If you enable adaptive recording 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.
The alarm trigger includes: motion detection and DI detection. Please refer to Event settings on page 113.
■ 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 rst.
■ Source: Select a stream for the recording source.
► To enable adaptive recording, please also enable time shift caching stream and select a caching
stream on Media > Video > Stream settings. Please refer to page 73 for detailed instruction.
► To enable recording notication please congure Event settings rst. Please refer to page 113.
Please follow steps 1~2 below to set up the recording:
1. Trigger
Select a trigger source.
■ Schedule: The server will start to record les on the local storage or network attached storage (NAS).
■ Network fail: Since network fail, the server will start to record les onto the local storage (SD card).

► To enable adaptive recording, please make sure
you’ve set up the triggering 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.
