Many distributors and manufacturers now exaggerate the performance of their products in order to make their products in a competitive position, and only give the infrared distance of the products, not mentioning the clarity that customers really want. Visible distance, so that the current infrared integrated machine can nominally see more than 200 meters.
According to our company ’s years of experience in infrared products, a better infrared camera (note: here refers to a color to black and white camera) with a long-distance infrared lamp and a lens with a corresponding focal length, you can only see 150 meters at the farthest Left and right, even if you increase the number of meters of the infrared lamp, only the light intensity changes, and the distance does not change much. This is because the infrared sensitivity of the color camera is decreasing with distance. The color camera CCD The principle also determines that the infrared sensitivity of a color camera is not as good as a black and white camera. But most of the customers' actual projects used today are color-to-black and white cameras. At this time, the infrared visible distance and infrared distance are very different. Infrared visual distance is far more practical than infrared distance in engineering.
In line with the principle of good faith, we emphasize the difference between infrared visible distance and infrared distance here, and hope to help the majority of engineering and equipment manufacturers understand these two concepts, so that it is easy to choose the product that suits you.
Talk about the difference between infrared visible distance and infrared distance
Infrared distance refers to the distance reached by infrared light, from a few meters to hundreds of meters, or even a few kilometers. The visible distance at night is the clear and effective maximum distance that can be seen through the monitor, which is determined by the luminous distance of the infrared lamp, the infrared sensitivity of the camera, the infrared reflection on the scene, the quality of the power supply and the matching of the lens . The mutual result between them is just like the matching situation of the computer's CPU, memory, and chipset. The reduction of the work efficiency of any link will reduce the efficiency of the entire system.
