Method and device for storing warning image

Abstract

The embodiments of the present application provide an alarm image recording method and apparatus, the method includes: capturing a picture according to a preset frequency, and caching the picture captured each time to a buffer of the video capture device; extracting, after a preset time period since when occurrence of an event meeting an alarm condition is detected, at least two pictures from the buffer according to a time point at which the event occurs; determining the at least two pictures as alarm images and saving to the video capture device or a cloud storage server. In the present application, since the alarm image including at least two pictures may provide more abundant information than an alarm image including a single picture, the completeness of presenting the event by the alarm image can be improved. Compared with the alarm image including a video, the amount of data is reduced by at least an order of magnitude, thus reducing data amount of the alarm image. Therefore, the alarm image including at least two pictures can improves the completeness of presenting the event while reducing the data amount of the alarm image, and achieves a better recording effect.
