Abstract: Transparent backup and archiving of video data for one or more Video Management Systems is provided by capturing such data from at least one network used by the VMS(s) using packet capture by one or more taps and associated Streaming Video Capture and Replay System (SVCRS) and without requiring cooperation from or modification to any VMS. By noting the source and destination of data packets, as well as aspects of the content, such as the data type, format, or protocol used, the nature of the devices sending or receiving the data packets can also be determined. For example, it is possible to determine that a sending device is a camera, and a receiving device is a component of a VMS. Using such information, lists of cameras, VMSs, and clients operating over a network can be created, along with associated information, such as their network addresses. In some cases additional information, such as device capabilities or models, API versions and capabilities, and data storage locations used can also be determined.
