1. Does the night vision device need batteries?

Answer: All night vision devices need battery power supply, some are CR123A lithium batteries, some are ordinary 5th or 7th batteries.

2. Night vision device can be used during the day?

answer: night vision device can not be used during the day! Night vision is through the electronic image tube imaging, if encountered strong light is very easy to burn out. Digital night vision device is not afraid of exposure, can be used during the day

3. What is the difference between night vision and telescope?

Answer: The most direct explanation is that the telescope can be used during the day or in a low-light environment without a power supply; while the night vision device can be observed in a completely black environment and requires a power supply to work.

What is the effect of night vision?

Answer: Most of the night vision imaging effect is green background, and a small number of digital night vision is black and white.

5. What is the difference between active night vision and passive night vision?

Answer: The night vision devices on the market are all active infrared night vision devices, which are imaged by emitting infrared rays. The disadvantage is that it is easy to expose yourself. The advantage is that you can clearly see objects in a completely black environment. More suitable for civilian use.

6. What is a digital night vision device? What are the benefits of digital night vision?

Answer: Digital night vision devices are night vision devices that can output video to support night observation. They are generally monocular and their observation effect is black and white. The advantage of digital night vision is that the imaging is high definition, the distance is far, and the video can be output.

7. Digital night vision effective distance is how far?

Answer: The effective distance of different types of night vision devices is different, generally between 100 meters and 300 meters. Taking a small object as a reference, the observation distance is within 80 meters in a completely dark environment; objects at 1000 meters can be found in an environment with starlight or moonlight.

8. What is the influence of the observation distance of the night vision device?

Answer: The observation effect and distance of the night vision device are affected by the surrounding environment and the technical parameters of the night vision device itself.

9. Why is the observation distance of night vision not far?

Answer: Because the night vision device relies on infrared transmitters to image in a completely black environment, and the infrared transmitters of all night vision devices currently emit at a distance of less than 100 meters.

10. Why is the price difference between night vision devices so big?

Answer: If the night vision instrument parameters are different, the higher the magnification and caliber, the higher the price. The price difference of night vision devices with the same parameters is mainly due to the difference in clarity.
