Embodiment 1

[0018] like Figure 1-2 As shown, a self-adjusting security camera based on the reversible reaction principle includes a base 1 fixedly installed on a building, a camera 2 is installed at the lower end of the base 1, and the camera 2 is surrounded by a hemispherical inner transparent cover 3 and The outer transparent cover 4 is set outside the inner transparent cover 3. The inner transparent cover 3 and the outer transparent cover 4 are fixedly connected to the base 1. Conductive rings 5 ​​whose root diameters decrease step by step from top to bottom. The conductive rings 5 ​​are made of indium tin oxide material. Indium tin oxide is conductive and transparent, so as to avoid blocking the camera 2. Multiple conductive rings 5 ​​are arranged horizontally , and the conductive ring 5 forms a closed loop, and the plurality of conductive rings 5 ​​divide the space between the inner transparent cover 3 and the outer transparent cover 4 into a plurality of annular light-transmitting ...

Embodiment 2

[0022] like image 3 As shown, the difference between this embodiment and Embodiment 1 is that the side wall of the base 1 is provided with an air vent 11 communicating with the interior of the base 1, and a fan 12 is rotatably connected to the side wall of the air vent 11. The two fan blades of 12 are all made of magnetic material and have opposite magnetic poles.

[0023] In this embodiment, when the motor 8 drives the U-shaped magnet 9 to rotate, under the action of the magnetic force, it drives the fan 12 to rotate, which speeds up the air flow at the vent 11, improves the heat exchange speed between the inside of the base 1 and the outside, and plays a role in ventilation. cooling effect.

Abstract

The invention belongs to the field of security monitoring, and in particular relates to a self-adjusting security camera based on the principle of reversible reaction, including a base fixedly installed on a building, a camera is installed at the lower end of the base, and a hemisphere surrounds the camera Shaped inner transparent cover and outer transparent cover, the outer transparent cover is set outside the inner transparent cover, the inner transparent cover and the outer transparent cover are fixedly connected with the base, the inner transparent cover and the outer transparent cover A plurality of conductive rings whose diameters gradually decrease from top to bottom are fixedly installed. The conductive rings are made of indium tin oxide material. The plurality of conductive rings divide the space between the inner transparent cover and the outer transparent cover into multiple A plurality of ring-shaped light-transmitting cavities are filled with a mixed gas of nitrogen dioxide and dinitrogen tetroxide. The invention can adjust the area of ​​the dark area from top to bottom of the annular transparent cavity according to the light intensity, thereby automatically adapting to the background light, sacrificing the field of vision as little as possible, and improving the definition of the object image area.

Description

technical field [0001] The invention belongs to the field of security monitoring, in particular to a self-adjusting security camera based on the principle of reversible reaction. Background technique [0002] Security camera refers to the camera used in security protection. Its main features are high sensitivity, anti-glare, small distortion, small size, long life, shock resistance, and can be monitored by remote control, so it is widely used. [0003] For the current outdoor cameras, it is generally faced with the problem of strong backlight, that is, when the direction facing the lens has a strong background light, the brightness of the captured image is extremely low, and the image processing module can only control the captured image. The overall brightness of the camera is increased, and the adjusted image definition is very limited, even blurred. For this reason, the sun visor is generally installed above the lens of the outdoor camera. When the sun visor is small, th...
