a redundant system.
This process can take precious time if done manually, and redundant equipment can be expensive.


Temporary Smart Failover

In Case of an Unstable Network

When the camera's network status is unstable, it starts to save to an internal recording session buffer (NLTSrec, up to 60MB). Therefore, there is no data to break.

Smart Failover

In Case of Network Failure

When the NVR and IP camera are disconnected, the camera’s SD card instantly begins recording and automatically transfers the data to the NVR after recovery, leaving no incident unrecorded.

Storage Redundancy

In Case of Storage Failure

With native RAID 1 support, the NVR saves two identical copies of the data. So if one disk fails, the data is retrieved from the second one.

With native RAID 5 support, if a single drive fails, subsequent reads are calculated from the distributed parity so that no data is lost.

NVR Failover

In Case of Recorder Hardware Failure

If any of the primary NVRs fail, the standby NVR is activated. The primary NVRs and standby NVR continuously monitor one another to quickly respond to problems, reducing the risk of data loss and decreasing failover response times.

Native Dual Power Supply

In Case of Power Supply Failure

When a failed power supply unit (PSU) is replaced, the spare PSU reverts back to redundant operation.
