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:
“An avant-garde man is like an enemy inside a city he is bent on destroying, against which he rebels; for like any system of government, an established form of expression is also a form of oppression. The avant-garde man is the opponent of an existing system.”
—Eugène Ionesco (b. 1912)
“How utterly futile debauchery seems once it has been accomplished, and what ashes of disgust it leaves in the soul! The pity of it is that the soul outlives the body, or in other words that impression judges sensation and that one thinks about and finds fault with the pleasure one has taken.”
—Edmond De Goncourt (1822–1896)
“... the structure of our public morality crashed to earth. Above its grave a tombstone read, “Be tolerant—even of evil.” Logically the next step would be to say to our commonwealth’s criminals, “I disagree that it’s all right to rob and murder, but naturally I respect your opinion.” Tolerance is only complacence when it makes no distinction between right and wrong.”
—Sarah Patton Boyle, U.S. civil rights activist and author. The Desegregated Heart, part 2, ch. 2 (1962)
