Problems solved by technology
However, because the existing monitoring system uses wired transmission, there are problems such as difficult wiring, long construction period and high construction cost. If criminals destroy the wired lines, the entire monitoring system will be paralyzed
In addition, due to the large number of surveillance cameras installed, wired transmission cannot achieve a 1:1 display (that is, each channel of video is equipped with a monitor), and it is impossible to arrange enough monitoring personnel to monitor all videos continuously. Therefore, Only some key videos can be monitored, and a large number of video sources can only be saved by automatic recording, and dangerous situations cannot be detected in time
Wired transmission also limits the installation location of surveillance cameras, and the flexibility of surveillance is poor

Description
technical field [0001] The invention relates to a safety monitoring device, in particular to a remote wireless intelligent monitoring system with simple installation, low cost, high reliability and convenient use. Background technique [0002] At present, many public places (such as forests, highways, factories, airports, ports, oil fields, schools, squares, hospitals, parks, residential quarters, etc.) have installed a large number of surveillance cameras (including microphones), and the collected audio and video The signal is transmitted to the monitoring center. However, because the existing monitoring system uses wired transmission, there are problems such as difficult wiring, long construction period and high construction cost. If criminals destroy the wired lines, the entire monitoring system will be paralyzed. In addition, due to the large number of surveillance cameras installed, wired transmission cannot achieve a 1:1 display (that is, each channel of video is equi...
