If you enable adaptive recording on a camera, 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 saves 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 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 94.

Pre-event recording and post-event recording

The Network Camera has a buffer that temporarily holds data for a period of time. Therefore, when an event occurs, the camera can restrieve image frames taken several seconds ago. Enter a number to define 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 processed first.

Source: Select a video stream as the recording source.

NOTE:

► To enable recording notification please configure Event settings first . Please refer to page 94.

Please follow the steps below to set up the recording.

1. Trigger

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