Description

Technical Field

[0001] The present invention relates to the technical field of security monitoring equipment, and in particular to a security video monitoring system. Background Art

[0002] With the rapid development of modern society, security has become an indispensable part of people's daily life, especially in public places, residential areas, commercial facilities and key infrastructure. The application of security video surveillance system is particularly important. Traditional security video surveillance systems mostly use fixed-position cameras for monitoring. Although this fixed installation method can meet basic monitoring needs to a certain extent, it has obvious limitations in practical applications.

[0003] First of all, due to the fixed field of view of fixed cameras, they often cannot achieve full coverage of the entire monitoring area, especially when the area to be monitored is irregular in shape or has blind spots, the monitoring effect of fixed cameras will be greatly reduced. In addition, some potential safety hazards may appear at the edge of the camera's field of view or in blind spots, and fixed cameras cannot actively adjust the viewing angle to capture these key information, thereby reducing the effectiveness and safety of the monitoring system; and in the actual installation and operation and maintenance process, the installation height and angle of the camera often need to be adjusted according to the specific monitoring environment and needs. Although the traditional fixed mounting bracket has a simple structure, it often requires the use of auxiliary tools such as ladders and scaffolding during installation or maintenance, which is not only cumbersome to operate, but also has certain safety risks. Especially in some high altitudes or small spaces, the traditional installation method seems to be inadequate. Summary of the invention
