Abstract
A network video recorder having a multi-stream recording function which is robust to event stream delay is provided. An event stream is recorded by adjusting a time-lapse recording end time and an event recording time to prevent omission of a video, caused by transmission delay of a high-quality event stream during the recording of the event stream.
