Surveillance System Fault Tolerance
It is more fault-tolerant because if one edge recorder fails then only those cameras connected to that unit stop recording. In a centralized approach, all cameras would cease to be recorded.
Additionally, if the network, or communications path, fails for a period of time video from all cameras on the down network is lost forever. On the edge-based storage solution video is still being recording while the network is down, so if an event of interest occurs while the network is down the video recording may be recovered by going out to the edge device, or after the network has been restored.Read more about this topic: Recording At The Edge
