In the embodiment, the alarm with a video plan is considered, the alarm video is not stored independently, but when the alarm is triggered, a piece of data is added into a database and marked as alarm data, and the video before and after the alarm and the video within the alarm time are used as the alarm video together; when the alarm of the video plan is not configured, a pre-recorded file is set and used for recording videos within a period of time in a circulating mode, when the alarm is triggered, the videos within the alarm time are recorded, after the alarm is finished, the videos within the period of time are recorded continuously, the videos in the pre-recorded file, the videos within the alarm time and the videos within the period of time after the alarm are stored as alarm videos together, and meanwhile, a piece of data is added into a database and marked as alarm data.
As shown in fig. 4, the alarm video and the general video are stored in the same file, and the alarm video does not need to be stored separately, but the database includes two pieces of data, one piece of data is the alarm data, and the other piece of data is the data of the general video. As shown in fig. 4, (1) is a piece of data of the alarm video recorded in the database, and the start time and the end time of the alarm are recorded, wherein the start time and the end time of the alarm are related to the linkage video configured in the alarm plan, when the alarm video is configured, videos before and after the linkage alarm incident are set for a period of time, for example, videos before and after the linkage alarm incident are set for 60s, the start time of the alarm video is the time of receiving the alarm signal minus 60s, the end time of the alarm video is the time of ending the alarm plus 60s, and meanwhile, the flag mark in the database is 1, that is, the piece of data is stored as the alarm video data.
The specific process of this embodiment is shown in fig. 5, and mainly includes the following steps:
s501, configuring a video recording plan for the front-end equipment on the service platform, wherein the video recording plan comprises a channel of the equipment, a life cycle of storage and the like;
s502, configuring an alarm plan for the front-end equipment on the service platform, wherein the alarm plan comprises an alarm source, an alarm type, an associated user, an alarm linkage type and a linkage video (a video in a certain period of time before and after the alarm);
s503, storing the video of the channel to which the video recording plan is configured in S501;
s504: adding a piece of data in the database to query the video files stored in S503, and continuously updating the data in the database according to the change of time;
s505, when an alarm signal is received, the video which is started to be recorded is an alarm video, and the linkage video which is set in S502, namely the video in a period of time before and after the alarm and the video in the alarm are stored as the alarm video together;
s506, adding a piece of data in the database, marking the data as the alarm video, and inquiring the final alarm video according to the data in the database.
In this embodiment, after the service platform issues the alarm plan, the alarm video may be stored through cloud storage, and the outgoing alarm information, including alarm time, alarm type, alarm source, alarm location, and priority, may be checked in the event center of the client. The specific flow is shown in fig. 6, and includes the following steps:
s601, the client sends a request to the service platform to obtain a playback URL;
s602, the service platform acquires a playback URL pointing to the forwarding service management node;
s603, the RTSP request is carried out by the forwarding service management node and is redirected to a child node of the forwarding service, and the child node inquires the video file from the storage service according to the request time period;
s604, the storage service queries the cloud storage:
and S605, the cloud storage returns the file corresponding to the alarm video data in the database to the forwarding service, and the forwarding sub-node forwards the alarm video file read from the cloud storage to the client, so that the playback of the alarm video is realized.
In summary, the alarm route and the common video are stored in the same file, so that the use of space can be reduced. The mode of increasing the file ID stored in the database stores the alarm video and the common video file ID in the database, and the alarm video is recorded by increasing the data in the database, so that the read-write speed is improved.
