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.
In Case of an Unstable Network...
Temporary Smart Failover
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.
In Case of Network Failure...
Smart Failover
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.
In Case of Storage Failure...
Storage Redundancy
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.
In Case of Recorder Hardware Failure...
NVR Failover
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.
In Case of Power Supply Failure...
Native Dual Power Supply
When a failed power supply unit (PSU) is replaced, the spare PSU reverts back to redundant operation.
