that of ASF, so the file size is bigger. The database file size is also up to 500MB; so no matter how large
value you set in “Media-file Maximum Size”, once the database size reach 500MB, video data will be split
into a new database file.
Decode Audio/Video Stream
Select whether to decode the video and audio stream from compressed capture source. This setting is
important for large-scale deployment of IP solution. For example, if you use a server to connect 64 IP
cameras and each camera streams high resolution compressed video/audio (may be in MJPEG or other
compression format) to the server. In this case you may want to disable decoding because you do not
want to exhaust your server by decoding all 64 channels audio/video simultaneously. The disadvantage
for this is that you no longer can use filers or motion/event detectors in the channel which decode-option
is disabled. Instead you can setup multiple client PCs to connect to some selected channels of the server
and do whatever you want as usual.
Stream break tolerance in media file
Enter a value when the media file is to be closed. This feature is generally used with “compress on event”
in Compression module. For example, if you configure this value to 5000ms and there has been no event
for 5000 ms, the current media-file will be saved and closed. The next recording will be on a new file.
Participate in Storage Recycle
Check this box to permit deleting the recorded video files of this channel under the “Storage Recycled”, a
feature that deletes old media-file when storage space is running low..
Media-file maximum size
Enter the maximum size of a media-file. A media-file will be closed when it reaches this size and a new
one will be opened to continue recording.
Attach audio time adjustment
Use this menu to adjust the sample time of the attached audio source. Typically this value is used for tun-
ing synchronization of video and attached audio. Please note that the adjustment will NOT reflect on real-
time preview, but will affect local video storage and network video streaming. Please also note that this
value affect only “attach audio source”. Audio embedded with video source (such as a local video file) will
not be affected.
Media source buffering
Enter the buffer size for video/audio source before the media is passed to through the pipeline. This set-
ting is typically used with network video/audio source, such as “Connect to other iN7000”. If the preview
video of a channel is lagging, you may try to tune this value (otherwise 1000 ms is recommended).
