Title:
PRE-EVENT VIDEO RECORDING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/124800
Kind Code:
A1
Abstract:
Embodiments of the present invention disclose a pre-event video recording method and device. Firstly, upon acquisition of a recorded video of a first type being an event type, a cloud server performs a pre-event recording-related task. For applicability in both a fixed-time recording scenario and an unfixed-time recording scenario, the method first determines whether pre-event recording can be performed locally when performing the pre-event recording-related task. If the pre-event recording cannot be performed locally, the pre-event recording is achieved by employing surveillance equipment. In the fixed-time recording scenario, the cloud server stores an acquired recorded video of a fixed-time type and an acquired recorded video of the event type separately on the cloud, and the volumes of storage spaces can be configured according to requirements, such that pre-event recording with a longer duration can be achieved in the fixed-time recording scenario. In the unfixed-time recording scenario, a prior recorded video is stored in a non-volatile storage space having a large and expandable volume in a storage space for prior recorded videos, thereby increasing the duration of prior recorded videos, and ultimately realizing pre-event recording with a longer duration. The present solution achieves the purpose of enabling longer pre-event video recordings upon completion of video recording of an unexpected event.
