Vivotek FD8335H user manual Continuous recording

VIVOTEK

If you enable adaptive recording and enable time-shift cache stream on Camera A, only when an event is triggered on Camera A will the server record the full frame rate streaming data; otherwise, it will only request the I frame data during normal monitoring, thus effectively save lots of bandwidths and storage space.

NOTE:

►To enable adaptive recording, please make sure you’ve set up the trigger source such as Motion Detection, DI Device, or Manual Trigger.

►When there is no alarm trigger:

-JPEG mode: record 1 frame per second.

-H.264 mode: record I frame only.

-MPEG-4 mode: record the I frame only.

►When the I frame period is >1s on Video settings page, firmware will force decrease the I frame period to 1s when adaptive recording is enabled.

The alarm trigger includes: motion detection and DI detection. Please refer to Event Settings on page 92.

■ Pre-event recording and post-event recording

The Network Camera has a buffer area; it temporarily holds data up to a certain limit. Enter a number to decide the duration of recording before and after a trigger is activated.

■Priority: Select the relative importance of this recording (High, Normal, or Low). Recording with a higher priority setting will be executed first.

■Source: Select a stream for the recording source.
