Can you see the car clearly by monitoring the infrared camera? In the underground garage, the car is covered with film, but it is not too deep.

Cameras are generally located in corners, entrances and exits, in short, places with a wide field of vision, and general underground parking garages will have cameras. The power supply of infrared camera is low, and there are two kinds of infrared rays used: near infrared rays or short-wave infrared rays, the wavelength of which is 0.76 ~ 1.5 micron, and it penetrates deeply into human tissues, about 5 ~10 mm;

Far infrared rays or long-wave infrared rays, the wavelength of which is 1.5 ~ 400 microns, are mostly absorbed by superficial skin, and the depth of penetration into tissues is less than 2mm. Enhance the ability to capture images at night. So most users need an infrared camera to pursue a strong photo effect.

Expand the data, but in practice, the infrared camera often has a clear picture during the day, but the picture becomes blurred under the condition of infrared light. This is because the wavelengths of visible light and infrared light (IR light) are different. Different wavelengths will lead to different focal plane positions, resulting in virtual focus and image blur.

The infrared lens adopts the latest optical design methods, special optical glass materials, special transition films and materials and other advanced technologies to eliminate the focal plane shift of visible light and infrared light.

The special optical glass material solves the problem of clear imaging of infrared camera, so that the light from visible light to infrared light can be imaged at the same focal plane position, and a clear image can be realized. Special crossing membrane technology allows infrared light to pass as much as possible; Multi-layer coating can also minimize the occurrence of ghost and flash under backlight conditions, and even under unfavorable conditions such as backlight, high-quality pictures with relatively high contrast can be obtained.
