Omnibearing blind-zone-free surveillance and monitoring security device

Abstract

The invention provides an omnibearing blind-zone-free surveillance and monitoring security device. The omnibearing blind-zone-free surveillance and monitoring security device comprises a main camera, N auxiliary cameras and a fixing disc, wherein a camera lens of the main camera faces downwards, the N auxiliary cameras are arranged outside the side wall of the main camera and surround the main camera, the fixing disc is arranged at the upper end of the main camera, a microphone which is connected to an audio frequency amplifier integrated circuit is arranged in the main camera, a microphone hole and a multiphase signal jack are formed in the outer wall of the main camera, the microphone is arranged in the microphone hole, the video output end of the main camera, the video output ends of the auxiliary cameras and the audio output end of the audio frequency amplifier integrated circuit are all electrically connected with the multiphase signal jack, fixing holes are formed in the fixing disc, and N is a natural number which is not smaller than one. The omnibearing blind-zone-free surveillance and monitoring security device has the advantages that the design is scientific, no blind zone exists, sounds can be monitored, and the direction can be adjusted easily.

Description

technical field [0001] The invention relates to a monitoring device, in particular to an all-round non-blind zone monitoring and monitoring security device capable of monitoring in all directions. Background technique [0002] In the current prior art, the commonly used single monitoring camera generally has the problem of monitoring blind spots. The monitoring range of the camera is very limited and cannot be monitored in all directions, especially the bottom and top of the camera are always not monitored, resulting in 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 parties ...

Problems solved by technology

[0002] In the current prior art, the commonly used single monitoring camera generally has the problem of monitoring blind spots. The monitoring range of the camera is very limited and cannot be monitored in all directions, especially the bottom and top of the camera are always not monitored, resulting in blind spots; 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
