Page History
Video and audio archives store copies of video and audio recordings created by the Axxon PSIM software.
All archives are subdivided divided into the following types:
- Main archive—the video server archive;.
- Backup archive—an archive developed with the assistance of the functional module archive—archive created using the Backup archive module.
- External archive—an archive Edge storage—archive stored in the embedded storage of the external IP device (NVR video recorder). There is no recording Recording to this archive is not performed.
- Video gate archive—an archive recorded with the Video gate functional module. The video gateway Videogate archive—archive created using the Videogate module. Videogate is used to reduce the load on the network when sizeable data flows are transmitted from the video servers to the remote workstations.
If the video gateway videogate is on, data from the video servers is not transmitted directly to the remote workstations , but through the video gatewayvideogate, which in turn distributes received data among the workstations. The video gateway cannot videogate can function as a Backup backup archive, unless it is the case where recording should must be resumed; if the communication line fails, video recording is resumed from the beginning, instead of from the cut-off point.
The table compares the characteristics of archives and the corresponding functional modules.
