Video archiving feature implemented in Intellect allows saving video according to the settings and analyze the parts of it that are of interest 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 Video Subsystem tab in the tweaki utility.
The archive is a storage of video recordings created in Intellect. Videos are recorded in a loop. When hard disks run out of the space allocated for storing the archive, the hard disks space is overwritten. The earliest recordings are deleted.
Video archive is stored in the VIDEO folder on the selected system disk. In the VIDEO folder, the subdirectories named in the DD-MM-YY HH (Date, Hour) format are stored. They contain the archive files for the current hour. Video file extension indicates the number of a video camera used to record the archive.
Attention!
Intellect creates and stores video archive in its own format. You can view the archive files without converting in the Video surveillance window, using the converter.exe utility or using the AxxonPlayer utility when you select the required time period.
You can also export the video archive into other formats. For this, you can use the above instruments as well as the AviExport utility. See also Export and print out.
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. You can also record the archive in the MPEG4 format regardless of the codec of the original video signal. For this, create and configure the MPEG4 Encoder object.
There 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.
In order to improve the efficiency of analysis of causes and consequences of alarm events on the protected facilities, Intellect 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 start time of the alarm event recording on the video camera. Pre-alarm event recording allows you to analyze the prehistory of the alarm event.
Attention!
For the cameras without video compression that 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 end time of the alarm event recording on the video camera. Post-alarm event recording allows you to analyze the consequences of the alarm events.
- Hot recording is a video recording segment with higher frame rate. Increased frame rate on the hot recording segment makes event analysis more effective. The hot recording segment always starts from the start time of the alarm event registration. The hot recording is finished at the recording end time (depending on the hot recording settings).
In Intellect, the restrictions are imposed on the use of additional sections when creating a video recording.
Video recording initialization mode | Recording option | ||
pre-alarm | hot recording | post-alarm | |
By Operator command | No | Yes | No |
On alarm event | Yes | Yes | Yes |
On macro/script | Yes | Yes | Yes |
Note
If the MPEG4 recording format is selected, a small fragment of the recording (about 0.5 seconds from the beginning) may be lost.
