This document discusses using cloud computing for CCTV video surveillance. Some key points: - Cloud infrastructure reduces the need for in-house IT resources and provides scalability, reliability and cost savings compared to on-premise systems. - However, storing and transferring raw CCTV video data to the cloud is not viable due to the huge size of video files and bandwidth limitations. - Instead, "smart cameras" can analyze video locally to extract metadata and detect meaningful events, only transferring thumbnail images or short clips to reduce transmitted data. - This approach filters data similar to how particle physics experiments filter collision data from the LHC to identify rare events like the Higgs boson.
