IDIS 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.
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.
