Whether you’re an inspector, a first responder, a hunter, or anything else, thermal cameras are often necessary. Thermal imaging (infrared) cameras allow you to see what the naked eye cannot see regarding heat and temperature. Most people don’t realize the number of things in the world that give off heat signatures and what they indicate.
Thermal cameras are quickly becoming the norm in many different aspects of the workplace. Home inspectors, security guards, pleasure seekers, and medical personnel worldwide have started implementing thermal cameras for various uses. However, you must choose the right camera for the right application.
This article will take a comprehensive look at the best thermal cameras of 2022. We’ll examine the type of camera you need for whatever you’re doing and what to look for in a thermal camera.
What does a Thermal Cameras do?
As the name indicates, thermal imaging cameras can pick up on heat signatures and temperature differences in objects and the atmosphere. When you point your infrared camera at something, you can tell which objects have a different temperature than others. A good temperature differential is extremely useful in many jobs and applications.
A high-quality thermal camera can even tell you the temperature of specific objects and how different they are from their surroundings. The better and more sophisticated your camera is, the more abilities it will have and the more fine-tuned. Today, thermal cameras get used for everything from warfare to healthcare and dozens of other things.
Types of Thermal Imaging Cameras
Handheld thermal cameras look similar to smartphones in size, shape, and feel. There are several handheld cameras, including two-handed ones, trigger-style, and monocular-style. The two-handed cameras are similar to cell phones, whereas monocular cameras look more like single-lens binoculars.
Handheld cameras of all kinds get used in nearly all aspects of life that require thermal imaging. They’re the most utilized and most popular thermal imaging cameras, and they apply to whatever you’re doing where you can benefit from infrared technology.
Trigger-style thermal cameras are held with one hand and are extremely versatile. Home inspectors, first responders, security guards, and similar jobs love trigger-style thermal cameras. You only need one hand to operate the camera, so the other hand is free to hold something else. Trigger-style cameras are a type of handheld camera but are becoming popular enough to deserve their section.
Another type of thermal imaging device that’s getting extremely popular is smartphone attachments. Thermal imaging smartphone attachments are small, compact, and plugged directly into the bottom of your cell phone.
While they lack certain capabilities that larger devices have, they’re a favorite for homeowners, hunters, and others who want thermal imaging capabilities but don’t need it to the extent of a professional.
Drones are another popular option when it comes to thermal imaging. Drones are used mostly by the military, police, and similar lines of work because of their ability to remain undetected at great heights while giving off heat signatures on the ground.
Drones also get used in more peaceful walks of life, such as home and residential inspections and the mineral industry. They can inspect roofs, fields, and other large areas from up high and get a better overall view of what’s going on below.
Who Needs a Thermal Camera?
If you haven’t figured it out yet, thermal cameras get used by many different professions. Their usefulness in detecting microscopic leaks and temperature differentials is second to none. Here are some specific professions that utilize the modern wonder of thermal cameras.
Home inspectors have recently started to use thermal cameras to detect various anomalies. Thermal cameras can detect the temperature difference if walls, ceilings, or attics are low on insulation in certain areas. They will also detect problems with a home’s HVAC system and the various components that make it up.
Since inspectors started using thermal cameras, they have quickly become the norm for serious home inspectors.
Thermal cameras can detect water leaks, water temperature, and temperature imbalances in a plumbing system. For these reasons, plumbers have started utilizing them and improving their work in ways never before.
Water heaters should have an internal temperature of 120 to 140 degrees Fahrenheit. Detecting the internal temperature is difficult unless you have a thermal camera to see right through the outer tank. The same goes for plumbing pipes and for detecting water leaks.
A thermal camera will note the temperature difference between water leaking from a pipe and the water inside the pipe. A high-quality thermal camera will even pinpoint the exact origin of the leak!
Electrical work is an area where thermal cameras are extremely useful. You can’t see it with the naked eye, but electrical wires that have electricity running through them are extremely hot. Thermal cameras can see electrical shorts or areas where the wires are hotter than they should be, which is a fire hazard.
Thermal cameras can also detect areas of high resistance, loose connections, and other anomalies that could damage your electrical system. On a commercial level, power line workers can use thermal imaging cameras for the same reasons but on a larger scale.
Just as electricians, plumbers, and home inspectors use thermal cameras to detect problems around a house or building. Contractors can use them for the same purposes. Contractors who use thermal cameras can detect problems before a home inspector has the chance. Catching problems ahead of time will save a ton of red tape and headaches from a failed inspection.
If you want to step up as a realtor, a thermal camera is a great way to do it! A thermal camera will help you give prospective buyers and sellers a clear idea of problem areas to be aware of. Doors and windows that aren’t sealing properly, roof leaks, termite infestations, and many other hazards are detectable with a thermal camera. You’ll be the envy of the office thanks to your new thermal imaging camera.
We mentioned before that thermal cameras can mean the difference between life and death, and we meant it. First responders such as firefighters use thermal imaging cameras to see through smoke inside a burning building. Thermal cameras can see through the noise and obstacles to detect physical heat signatures needing saving.
Police officers incorporate thermal cameras when they’re in search of a suspect. They use thermal cameras in many of the same ways that firefighters do in that they can see through smoke and darkness and detect heat signatures. Thermal cameras are also useful during crime scene investigations and rescue operations.
Security and Military Use
One of the top uses for thermal imaging is in the fields of security and warfare. The military uses thermal cameras on drones, handheld devices, and monocular devices to get an advantage on their enemy. They also use vehicle-mounted thermal cameras for active thermal detection.
On a local level, security guards and modern security systems also have thermal imaging capabilities. Thermal cameras can uncover hotspots and heat signatures that the naked eye cannot see at night.
During viral outbreaks such as SARS, ebola, and the recent coronavirus, thermal cameras were useful for detecting fevers in people. A high-quality camera can give an accurate temperature reading within one or two degrees of correctness. They can also detect when someone’s body temperature is slightly higher than it should, indicating a fever.
