Anti-drone can be categorized from a functional point of view into two parts: drone detection and detection and drone countermeasures.The main drone detection technologies are: radio-based drone detection, radar-based drone detection+, and optoelectronic-based drone detection.

Infrared night vision device is the use of photoelectric conversion technology of military night vision device. It is divided into active and passive two kinds: the former with infrared searchlight irradiation target, receive reflected infrared radiation to form an image; the latter does not emit infrared, relying on the target's own infrared radiation to form a “thermal image”, so it is also known as the “thermal imaging camera”.Visible light at night is very weak, but infrared light, which is invisible to the human eye, is abundant.

Laser rangefinder (Laser rangefinder), is the use of modulation of a certain parameter of the laser to achieve the distance measurement of the target instrument.

How to buy a good enough night vision device?Now, we start to share with you some dry facts to help people who wish to buy a night vision device to buy one that meets their requirements.Classification of night vision devices:First of all, Night Vision Devices (Night Vision Devices) are categorized into Infrared Night Vision (Infrared Night Vision), Laser Night Vision (Digital Night Vision) and Shimmer Night Vision (Image Intensifier). After testing these three types we can tell you with confidence that the Microlight Night Vision is the only night vision device worth buying.

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.

Why is it that infrared thermography can capture images in total darkness at night that we normally cannot see with the naked eye?Because everything with a temperature above absolute zero (-273°) emits infrared radiation. An infrared camera can convert the thermal radiation into a corresponding electrical signal, which is then amplified and processed to obtain a thermal image corresponding to the heat distribution on the surface of the object.

From January 16 to 18, 2024, the 25th Middle East (Dubai) International Security Equipment and Technology Exhibition (Intersec Dubai) in Dubai World Trade Center (DWTC) concluded perfectly, 1,000 exhibitors from more than 60 countries and regions to display their latest products and technological achievements in the field of security.Jovstar with “AI + security” as the core, relying on artificial intelligence, cloud computing, big data and other new generation of information technology, to the global customer focus on portable multi-functional thermal imaging camera, gun sights, micro-light ni

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.

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.
