How to buy a night vision device, choose a night vision device suitable for your use from many types of night vision devices?
1. Image-increasing tube: This directly determines the level of the night vision device purchased. Be sure to confirm this information when buying to avoid infringement of rights. However,shenzhen camera manufacturer the 4th generation and higher-level night vision devices are not allowed to be sold in the civilian industry.
2. Magnification and lens: Carefully check the magnification and lens of the night vision device. In the case of night vision devices at the same intensifier tube level, in principle, the larger the aperture, the farther the observation distance, and the better the effect.
3. Image enhancement technology: Generally, night vision devices with this technology will have better image brightness and clearer under the same conditions.
4. Infrared transmitter: The quality of this performance also directly affects the image quality. Because no matter which level of night vision device the infrared auxiliary effect cannot be underestimated, especially the first-generation night vision device, the intensity of infrared and the distance of the illumination distance directly affect the viewing effect.
5. Resolution: Resolution is very important. Of course, this parameter directly reflects the level of the night vision device's image-increasing tube. The higher the resolution, the clearer the displayed image and the higher the recognition of the target, which also directly determines the viewing distance. .
