How To Pick The Best Infrared Camera?
Choosing the right thermal camera for you may involve numerous specifications depending on the complexity and purpose of your task.
But the first criteria is choosing the right type or form factor for your thermal camera. There are thermal cameras that can be plugged into your phone, and there are also trigger-type thermal cameras that are self-powered and easy to use with one hand.
In regards to camera specs, the thermal resolution or pixel count is also very important. The higher the resolution, the more details you will be able to 'see' in the thermal imagery.
For more details, keep reading...
Thermal Camera Types (Form Factors)
The 'Phone Connected' Thermal Camera
The first type (and probably the least expensive) is the phone connected thermal camera.
These thermal cameras are plugged into your cell phone, and it uses the battery power of your phone. They are great for hobbyists, homeowners, and professionals who won't be using them for long periods of time. The portability and ease of use are great for short term applications.
However, if you plan on using a thermal camera for a long period of time --- such as for professional home energy audits --- then a handheld 'trigger-style' camera is preferable.
Handheld Thermal Imagers
The handheld style thermal cameras are also highly portable and easy to use like the phone-connected imagers. However, these 'rectangular shaped' thermal cameras have their own battery supply so it won't drain your phone's battery life during use.
Also, these thermal cameras have their own screen which is usually larger than trigger type cameras. These thermal cameras avoid any issues of connecting the thermal camera to your phone and all of those sort of problems.
And again, these thermal cameras are also very nice for short periods of time, but for long and exhaustive applications, a trigger-style is still preferable.

Trigger Type Thermal Imagers
Trigger style infrared cameras are handheld devices that you hold with one hand as if your finger is on a trigger. There usually isn't an actual 'trigger' but it is just a way to hold the device. These devices are designed to be used for longer periods of time, and it is easier and ergonomic to use with one hand.
The downside of these types of thermal cameras is that the screens are usually smaller than the phone-connected and handheld cameras.
If you plan on using thermal cameras extensively for a home inspection, energy audit, or other professional uses --- then these cameras are likely your best option. The trigger style thermal cameras are usually the most expensive.
Choosing Thermal Resolution
Probably the most important thermal camera rating is the resolution or pixel count. Basically, the higher the resolution, the more thermal details you will see.
If you buy a IR camera with too low of a resolution, it will be difficult or impossible to pinpoint problems, and may be a waste of time. Buying a thermal camera with too high of a resolution will be needlessly expensive. The basic minimum of a thermal camera is in the 80x60 resolution range.
But for most work applications, such as home inspecting, a good resolution is in the 160x120 range.
What Are The Uses of Thermal Imaging Cameras?
Thermal cameras can be used in a wide variety of applications. Firefighters use thermal cameras to 'see' through smoke and to locate people. Law enforcement use thermal imagers to find criminals. I invite you to read my detailed guide on the uses of thermal cameras for homes.
Here are the top ways to use thermal imaging cameras in the home...
Water Leaks
Thermal cameras are great to find water leaks and moisture problems with homes. During my home inspections, water concerns are frequently a top problem with houses.
A thermal camera can quickly scan an entire area to find cold spots of likely water intrusion.
On the exterior of homes, especially flat roofing, pooled water or leaks will show up as hot spots as the sun goes down (water retains heat for a long period).
Electrical Hot Spots
Abnormal electrical connections can quickly be spotted using a thermal camera.
Loose wiring, broken insulation, and other electrical anomalies can quickly be detected using a IR camera. Especially with exposed electrical wiring, a home inspector or contractor may not want to get close to it.
With a thermal camera, you can get a bird's eye view of the electrical equipment.
Missing Insulation
Thermal cameras can be great tools to find missing or inadequate insulation and air leaks.
When I inspect an attic, a thermal camera can be a nice way to get pictures of missing or inadequate insulation.
Attic insulation ideally should be several inches above the ceiling joists, but I frequently find that older homes have areas of only a few inches of insulation.
But you can also find exterior walls with missing insulation and other areas.
Home Inspections
I have used thermal imaging cameras on many of my home inspections. If I have a suspicion about a certain area, let's say a basement wall, I can pull out my thermal camera to get a quick overview of temperatures in the area.
I can also take a picture of the infrared imagery and include it in my home inspection report. Even though I always use a moisture meter to confirm the presence of water or moisture --- using a thermographic camera can also help greatly. In addition to finding water, other uses for thermal imaging cameras can be to find electrical problems, air leaks, and missing insulation.
What Is A Thermal Imaging Camera?
A thermal imaging camera is a special type of video camera that will record videos and take pictures of the thermal landscape. Thermal cameras will convert the infrared signal (heat) into an electrical signal and display it visually on the screen.
Infrared cameras are much more popular than years ago because prices have dropped considerably. Thermographic cameras used to exceed $10,000 but can now be purchased for a few hundred dollars.
The type of light emitted by objects that is seen by thermal cameras is called infrared radiation. Infrared radiation is in the electromagnetic spectrum just like visible light --- except that it is invisible to human eyes.
When you take a picture of a room using an infrared camera, it will show different colors or shades which represents the different temperatures of the environment. Most commonly, the higher temperature objects will appear orange and yellow, and the lower temperature objects will appear blue or purple.
My guide on how thermal cameras work goes into detail on how they detect heat, focal plane arrays, and thermal blindness.
