Video archiving feature implemented in Axxon PSIM allows saving the footage video according to the settings and analyse the fragments analyze the parts of it that are of interest for to the user.
The archive is saved on the Server storage device. Video is stored in the archive as one or more indexed files. To limit the size of the files, use the the Video Subsystem tab in the Tweaki.exe tweaki utility.
The archive represents the storage for the is a storage of video recordings that are made created in Axxon PSIM software. Loop recording is used here. When the hardwares . Videos are recorded in a loop. When hard disks run out of the space allocated to for storing the archive storage, the rewriting of footprint starts. It is made on the principle of overwriting the earliest recordingshard disks space is overwritten. The earliest recordings are deleted.
Video archive is stored in the VIDEO folder on the selected system disk. Child directories with titles in «DDIn the VIDEO folder, the subdirectories named in the DD-MM-YY HH» HH (Date, Hour) format are stored in the VIDEO folder. Archive . They contain the archive files for the current hour are here. Video file extension indicates the number of a video camera that is used for video used to record the archive.

Axxon PSIM software creates and stores video archive in its own format. One You can view the archive files without converting with in the Video surveillance window, using the converter.exe utility or using the AxxonPlayer utility (if when you chose select the required time period). Video archive You can also be exported to export the video archive into other formats. For thatthis, you can use the above instruments as well as the AviExport utility can be used. See also 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 signal — see Compressing and decompressing a video signal. You can also record the archive in the MPEG4 format regardless of the codec of the original video signal: for . For this, create and configure the MPEG4 Encoder object. |
Video
signal recording may be initialized by one of three methodsThere are three ways to start video recording:
- Forced recording by the Operator command;
- Automatic recording upon alarm registration;
- Automatic recording upon a macro/script/program execution.
To make the In order to improve the efficiency of analysis of the causes and effects consequences of an alarm event more effective, Axxon PSIM software performs expanded schemes of alarm events on the protected facilities, Axxon PSIM implements the expanded schemes for creating a video recording file. An example of a video recording expanded scheme is given in the figure below.
...
The scheme contains the following segments:
Pre-alarm event is recorded before the recording start time of the alarm event recording on the video camera alarm. Pre-alarm event recording option facilitates the analysis of event causesallows you to analyze the prehistory of the alarm event.
Note title Attention! For the cameras without video compression that have been were added to the corresponding list in the Video subsystem section in the tweaki.exe utility (see The Settings panel of the Video subsystem section), video is not recorded in Pre-alarm record mode.
- Post-alarm event is recorded after the recording end time of the alarm event recording on the video camera alarm. Post-alarm event recording option facilitates the analysis of event consequencesallows you to analyze the consequences of the alarm events.
- Hot recording – is a video recording segment with higher frame rate. Increasing Increased frame rate on the Hot hot recording segment makes event analysis more effective. The Hot The hot recording segment always starts from the recording start time on of the alarm event registration. The Hot hot recording segment is finished at the recording end time (depending on the Hot hot recording settings and event duration).
Further In Axxon PSIM, the restrictions are imposed on the use of additional sections when creating a video recording segments is restricted by Axxon PSIM software. The list of restrictions is given in the table.
