The Settings panel of the Video subsystem section

The Video subsystem section is designed for advanced setup of the video subsystem in order to enhance the performance of Intellect.

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	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 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 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 disk space
2	The Frame count field	Enter the value in the field	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	Enter the value in the field / 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	Enter the value in the field / 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 Intellect for a new index to be created	-	-	-
6	The Priority dropdown list	Select the value from the list	Sets the priority of all Intellect video system processes	Names of priority processes	Below normal	Realtime, High, Above normal, Normal, Below normal, Low
7	The Analog video output drop-down list	Select the value from the list	Selects analog output operation mode	Names of available 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	Set the checkbox	Allows access to virtual Video Capture Devices settings (grabber) in Intellect. 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 drop-down 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	Set the 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	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	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 keys 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	Set the 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	Set the checkbox	Switches Intellect from basic to additional driver if there are video artifacts while using basic driver	Boolean type	No	No – Intellect operates with basic driver Yes – Intellect operates with additional driver
13	The Use PureVideo/CUDA hardware acceleration checkbox	Set the checkbox	Enables PureVideo/CUDA support on the Server while decompressing video from IP devices if PureVideo HD card of the 2^nd or 3^rd 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	Set the 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	Enter 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	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	The Camera without video compression table	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 Intellect 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.
