How many types of IR night vision are there?

The infrared(IR) technology is widely used in many areas such as agriculture, law enforcement, fire rescue, military, Animal Conservation, and hunting. The thermal camera phones and IR night vision phones are used by more and more people around the world. In this section, let's learn about how many types of IR night vision are there.

There are three main types of IR night vision:

Image intensifier night vision.
Image intensifier night vision uses a vacuum tube to amplify the light that is reflected off of objects in the dark. This type of night vision is the most common and is used in a variety of applications, such as law enforcement, military, and hunting.

Digital night vision.
Digital night vision uses a digital sensor to convert infrared light into an electronic signal. This type of night vision is less expensive than image intensifier night vision and is becoming increasingly popular for consumer use.

Thermal imaging night vision.
Thermal imaging night vision uses a thermal sensor to detect heat signatures from objects in the dark. This type of night vision is more expensive than the other two types, but it can see in total darkness and is not affected by light pollution.

Each type of IR night vision has its own advantages and disadvantages. Image intensifier night vision is the most sensitive type of night vision, but it can be damaged by bright light. Digital night vision is less sensitive than image intensifier night vision, but it is not as easily damaged by bright light. Thermal imaging night vision is the least sensitive type of night vision, but it can see in total darkness and is not affected by light pollution.

The best type of IR night vision for you will depend on your needs and budget. If you need the most sensitive night vision possible, then image intensifier night vision is the best option. If you are looking for a more affordable option that is still sensitive to light, then digital night vision is a good choice. If you need to see in total darkness, then thermal imaging night vision is the best option.
