The video intercom system is a set of modern residential service measures in communities, providing two-way visual communication between visitors and residents, achieving dual recognition of images and voices, thereby increasing safety and reliability, saving a large amount of time, and improving work efficiency.

[0003] In the application number: CN202120287574.7, an access control video intercom device is disclosed. Through the mutual cooperation of a first motor, a threaded rod, a threaded block, a limiting plate, a second motor, a fan blade, a filter screen, a dust removal pipe, and a filter pipe, the purpose of facilitating dust removal can be achieved. Through the mutual cooperation of a support rod, a connecting plate, a spring, a connecting rod, a sleeve, a fixing plate, and an outer cylinder, the purpose of good damping performance can be achieved. However, there are still deficiencies in the above design. The fan blade blows air towards the main body of the intercom device for heat dissipation, but the use of this structure has limitations. The heat inside the main body of the intercom device cannot be exported, and the heat dissipation efficiency of the main body of the intercom device is low.

[0004] Therefore, we propose an access control video intercom device. Content of the Utility Model

The fans located inside the plug board blow air towards the heat conduction boxes, and the air flow enters the heat conduction cavity through the communication holes, blows on the heat dissipation fins, and finally the air flow blows out of the heat conduction box through the heat dissipation net, which can accelerate the air circulation speed inside the heat conduction cavity, form a circulating heat dissipation system, and further accelerate the heat dissipation efficiency of the main body of the video intercom device; the problems in the background art can be effectively solved.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

A heat conduction plate is fixedly embedded on one side of the heat conduction box close to the video intercom device body, and a mounting hole for installing a fan is provided inside the plug board.

[0010] By adopting the above technical solution, the fan located in the plug board blows air towards the heat conduction box, the air flow enters the heat conduction cavity through the communication holes, blows on the heat sinks, facilitating the heat dissipation of the heat sinks. Finally, the air flow blows out of the heat conduction box through the heat dissipation net, which can accelerate the air circulation speed inside the heat conduction cavity, form a circulating heat dissipation system, further accelerate the heat dissipation efficiency of the heat sinks, and facilitate the heat dissipation of the video intercom device body.

[0011] Specifically, two groups of the heat conduction boxes and the plug boards are arranged relatively parallel, and the two groups of heat conduction boxes are located between the two groups of plug boards.
