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
Famous quotes containing the words system, fault and/or tolerance:
“In a universe that is all gradations of matter, from gross to fine to finer, so that we end up with everything we are composed of in a lattice, a grid, a mesh, a mist, where particles or movements so small we cannot observe them are held in a strict and accurate web, that is nevertheless nonexistent to the eyes we use for ordinary living—in this system of fine and finer, where then is the substance of a thought?”
—Doris Lessing (b. 1919)
“The wisest conservatism is that of the Hindoos. “Immemorial custom is transcendental law,” says Menu. That is, it was the custom of the gods before men used it. The fault of our New England custom is that it is memorial. What is morality but immemorial custom? Conscience is the chief of conservatives.”
—Henry David Thoreau (1817–1862)
“Persecution was at least a sign of personal interest. Tolerance is composed of nine parts of apathy to one of brotherly love.”
—Frank Moore Colby (1865–1925)
