Infrared thermal imager works by infrared radiation and does not depend on visible light, so it can also be used in the dark. It belongs to the category of night vision equipment. Among the active infrared night vision goggles, passive infrared night vision goggles and low-light-level night vision goggles, infrared thermal imager belongs to passive infrared night vision goggles. Compared with active infrared night vision goggles, they have their own advantages and disadvantages, and they are not necessarily better. How to choose depends on the patrol environment and demand. Let's take a look at what night vision equipment infrared thermal imager is. 1. Can the camera be used at night?

In recent years, infrared thermal imager has developed rapidly in civil and industrial fields, and heat changes can be detected quickly by portable thermal imager. Generally, many infrared thermal cameras are used during the day, so can I use infrared thermal cameras at night?

People's observation range at night is limited, mainly because there is no reflected light when it is dark. Infrared thermal imager does not rely on visible reflected light to work, but uses infrared radiation emitted by objects to detect. No matter day or night, all objects above absolute zero will emit infrared radiation, so the use of infrared thermal imager at night will not be affected.

2. What night vision equipment is the infrared thermal imager?

Night vision equipment is used to help people see things at night. Generally, it is an instrument that uses infrared light or natural weak light to observe and aim at night. Infrared thermal imager is also a kind of night vision equipment. So what kind of night vision equipment does the infrared thermal imager belong to?

Generally speaking, night vision devices can be divided into three categories: active infrared night vision devices, passive infrared night vision devices and low-light-level night vision devices. Infrared thermal imager is a passive infrared night vision device, which does not actively emit infrared rays, but relies on the infrared radiation of the target itself to form a thermal image, so it is called "infrared thermal imager".

3. Which is better, a thermal camera or a night vision device?

1, thermal imager

The advantages of thermal imager are: it can be used in all lighting conditions and environments, and it can also track the residual heat; Disadvantages are: higher price, larger volume, heavier weight and lower definition. In the extremely low temperature environment, the imaging quality will also be affected, and the target can not be seen clearly through the glass lens.

2. Night vision equipment

The advantages of night vision device are that the image is more natural and clear, the body is stronger, the price is cheaper than that of thermal camera, and the field of vision is wider; The disadvantage is that the field of vision is easy to be blocked, and shadows, smog, hunting dogs and camouflage objects may be blocked. Only with the help of visible light can the target be seen clearly, and it cannot be used during the day.

It can be seen that the two kinds of night vision equipment have their own advantages and disadvantages. How to choose mainly depends on the patrol environment, demand budget and lighting factors.
