Abstract
One embodiment of the present invention provides a cloud-based video monitoring system comprising a camera and a network video recorder (NVR). During operation, the camera stores in a buffer last predetermined temporal segment of a video. The camera also stores a first video file in a local storage corresponding to an event detected by the camera. This first video file is non-overlapping with a second video file corresponding to the event and this second video file is stored in the NVR. The camera generates a third video file by pre-pending last predetermined temporal segment of a video prior to the event to the first video file and sends the third video file to the NVR.
