Toshiba IK-WD04A user manual 100

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 streaming data in full frame rate; otherwise, it will only request the I frame data during normal monitoring, thus effectively save lots of bandwidths and storage.

NOTE

●To enable adaptive recording, please make sure you’ve set up the trigger sources 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 the I frame only.

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

●When the Intra frame period has been set to larger than >1s on Video settings page, the Intra frame period will be forced into 1s when the adaptive recording is activated.

The alarm trigger includes: motion detection and DI detection. Please refer to Event settings on page 82.

■ 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.

NOTE

●To enable adaptive recording, please also enable time shift caching stream and select a caching stream on Video > Stream settings. Please refer to page 75 for detailed instruction.
