Fig. 6 is an interactive signaling diagram of a video data storage method in the prior art. In this example, the Camera is an IP Camera, the recorder is an NVR, the Server is a Record Server, and the VMS Server is for video device management. As shown in fig. 6, the method may include:

a system configuration stage:

s601, the terminal equipment sends an instruction of adding equipment to the VMS server.

S602, the VMS server sends an instruction of adding equipment to the NVR.

S603, NVR returns the equipment information to the VMS server.

S604, the VMS server returns a message that the equipment is successfully added to the NVR.

S605, the terminal equipment sends an instruction stored by the configuration center to the VMS server.

S606, the VMS Server configures the Record Server.

S607, Record Server Server returns the successful configuration message to VMS Server.

S608, the VMS server returns a message of successful configuration to the terminal equipment.

In the system configuration process, a user logs in a VMS Server through terminal equipment to perform equipment management, and establishes an association relation among an NVR (network video recorder), an IP (Internet protocol) Camera and a Record Server in the system.

When NVR is normal, the following steps are executed:

s609, the NVR sends a request for acquiring the video data to the IP Camera.

And S610, the IP Camera sends the collected video data to the NVR.

S611, the Record Server Server sends a request for acquiring the video data to the NVR.

And S612, returning the video data to the Record Server by the NVR.

When the NVR is normal, the NVR acquires video data from the IP Camera in real time for storage, and the Record Server acquires the video data from the NVR in real time for storage.

When the NVR is abnormal, the following steps are executed:

s613, the Record Server Server tries to send a request for acquiring video data to the NVR.

S614, the Record Server fails to acquire the video data.

During the abnormal period of the NVR, the NVR cannot acquire the video data from the IP Camera in real time for storage, and the Record Server cannot acquire the video data from the NVR for storage, so that the video data acquired by the IP Camera during the abnormal period of the video recorder is not stored, and the video data is lost.

The prior art has the following defects:

in the abnormal period of the NVR, the Record Server may lack the video data collected by the IP Camera in the abnormal period, and at this time, the video data in the abnormal period cannot be viewed in real time (the NVR cannot be viewed because of the abnormality).

2. When the NVR is recovered, the video data during the abnormal period of the NVR cannot be returned to the Record Server because the NVR has no video data during the abnormal period locally, thereby causing permanent loss of the video data during the abnormal period of the NVR.

The above two disadvantages directly cause the loss of video data, and cannot meet the requirement of 100% storage of video data.
