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.

■ 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.

► To enable adaptive recording, please also 

enable time shift caching stream and select a caching 

► 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).

 

for Dynamic Frame Rate Control

I frame   --->   Full frame rate   --->   I frame

► 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.
