The Settings panel of the Video subsystem section

The Video subsystem section is used for advanced configuration of the video subsystem in order to enhance the performance of Axxon PSIM.

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	Method of setting the parameter value	Parameter description	Representation	Default value	Value range
1	Ring	Enter the value in the field	Sets free disk space; when the limit is reached, the earliest recordings will be deleted on loop (see General information on video archiving). If two or more disks are used 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 Ring (registry key FreeMb). Video can contain less frames than set by the Frame count parameter. Note. Old recordings may get deleted before the remaining disk space reaches the specified value if the disk space is less than 15000	MB	5000	Depends on the hard disk space
2	Frame count	Enter the value in the field	Sets the maximum number of frames in one recording file	Frame	1500	1500 to 10000. We don't recommend changing the default value
3	Recording time	Enter the value in the field/select the value 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 seconds	0	Unlimited
4	Restart recording on entering the archive	Enter the value in the field/select the value from the list	Enables the restart of recording on entering the archive	Integer	No	0—video fragment that was being recorded at the moment of entering the archive is forcibly stopped, and a new one starts. As a result, the user who enters the archive sees a freeze frame corresponding to the moment of entry >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 at the moment of entering the archive
5	Rebuild index	Click the button	Deletes the file that stores indexes. After deleting the file, click the Rebuild index button to restart Axxon PSIM and create a new file with updated indexes	-	-	-
6	Priority	Select the value from the drop-down list	Sets the execution priority of all Axxon PSIM processes	Names of priority processes	Below normal	Realtime, High, Above normal, Normal, Below normal, Low
7	Analog video output	Select the value from the drop-down list	Selects the operation mode of the analog output	Names of available modes	All	All—video signal from a camera is displayed on a separate analog monitor One—video signals from cameras that are connected to different video capture devices, are displayed on a separate analog monitor
8	Use virtual grabber	Set the checkbox	Allows access to virtual Video capture devices settings in Axxon PSIM. Note. *Desktop Experience Feature* must be enabled when using a virtual video capture device on server OS and avi files	Boolean type	Clear	Set—the Virtual and Virtual bench values are available from the Type drop-down list on the settings panel of the Video capture device objects Clear—the Virtual and Virtual bench values aren't available for the Video capture device objects
9	Hide mask	Set the checkbox	Disables displaying the video hidden by the motion detection mask. Video area marked by motion detection mask will be hidden by a grey fill. This feature works only on uncompressed video from FS or FX local video capture cards	Boolean type	Clear	Clear—video hidden by the mask is displayed Set—video hidden by the mask video isn't displayed
10	Automatic font size selection for export	Set the checkbox	Enables the relative font size for captions (camera No. and time) when exporting a frame or fragments of the video archive	Boolean type	Clear	Clear—when exporting a frame, regardless of the video resolution, the caption size remains constant as set by the SubtitlesFontSize registry key, see the Registry keys reference guide Set—when exporting a frame, the caption size is scaled depending on the video resolution
11	Gradual increment of camera tile	Set the checkbox	Enables a gradual increase of the Surveillance window on the custom layout by double-clicking the left mouse button. All Surveillance windows on the layout must be of the same size to ensure proper operation of the key	Boolean type	Clear	Clear—Surveillance window is expanded to the entire Video surveillance monitor by double-clicking the left mouse button Set—by double-clicking the left mouse button, the Surveillance window is expanded gradually: the first double-click expands it two times of the initial size, the second double-click expands it three times of the initial size, and so on. The Surveillance windows adjacent to it are hidden on the layout
12	Swap frame fields	Set the checkbox	Switches Axxon PSIM from basic to additional driver if there are video artifacts when using the basic driver	Boolean type	Clear	Clear—Axxon PSIM operates with basic driver Set—Axxon PSIM operates with additional driver
13	Use PureVideo/CUDA hardware acceleration	Set the checkbox	Enables PureVideo/CUDA support on the Server when decompressing video from IP devices if PureVideo HD card of the second or third generation (NVIDIA VP2 and VP3) is installed. Used to reduce CPU load due to resources of graphics processor	Boolean type	Set	Clear—PureVideo/CUDA isn't used Set—PureVideo/CUDA is used
14	Pause playback at archive entry	Set the checkbox	The Pause button is clicked when entering the archive	Boolean type	Clear	Set—the Pause button is clicked when entering the archive, you can navigate through the archive using arrow keys Clear—the Pause button isn't clicked when entering the archive
15	Step of digital zoom scale	Enter the value in the field/select the value from the list	Specifies the fractional step of video image zooming	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	Maximum ratio of digital zoom	Enter 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	Cameras without video compression	Enter 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 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 disable 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 10 seconds the fragment consists of 80 frames, then 80-frame file will be recorded.
