Ground panorama non-blind area monitor

Abstract

The invention provides a ground panorama non-blind area monitor which comprises a cabinet; a fixation support, one end of which is arranged on the cabinet; a bottom scene camera, which is arranged on the bottom of the inner side of the cabinet in a lens-downward manner; and N near scene cameras and M distant scene cameras which are arranged around the inner side of the cabinet. The monitoring range of the near scene cameras is corresponding to the monitoring blind areas under the distant scene cameras; and the monitoring range of the bottom scene camera is corresponding to the monitoring blind areas under the near scene cameras, N and M being natural number no less than 1. The bottom scene camera, the near scene cameras and the distant scene cameras can be miniature cameras or common cameras or large-scale cameras. The cabinet body is provided with a microphone, an audio signal jack, a power socket, and a video signal jack. The ground panorama non-blind area monitor has the advantages of scientific design, no monitor blind area, being capable of sound monitoring and easy direction adjusting.

Description

technical field [0001] The invention relates to a monitoring device, in particular to a ground panorama monitor without blind spots which can monitor in all directions. Background technique [0002] In the prior art, due to the limitation of the viewing angle, a common single surveillance camera has monitoring blind spots. The monitoring blind spots of a single camera are usually divided into left and right blind spots and lower blind spots. It is obvious that these two methods cannot completely eliminate the monitoring blind spots. And general monitoring camera lacks the collection function of sound, only has video signal output and does not have audio signal output. Due to these deficiencies, the police around the world are unable to grasp the clues that occurred in the monitoring blind area when they retrieved the surveillance video, especially the lack of important evidence of live audio that is synchronized with the video screen of the crime scene. What did the partie...

AI Technical Summary

Problems solved by technology

The monitoring blind spots of a single camera are usually divided into left and right blind spots and lower blind spots. cameras to eliminate the blind spots below each other, obviously these two methods cannot completely eliminate the blind spots in monitoring

And the general monitoring camera lacks the sound collection function, only the video signal output but no audio signal output

Due to these deficiencies, the police around the world are unable to grasp the clues that occurred in the monitoring blind area when they retrieved the surveillance video, especially the lack of important evidence of live audio that is synchronized with the video screen of the crime scene. What did the parties at the crime scene say? It is impossible to know what happened and what noises were made, which also brings great difficulty to the police to solve the case
