The archive is saved on the Server storage. Video is stored in the archive as one or more indexed files. To limit the size of the files, use the Video Subsystem tab in the Tweaki.exe utility.
The archive represents the storage for the video recordings that are made in Axxon PSIM™ PSIM software. Loop recording is used here. When the hardwares run out of the space allocated to archive storage, the rewriting of footprint starts. It is made on the principle of overwriting the earliest recordings.
...
Video archive is stored in the VIDEO folder on the selected system disk. Child directories with titles in «DD-MM-YY HH» (Date, Hour) format are stored in the VIDEO folder. Archive files for the current hour are here. Video file extension indicates the number of video camera that is used for video archive.

Axxon PSIM software creates and stores video archive in its own format. One can view the archive files without converting with the Video surveillance window, using the converter.exe utility or using the AxxonPlayer utility (if you chose the required period). Video archive can also be exported to other formats. For that, the above instruments as well as the AviExport utility can be used. See also Operator's Guide , the Export and print out section. The codec in which the archive is recorded is by default determined by the codec of the original video signal – see Video signal compression and decompression. It is also possible to record an archive in MPEG4 format regardless of the codec of the original video signal: for this, create and configure the MPEG4 Encoder object. |

To make the analysis of the causes and effects of an alarm event more effective, Axxon PSIM™ PSIM software performs expanded schemes of video recording file. An example of a video recording expanded scheme is given in the figure below.

Further use of video recording segments is restricted by Axxon PSIM™ PSIM software. The list of restrictions is given in the table.
