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

500

500 to 10000. It is not recommended to change the default value.

3

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

4

The LinuxHub timeout list

Type-in the value/select from the list

Boolean type

None

No –  Intellect operates with basic driver  

Yes – Intellect operates with additional driver  

6

The Restart recording on archive entering checkbox

Checkbox

Enables restarting record on archive entering. 

Boolean type

None

Yes – 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.


No – recording is not stopped on archive entering

7

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

8

No – the Virtual value is not available for the Video Capture Device objects

12

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.

Checkbox

The Pause button is pressed on archive entering

Boolean type

None

Yes – the Pause button is pressed on archive entering, archive navigation using arrow keys.


No – the Pause button is not pressed on archive entering.

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.

15

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

16

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 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.
