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

“In full view of his television audience, he preached a new religion—or a new form of Christianity—based on faith in financial miracles and in a Heaven here on earth with a water slide and luxury hotels. It was a religion of celebrity and showmanship and fun, which made a mockery of all puritanical standards and all canons of good taste. Its standard was excess, and its doctrines were tolerance and freedom from accountability.”
—New Yorker (April 23, 1990)
