Abstract
Security information such as fixed or dynamically received camera location information, laser signature information, timestamp information, and network information, may be used to secure the transport and storage of surveillance video. Where the surveillance video is to be transported on a communication network, the round trip time from a video data storage server to the surveillance camera and back to the video data storage server may be monitored and periodically added to the secured video data. By checking to see whether the round trip time has changed, it may be possible to determine whether the video has been tampered with. The secured video data may also be transported over two or more paths on the network to two or more video data storage servers so that redundant copies may be stored at different primary locations. By comparing copies of the data, alteration of one of the copies may be detected.
