When is it necessary to calculate the distance factor ratio and when is it not?

Night vision equipment can be roughly categorized into three main groups:Spotting scopes - Spotting scopes are generally hand-held and can also be mounted on a weapon, they utilize a monocular (one eye) body. Since spotting scopes are handheld devices and are not worn on the body like eyepieces, they are more suitable when you want to take a more detailed look at a specific target and then return to normal observation conditions.Eyepieces - Although eyepieces can also be handheld, they are usually worn on the forehead.

Both plants, animals, humans, cars and objects emit heat. The defining characteristic of a thermal sensor is the detection of heat in response to small differences between thermal features in the image. So whether it's raining, sunny or completely dark, thermal imaging cameras provide clear thermal images. For this whole reason, thermal images characterized by high contrast are ideal for video analysis.Today, thermal imaging cameras are the monitoring solution of choice for nuclear power plants, substations, oil refineries and airports.

The most common query among thermal photographers is, “How far can I really measure with a thermal imaging camera?”It's a bit more complicated to explain, but fundamentally measuring distance depends on the resolution and field of view (FOV) of the thermal imaging camera, as follows:A thermal imaging camera with a higher resolution allows you to get more pixels on your measurement target, which improves accuracy even when measuring from a distance. A narrow field of view (e.g.

The differences between infrared thermography and low-light imaging are as follows:1. Imaging Principle:Infrared Thermography:It captures the infrared radiation emitted by objects and converts it into visible images. All objects above absolute zero emit infrared radiation, which can be detected and used to create a temperature distribution map, displaying the thermal image of the object. This technology does not require external light sources and can work in completely dark environments.Low-light Imaging:It relies on amplifying extremely weak ambient light, such as moonlight or starlight.

To better ensure the normal operation of society, the installation of surveillance is essential, but the installation of a traditional visible light surveillance without image enhancement can become difficult when forensic review and video analytics performance is required, so it is possible to install a thermal imaging camera with 7 × 24 monitoring in some important occasions.Both plants, animals, humans, cars and objects emit heat. The defining characteristic of a thermal sensor is the detection of heat in response to small differences between thermal features in the image.

When purchasing a thermal imaging camera, there are many specifications for thermal imaging cameras. Looking at a single specification does not reflect the overall performance of the camera; the combination of specifications is what determines the performance of the camera. All specifications of a thermal imaging camera are important, but you can focus on some of them to make sure you buy the right equipment.ResolutionThe resolution of a thermal imaging camera is how many pixels are in the camera's detector.

In industry, the provision of reliable power is critical to equipment safety and personnel safety, and it ensures the smooth operation of motors, transformers, conductors, power cables, and other types of electrical installations.There are often a large number of switches, contacts, wiring, casing clamps and other components in the electrical equipment system, which cause abnormal overheating points due to poor contact, corrosion, internal abnormalities and other reasons, jeopardizing the normal operation of the equipment as well as the safety of the power supply, and leading to electrical fir
