[0028] Please refer toFigures 2-4 , in this embodiment, the primary adjustment assembly 4 further includes a first driving motor 401. The first driving motor 401 is fixedly installed at the right end of the inner wall of the positioning and installation mechanism main body 1. The left end of the first driving motor 401 is connected to a lead screw 408. A protrusion 402 is fixed at the end of the lead screw 408 away from the first driving motor 401. The protrusion 402 is rotatably connected to a sleeve 403. The sleeve 403 is fixed at the left end of the inner wall of the positioning and installation mechanism main body 1.

Finally, collect the sound in the monitoring area through the microphone 12, and analyze the voice content through the processor 11. Once danger is confirmed, automatically broadcast the voice alarm information through the speaker 13. At the same time, automatically send the alarm information to the preset receiving end through the wireless signal transmitter 14, so that personnel can respond in time.

[0031] Through the above steps, the installation bracket is used to facilitate the installation of the entire structure. Then, through the cooperation of the primary adjustment component and the secondary adjustment component, it is convenient to adjust the position of the video surveillance camera according to specific installation needs. And through the electrical connection between the processor and the microphone and the speaker, the voice alarm function is realized to solve the problems that the installation mechanism of the video surveillance camera lacks the voice alarm function and the one-time forming positioning method is difficult.

[0032] The above has described the embodiments of the present invention in detail with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the gist of the present invention.
