Configuring Recording of the Video Stream from Video Cameras to the Archive

To configure recording of the video stream from video cameras to the archive, you must perform the following steps:

1. Left-click the icon in the Linked archive(s) table (1) at the intersection of the row corresponding to the camera from which the video stream should be recorded to an archive and the column corresponding to that archive.
   
   

   Note

   Аrchives are marked with badges of the corresponding colors (see the section Creating archives)

   Note

     Parameters for the video stream that is recorded to disk form the camera are shown in theVideo parameters for recording to archive group (2)

   
   

2. In the Mode list (3), select the desired mode of recording the video stream from the video camera to the archive.

   Recording mode	Description
   No recording	The video stream is not recorded to archive
   Continuous recording	The video stream is recorded to archive continuously
   Scheduled recording	The video stream is recorded to archive according to specific schedules
   Recording on demand	The video stream is recorded to archive when detection units are triggered or when an alarm is manually initiated

3. If scheduled recording has been chosen, in the corresponding drop-down list (3), select the schedule (see the section Configuring schedules) according to which recordings will be written to the archive.

4. If you need to record to archive using scaling, select Yes in the drop-down list (3).

   Attention!

   When a video stream with inter-frame compression (MPEG4 and H.264) is downsampled, only the key frames are preserved. This can cause a large decrease in the frame rate in recorded video (to 2 - 3 fps). If this occurs, we advise you to use such codecs as MJPEG and Motion Wavelet.

5. If you choose recording with scaling, enter the maximum frame rate when recording the video stream from a video camera to the archive in the Max frame rate field (3). If the frame rate of the video stream coming in from a video camera is less than the indicated value, the recording will be made at the original and not the maximum rate.
6. The default archive of a video camera is the archive to which images from a given video camera are recorded during user-initiated alarms. For each video camera one and only one default archive must be set. The first archive to which recording of a video stream from a video camera was configured automatically becomes the default archive.
   If you need to make another archive the default one for this video camera, select Yes in the Default archive list for that other archive (3).

7. In the Pre-alarm recording time field (3), enter the buffering time of the video stream from the camera in seconds. This value should be in the range [0, 120].
   
   

   Note

   Pre-alarm recording is the period of pre-event recording that will be added to the beginning of an alarm event recording

8. Repeat steps 1–6 to configure recording of the video stream from a camera to all desired archives.
   
9. Click the Apply button.

Configuration of recording of the video stream from a camera to archives is complete.
