The Video subsystem section is designed for advanced setup of the video subsystem in order to enhance the performance of the Axxon PSIM system.
The settings panel for the Video subsystem section is shown in the figure.
The parameters of the settings panel are described in the table.
No | Parameter name | Field type | Description | Representation | Default value | Value range |
1 | The Ring field | Type-in the value | Sets free disk space; when the limit is reached the earliest recordings will be deleted on loop (see General information on video archiving). If 2 or more disks are in use for video archiving, archiving on current disk is performed till there is FreeMbCritical of free disk space (1000 Mb by default, see the info on the key in Registry keys reference guide). Free space set by the Ring parameter is used for recording temporary files. This means that when the limit set by the Ring parameter is reached, the maximum size of the temporary file is FreeMbCritical. Video can contain less frames than set by the Frame count parameter. | MB | 1000 | Depends on the disk space |
2 | The Frame count field | Type-in the value | Sets the maximum number of frames in one recording file. | frame | 1500 | 1500 to 10000. It is not recommended to change the default value. |
3 | The Recording time list | Type-in the value/select from the list | Sets the length of the file in seconds, restricting fragment’s size not by number of frames but by time of its recording. | Time in sec | 0 | Unlimited |
4 | The Record restart when entering the archive checkbox | Type-in the value/select from the list | Enables restarting record on archive entering. | Integer | No | 0 – patch that has been recorded on archive entering is stopped and a new one starts. As a result the user who enters the archive sees a freeze frame corresponding to that on exiting. >0 – the recording is restarted when entering the archive, while positioning in the archive is carried out with a shift back to the specified value in seconds. -1 – recording is not stopped on archive entering |
5 | The Rebuild index button | Click the button | Deletes the database index file. After deleting the index, restart the Axxon PSIM system for a new index to be created. | - | - | - |
6 | The Priority dropdown list | Select the value from the list | Sets the priority of all Axxon PSIM video system processes | Names of priority processes | Below normal | Realtime, High, Above normal, Normal, Below normal, Low. |
7 | The Analog video output dropdown list | Select the value from the list | Selects analog output operation mode. | Names of availiable modes | All | All - video signals from all the analog outputs are displayed on one screen One – video signal from one analog output is displayed on one screen |
8 | The Use virtual grabber checkbox | Checkbox | Allows access to virtual Video Capture Devices settings (grabber) in Axxon PSIM Note. Desktop Experience Feature is to be enabled when using a virtual video capture device on server OS and avi files. | Boolean type | No | Yes – the Virtual value is available from the Type dropdown list on the settings panel of the Video Capture Device objects No – the Virtual value is not available for the Video Capture Device objects |
9 | The Hide mask checkbox | Checkbox | Prohibits displaying video hidden with the motion detector mask. Video area marked with motion detector mask will be grey-filled. This feature supports only uncompressed video from FS or FX video capture cards. | Boolean type | No | No — video hidden with the mask is displayed Yes – video hidden with the mask video is not displayed |
| 10 | The Automatic font size selection for export checkbox | Checkbox | Enables the relative font size for captions (camera No. and time) when exporting a frame or fragments of the video archive. | Boolean type | No | No – when exporting a frame, regardless of the video resolution, the caption size remains constant as set by the SubtitlesFontSize registry key, see the Registry Key Reference Guide. Yes – when exporting a frame, the caption size is scaled depending on the video resolution. |
| 11 | The Gradual increment of camera tile checkbox | Checkbox | Enables a gradual increase of the Video Surveillance window on the custom layout by double-clicking the left mouse button. All Video surveillance windows on the layout should be the same size to ensure proper operation of the key. | Boolean type | No | No – the Video surveillance window is expanded to the entire Video surveillance monitor by double-clicking the left mouse button. Yes – by double-clicking the left mouse button, the Video Surveillance Window is enlarged gradually: the first double-click enlarges it 2 times of the initial size, the second double click enlarges 3 times of the initial size, etc. The Video Surveillance Windows adjacent to it are hidden on the layout. |
12 | The Swap frame fields checkbox | Checkbox | Switches Axxon PSIM from basic to additional driver if there are video artifacts while using basic driver | Boolean type | No | No – Axxon PSIM operates with basic driver Yes – Axxon PSIM operates with additional driver |
13 | The Use PureVideo/CUDA hardware acceleration checkbox | Checkbox | Enables PureVideo/CUDA support on the Server while decompressing video from IP devices if PureVideo HD card of the 2nd or 3rd generation (NVIDIA VP2 and VP3) is installed. Used to reduce Server load due to resources of graphics processor | Boolean type | Yes | No –PureVideo/CUDA is not in use Yes –PureVideo/CUDA is in use |
| 14 | The Pause playback at archive entry checkbox | Checkbox | The Pause button is pressed on archive entering | Boolean type | No | Yes – the Pause button is pressed on archive entering, archive navigation using arrow keys. No – the Pause button is not pressed on archive entering. |
15 | The Step of digital zoom scale field | Setting the value in the field / select the value from the list | Specifies the fractional step of video image zooming | Real numbers with the fixed point | 2,00 | Maximum value depends on the maximum scale of digital zoom (see. №17). Minimum value is 1,00. |
16 | The Maximum scale of digital zoom field | Setting the value in the field / select the value from the list | Specifies the maximum value of digital zoom of video image | Numbers | 16 | 1-16 |
17 | The Camera without video compression table | Type-in the value in the field | Specifies the numbers of cameras connected to the video capture cards with compression. There is no compression for these cameras, i.e. the compressor settings in Axxon PSIM are ignored. | Camera’s serial number | - | Depends on the number of cameras registered in the system |
Note.
Setting the non-zero value to the Recording time parameter does not exclude the Frame count parameter. If the values for both parameters are set, then the file recording will be performed in accordance with the value which comes first. For instance, if the value of Recording time is equal to 10 seconds and Frame count is equal to 500 frames (by default) and in ten seconds the fragment consists of 80 frames, then 80-frame file is recorded.
