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 87.

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 Media > Video > Stream settings. Please refer to page 79 for detailed instruction.

To enable recording notification please configure Event settings first. Please refer to page 87.

Please follow steps 1~2 below to set up the recording:

1. Trigger

Select a trigger source.

Schedule: The server will start to record files on the local storage or network attached storage (NAS).

Network fail: Since network fail, the server will start to record files onto the local storage (SD card).
