Method for recording video surveillance and network hard disk video recorder

Abstract

The invention discloses a video recording method for video surveillance and a network hard disk video recorder, wherein the method includes: receiving a video recording instruction, the video recording instruction includes a corresponding relationship between a channel number and a window number; displaying a picture window according to a window display mode, The displayed picture window includes a background picture window and a picture-in-picture window, and shortcut keys are displayed on the picture window interface; the opening command is received, and video data from various angles of the same monitoring scene are obtained from at least two channels, and the video data is decoded, according to The corresponding relationship displays the decoded video stream in the corresponding picture window; stores the picture data currently displayed on the display screen; receives the import instruction, reads the record file from the external device, and combines the read record text with the currently displayed picture data Make bound storage. The solution of the invention can realize multi-angle video recording, improve safety, and make video recording operation more flexible and convenient.

Description

technical field [0001] The invention relates to video surveillance technology, in particular to a video surveillance method and a network hard disk video recorder. Background technique [0002] In the video monitoring solution, the network camera collects video data, encodes it, and then sends it to the NVR through the channel between the network video recorder (NVR, Net Video Recorder); The video data is decoded, the decoded video stream is displayed, and the decoded video data is stored. [0003] For some application scenarios of video surveillance, such as interrogation scenarios such as public security, justice, and important meeting records, while video monitoring the scene, it will also perform text records, generate record files, and store the record files separately. [0004] Later, when it is necessary to view the relevant information of the interrogation scene, the stored video data and record files can be extracted. [0005] In the existing solution for recordin...

Problems solved by technology

Moreover, the existing solution only uses one network camera for data collection for each scene, and can only obtain scene images from a certain fixed angle, which cannot meet the multi-angle requirements

[0006] It can be seen that the existing video surveillance solutions have the defects of cumbersome operation, poor security, and inability to meet the needs of multi-angle video recording
