Method and device for additionally recording video

Abstract

Embodiments of the invention disclose a method and device for additionally recording a video. Firstly, a cloud end server performs an additional recording task after obtaining a first-type record belonging to an event type; however, in order to simultaneously fit to a timing recording scene and a scene without timing recording, when performing the additional recording task, the cloud end server firstly judges whether the local can additionally record the video, and if the local cannot additionally record the video, the cloud end server implements the additional recording based on a monitoring device. Furthermore, in the timing recording scene, the cloud end server independently stores the obtained timing type records and event type records in a cloud end, the capacity of a storage space can be set according to requirements, and additional recording with longer time can be performed based on the timing record; and in the scene without timing recording, a history record is stored in a extensible nonvolatile storage space with a relatively larger monitored record storage space, so that the time of the history record is relatively longer. Finally, additional recording with the longer time can be implemented. Through the technical scheme, a purpose of additionally recording a record with the longer time is implemented after an event record aiming at an emergency is completed.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video supplementary recording method and device. Background technique [0002] In the video surveillance system, when it is necessary to record an emergency event, the monitoring equipment on the user side will upload the alarm signal to the monitoring platform, and the monitoring platform will generate an event recording pulse for the monitoring equipment and send it to the monitoring platform after receiving the alarm signal. Correspondingly, after the cloud server receives the event recording pulse sent by the monitoring device, it will take the stream from the monitoring device in real time (that is, obtain the video data collected by the monitoring device in real time), and take the video obtained by streaming It is stored by event type, and in order to ensure the integrity of the video recording about the emergency, there is a demand for supplementary recording of the vide...

Problems solved by technology

Although this method can realize the pre-recording function, as the demand for pre-recording time increases, the memory consumption will gradually increase. Due to the influence of the memory of the cloud server, the re-recording time is shorter
