If No is selected, the video stream will be recorded to the archive only when an operator manually initiates an alarm or an automatic rule is initiated.
If Always is selected, video will be recorded to the archive non-stop.
If a time schedule is selected (see Configuring schedules), video will be recorded non-stop to the archive during the selected time period. Recording to the archive can also be initiated by the operator or an automatic rule. 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].
Info title Note Pre-alarm recording is the period of pre-event recording that will be added to the beginning of an alarm event recording
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 (4). 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.
Note title Attention! 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 or Motion Wavelet Flex Stream codes.
