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.

NOTE:

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.

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 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 73 for detailed instruction.

To enable recording notification please configure Event settings first. 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 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).
