What to consider when buying night vision device?

When purchasing a night vision device, you should pay attention to the performance parameters and technical indicators of the night vision device. If you want to buy a good night vision device, you must choose the right product according to your needs and budget. Things to consider when purchasing a night vision device. The factors are:
1. Image intensifier tube
The image intensifier tube directly determines the level of the night vision device. Be sure to confirm it when buying. Generally, there is a clear mark on the product packaging and machine which generation of image intensifier tube it is. You can buy it according to your needs; however, it should be noted that The application industries of fourth-generation and higher-level night vision devices are restricted in China, and sales in the civilian industry are usually not allowed.
2. Magnification and lens
Carefully check the magnification and lens of the night vision device. For night vision devices of the same image intensifier tube level, the larger the diameter, the farther the viewing distance, and the better the effect.
3. Image enhancement technology
Night vision devices with this technology will have better and clearer images under the same conditions. When purchasing, you can ask whether they are equipped with this technology.
4. Infrared transmitter
Night vision devices are applied based on the principle of infrared thermal imaging. The performance of the infrared emitter directly affects the imaging quality. The intensity of the infrared and the distance of the irradiation directly affect the viewing effect.
5. Resolution
The higher the resolution, the clearer the displayed image and the higher the target recognition, which directly determines the viewing distance.
