The difference between night vision and infrared cameras
Night vision devices and infrared cameras are both very useful tools in night observation and monitoring. Although both of them can be used for observation in low visible light conditions, there are some important differences between them. This article will ** the difference between night vision devices and infrared cameras.
First of all, a night vision device is a device that transforms a faint light into a bright image by magnifying natural light. Night vision devices work on the principle of the photoelectric effect, which converts the received light into electrical signals, which are then amplified to generate an image. Therefore, night vision devices usually require a certain amount of ambient light when they are used, and if there is no light at all, the night vision device will not work.
In contrast, an infrared camera generates a thermal image by sensing the infrared rays emitted or reflected by the target object. Infrared cameras are not limited by ambient light and can capture the animal's activity even in complete darkness. This is because infrared light is a part of electromagnetic waves, and unlike visible light, it is not perceptible to the human eye. Infrared cameras are able to capture these invisible rays and convert them into thermal images.
Secondly, night vision and infrared cameras also differ in image quality. Night vision devices typically present images in black and white or green, while infrared cameras can capture the thermal radiation emitted by the animal's body and display it in false color. As a result, infrared cameras are more accurate in identifying and distinguishing between different animals or objects.
Finally, there are also differences in the use of night vision devices and infrared cameras. Night vision devices are generally less expensive than infrared cameras and are suitable for use by individual users and ordinary observers. Infrared cameras, on the other hand, are more suitable for professional researchers and wildlife conservationists because they can provide more accurate and detailed information.
In conclusion, both night vision devices and infrared cameras have their unique applications in night observation and monitoring. While they can both be used for observation in low visible light conditions, they differ in how they work, image quality,** and how they are used. It is very important to choose the right tool according to the actual needs and purpose of use.
