Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] The method for locking video surveillance video data locks the video that needs to be protected, and records the basic description information of the locked video, the storage location of the locked video data on the medium, and the effective time of the locked video through the database. Interval information; when the remaining disk space is insufficient, the locked video data information in the database is retrieved, and the corresponding locked disk chunk position is skipped without overwriting to protect the locked video data; at the same time, the locked information is continuously updated, according to the The locking effect and end locking time set by the locking video data, the locking effect and automatic unlocking function after reaching the specified time; in addition, the video can be unlocked according to the user's unlocking request.

Abstract

The invention relates to a method of locking video surveillance video data. The method comprises the steps of locking a video to be seriously protected; retrieving locked record data information in a database; and protecting the locked video data in such a way of not covering a chunk of a corresponding locked magnetic disc. According to the method of locking video surveillance video data provided by the invention, when the free space of a storage medium is insufficient, the video recording data needs to be covered circularly, the records of the locked video data information in the data base can be retrieved by adopting a way of formulating the video data locking, and the position of the chunk of the corresponding locked magnetic disc cannot be covered, so as to realize the protection on the locked video data; in addition, the functions of locking to take effect and automatically unlocking after the appointed time is reached can be realized.

Description

technical field [0001] The invention relates to the technical fields of video data storage, security and intelligent transportation, in particular to a method for locking video surveillance video data. Background technique [0002] In recent years, with the continuous development of network technology and the diversification of economy and lifestyle, video surveillance business has received extensive attention. The video surveillance service can provide users with services such as remote image transmission, cloud mirror control operation, video storage management, and alarm linkage notification. However, because the video surveillance business is limited by the network connection status, the cost of use and maintenance is high, and the regions or departments with low security level requirements do not need functions such as remote image transmission, cloud mirror control operation, and alarm linkage notification. Or the department adopts the method of real-time monitoring a...
