Thermal cameras measure infrared radiation and convert it into an image. You can use them to see heat or temperature, making them useful for various applications, including security, surveillance, search and rescue operations, and more. In this article, we’ll explain what thermal cameras are, how they work and why you should consider investing in one of your own.

Thermal Cameras

A thermal camera is a device that can see heat. Thermal cameras use infrared light to measure how much energy objects (or people) emit. These cameras come in two main types: active and passive.

Active thermal cameras shine light onto the object of interest, while passive ones measure background radiation. Active thermal imaging devices have been used by the military since World War II when they were mounted on planes to find enemy ships at night by their heat signatures above water.

How Does A Thermal Camera Work?

A thermal camera detects infrared (IR) light, which is emitted by objects and absorbed by other objects. The IR light that is detected is then converted into an image. You can use these cameras in various applications because they are particularly sensitive to heat and can accurately measure temperature differences.

Benefits Of Thermal Cameras?

Security Tool

As a security tool, thermal cameras can help you look for intruders in your home or business. They can also be used to detect heat leaks that may indicate problems with equipment or wiring. This can help you save money by finding and fixing issues before it becomes an emergency.

Visibility Through Smoke

Thermal cameras are popular among firefighters because they make it easier to see through smoke and provide visibility when limited light is available due to power outages or other circumstances.

Wildlife Researchers

Wildlife researchers have found that thermal imaging technology allows them to better understand animal behaviour across diverse habitats worldwide, including forests and oceans, even during night-time hours when most humans would not be able to see what’s going on in these areas without special equipment such as infrared goggles.


Handheld thermal cameras are small and portable. They can be used to identify human or animal activity and movement within a controlled area. That’s why mounted thermal cameras are used for long-range observations where the equipment is positioned on a vehicle or structure that allows a view of the surrounding environment.

Monitoring Environment

Thermal cameras are also great for monitoring the environment, especially in places where there’s a lot of pollution. They can help you detect harmful gases and chemicals that may be present in your area. This is a useful tool for those who work in industrial plants or any other facility that deals with hazardous materials on a daily basis.

Military Operations

Similarly, military operations often rely on thermal imaging systems for various functions, including scanning for threats like mines buried underground during wartime scenarios. Thermal cameras can also be embedded into surveillance systems to improve situational awareness for law enforcement officers on patrol or military personnel in the field.

They can help you to see heat signatures without the need to use any light sources. This makes them an effective tool in rescue missions and police investigations. It also allows you to view things that would be impossible to see with a conventional camera, such as infrared rays emitted by animals or plants in nature. You will be able to get a clear glimpse of their bodies even when they are concealed by foliage or darkness.

Locating People And Far Objects

Moreover, thermal imaging cameras are used for many purposes but are most commonly used by law enforcement and emergency responders when searching for people who have been trapped or injured in fires or other disasters.

These imaging cameras can also be used to locate hotspots that might indicate a fire before it spreads, alerting firefighters so they can respond quickly enough to minimize damage caused by flames.

Thermal cameras are used to detect faint objects like planets or stars in outer space by measuring their radiation, such as planets or stars in outer space.

What Is Bolometer In Thermal Cameras?

A bolometer is a device that measures infrared radiation. It does this by converting the infrared radiation into an electrical current. In order to do this, a bolometer must have a material inside it that can be easily excited by infrared energy and change its electrical resistance based on the amount of incoming energy.

Bolometers are made of materials that are sensitive to infrared radiation, such as silicon carbide or mercury-cadmium telluride. An applied voltage across these materials causes their resistance
increases in proportion to increasing temperature: if we lower the temperature, they will become less resistive while increasing their resistance if heated up past room temperature.

How Do Thermal Cameras Present Images?

Thermal cameras present images as a range of grey, with cool temperatures represented by black and white at the highest temperature. The camera detects infrared radiation emitted by objects in its field of view. This radiation is emitted from the surface of the object, where it transitions from being warmer to colder than the ambient air temperature.
