Binding a camera to an archive determines the archive to which a video stream will be recorded and how.
You can bind a single camera to an archive or bind a group of cameras by using the same settings.
To bind a camera to an archive:
In the Depth, days field, set the retention time value for the given camera (in days).
If the history value is set at 0, all recorded video is available for playback. |
Further, if you are increasing the Archive retention time (0 — stands for unlimited time), this setting is applied for new records only. Earlier records falling outside the initial retention time become inaccessible. |
When setting a retention time parameter for a particular camera archive, please note that global retention time limits have higher priority (see Configuring access restrictions to older footage). If your entire archive is set to, say, 10 days, and the camera retention time is set to 20 days, camera footage will be actually retained for 10 days only. |
In the Pre-alarm recording time field (4), enter the buffering time of the video stream from the camera in seconds. This value should be in the range [0, 30].
Pre-alarm recording is the period of pre-event recording that will be added to the beginning of an alarm event recording |
If a macro starts recording, the pre-alarm recording time may be longer, according to your settings (see Record to archive). |
To reduce the frame rate of the video that is written to the archive, select the maximum frame rate from the Maximum fps list or manually enter a value in the field. Otherwise, set this value to No (5). 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.
If you prune / downsample MPEG4 or H.264 video (interframe compression codes), only the keyframes are retained. This leads to a significant drop of fps (down to 2-3). In such cases, we recommended that you use MJPEG. |
Select a stream for archive recording (6).
This setting is relevant for cameras that support multistreaming. |
Binding of the camera to the archive is now complete.
To bind multiple cameras:
The camera is now bound to the archive.
