Page History

0 – during the playback, the video archive fragments are read into RAM by one frame

1 – during the playback, the video archive fragments are read into the RAM all at once

0 – the FRAME_SKIPPED event is not generated, core load is reduced

1 – the FRAME_SKIPPED is generated, there is a risk of buffer overflow

The key sets in seconds the delay period between the state changes of frames skipping. Accordingly, the FRAME_SKIPPED\FRAME_SKIPPED_STOP events won’t be generated more often than the period specified in the key.

See CAM Camera

The key sets the minimum number of skipped frames for the period (the period is set in the FileSystem.RecordingStateChangeDelay key), during which the FRAME_SKIPPED event will be generated.

See CAM Camera

The key enables the generation of camera events FILE_REC_ERROR and FILE_REC_OK (see CAM Camera).

0 – FILE_REC_ERROR and FILE_REC_OK events are not generated, the load on the core is reduced

1 – FILE_REC_ERROR and FILE_REC_OK events are generated, there is a risk of buffer overflow

The key enables the feature of counting down the storage period for the Keep no less than parameter from the last archive record timestamp (see also Configuring video camera archive depth).

0 – the archive storage time is counted from the last archive record time stamp

1 – the archive storage time is counted from the current time

The key enables or disables compression of the video recorded on the disk.

0 – compressed video is recorded to the disk according to the settings of each camera

1 – uncompressed video is recorded from all cameras to disk, ignoring the compression settings specified for all cameras

Note. This key is required for debugging. It is not recommended to change the value of this key

The key sets in minutes the time segments of the recorded archive that will be deleted when it is necessary to free up space.

The smaller the value, the smaller segment will be deleted in one deletion iteration, but there will be more such iterations. This will speed up the deletion process and will not overflow the buffer

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

The key specifies the method of clearing the internal data buffer of the OS file system record:

1—forced resetting of the internal buffers of the OS file system record (actual prohibition of record caching)

0—automatic (at the discretion of the system) resetting of the internal buffers of the OS file system record

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

The key specifies the way the archive is recorded to the disk or network storage:

0—each frame is recorded to the disk at once. This value is not recommended to use for network storages

1—at first video is fully recorded to RAM (default video size is 1500 frames, it's specified by the Frame count parameter on the Settings panel of the Video subsystem section of the Tweaki.exe utility, or by the MaxFrames key), temporary files are not created. When the recording ends, it is recorded to the disk by parts, the size of which is set by the FileSystem.WriteBufferSize parameter (4 MB by default). Memory consumption highly increases in this case

-1—at first video is recorded to the temporary file in RAM. The minimum size of the temporary file is limited by the FileSystem.PreAllocateFileSize key value. The maximum size of the temporary file is limited by the FileSystem.WriteBufferMemoryLimit key value. When the size of the temporary file reaches maximum value, it is recorded to the disk. Memory consumption highly increases in this case.

By default, when installing Axxon PSIM, the key is not created

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

The key is used when FileSystem.MemFile=-1 (described above).

Sets the minimum size of a temporary file in RAM in megabytes, i.e., a file of the specified size will be created immediately before writing to it

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

The key enables fast index download. It is used by 64-bit modules only as memory consumption increases when reading and saving.

Regardless of the key value, the fastIndex.index file is created in the VIDEO folder. This file helps to download indexes much faster.

0 – when Axxon PSIM is started, all indexes are downloaded, so no time is wasted for data loading

1 – when Axxon PSIM is started, the specified file is downloaded and the data on detailed index for each hour will be loaded if required

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

The key specifies the size of the video data chunks in megabytes that are recorded to the disk simultaneously. If the size of the frame is less than the specified value, it is "glued" to the next frame.

The key is used when the FileSystem.MemFile key value is 1 or -1

Note. See also WritingQueueSize

100

The key sets number of frames storing in RAM until start of data record to buffer. The key can be used with any codec

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

The key enables a more optimal read of video archive individual frames from the disk. It is created on the Server.

0 – optimization of video archive reading is disabled

1 – optimization of video archive reading is enabled

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

The key specifies the number of channels of simultaneous recording to disk:

0—the maximum possible number of recording channels are used 

1—one recording channel is used

Attention! We don't recommend you change the value of the parameter yourself! Use the assistance of technical support specialists!

x32: (x32)\Video\FileSystem

x64: (x64)\Video\FileSystem

By default, the key isn't created.

It specifies, in milliseconds, the time interval of delay before attempting to access the file subsystem.
