To store video on your video units, and periodically transfer those recordings to Security Center, you must enable edge recording on the units and configure the cameras to transfer video to their main Archiver.
Before you begin
What you should know
You can continue to record video on the Archiver, even if the camera is configured for archive transfer. Cameras can only be added to one transfer group for retrieving video recordings from units.
Archive transfer from units to Archivers is helpful in the following scenarios:
- For remote sites connected to a central site with limited bandwidth: Typically, a server is deployed at the remote site to host the recording. However, with archive transfer you can retrieve the video directly from the cameras on demand without requiring a server.
- For city-wide surveillance using edge recording cameras: Cameras are always recording. Recordings are only retrieved on demand for investigation purposes, or outside of peak hours.
- If there is a network failure, the portions of video that are missing from the Archiver recordings can be retrieved from the video unit.
