5.4 Recording Configurations

The “recording configurations” gives users the overall control of how and when a recording

is performed. NVR provide you to select weather to record I Frame only, or to record all

frames delivered by the camera. It can help the NVR to operate with sufficient system

resource by performing recording only when it’s necessary with adjustable recording frame

rate.

Note: In an MPEG video stream, I Frame means a full frame. That is, I Frame does not

need any information from the frame before it or after it to be played back properly. If you

select to record I Frame only, NVR will not save frames other than I Frame.
