There was a time when Home Inspectors considered thermal imaging cameras as a luxury item. Today, their clients — from new Home Buyers to Real Estate Agents expect them to have a high-quality thermal camera in their inspection tools. Due to this, many up-and-coming and experienced Home Inspectors are curious about the best thermal imaging cameras.
Thermal cameras for home inspection are incredibly diverse. From handheld cameras connected to your mobile device to thermal drone cameras, today’s technology offers inspectors a wide range of thermal imaging devices.

So, how do you choose the best thermal imaging camera for your home inspection business? Are there specific specs and options that you need? Is it better to buy an expensive camera vs. being budget-conscious? And are there cameras in particular price ranges that are better than others?

These are a few questions we’ll answer in the information below. We’ll introduce you to the different types of thermal imaging cameras, what to look for when shopping for one, and the top 4 cameras for 2023.

Why You Need an Infrared Camera for Home Inspectors

A quality thermal camera is crucial because it can detect even the most subtle temperature difference. Thermal cameras are also handy in various settings and situations. Some Home Inspectors offer thermal imaging as an upgraded inspection service, while others include it for all their clients.

Listed below are some examples of where you may find them helpful.

Reason #1 — Moisture Detection

The most common use for thermal cameras is to detect moisture in hard-to-see areas of residential or commercial properties. Every Home Inspector understands that most plumbing pipes and lines are hidden behind walls or above ceilings.
Thermal imaging cameras can identify leaking pipes based on temperature differences. This permits the Home Inspector to discover and report issues to homeowners and future buyers to make repairs before the property sale.

Reason #2 — Termites and Other Insect Damage

Thermal cameras will not detect degradation in your property with no temperature difference. But they will pick up the heat signatures from a swarm of insects. Termites are common in older structures and travel in large swarms that are easy to spot with a high-quality thermal camera. Before damage occurs, termites and other pests may be detected and prevented through detection.

Reason #3 — Stucco, EIFS, and Flat Roof Inspections

Leaks are nearly impossible to detect under flat roofs, behind stucco and EIFS walls, and in damp or rotten regions. A thermal camera may save homeowners a lot of money by detecting little leaks before they can grow. Because wet and decaying places are generally colder than other locations, they will appear on a thermal imaging camera. This allows the Home Inspector to identify the position of a water leak and document it accordingly.

Reason #4 — Electrical Inspections

Thermal imaging cameras can detect heated electrical circuitry. They may also identify high heat in electrical outlets and other appliances. Excessive current flow or high resistance is generally the source of abnormal heat signatures in electric devices and wires. If they are not promptly addressed, these issues can be damaging.

3 Types of Home Inspection Infrared Cameras

Technology advancement over the past few years has made products smaller, lighter, more durable, and robust. The selection of thermal imaging cameras is exceptionally diverse – ranging from a few under $600 that are highly user-friendly to professional-level cameras exceeding a few thousand dollars.

Generally, they fall into three different categories.

Type #1 — Handheld Thermal Cameras

Handheld thermal cameras are similar to any other type of camera that you might use. You can hold them with one or two hands and take pictures or videos depending on the camera size.

The handheld thermal camera is often the preferred choice for home inspectors because it is slightly more extensive and expensive than smartphone attachments and has more capabilities.

Type #2 — Smartphone Attachment Cameras

Smartphone attachments that act as thermal cameras are becoming more popular yearly. By plugging into your phone’s USB port, these smartphone-compatible cameras let you record images and videos like you would with your iOS or Android phone camera. Even though they’re affordable and easy to use, we don’t think they should be a serious home inspector’s only tool.

Type #3 — Thermal Drone Cameras

While a thermal drone camera may not be required for every home inspection, it can make the inspector’s life much easier in specific cases—for example, roof inspections and locations high up where there is difficult access. Drones have been used for thermal imaging for a few years. Still, the technology is becoming smaller and more portable, making them easier for home inspectors.

When choosing the right thermal camera for your business, remember what you will use it for. A smartphone attachment might be the right option if you only need to inspect small areas infrequently. However, a handheld dedicated thermal camera is likely a good investment if you offer this service with all inspections.

Four Tips to Choose the Best Thermal Imaging Camera for Home Inspections

All four cameras for thermal imaging above will do the job for Home Inspectors of varying expertise. However, when shopping for the best thermal image camera for home inspections, there are a few important practical factors to consider.

Tip #1 — Consider the Size

Often, Home Inspectors neglect to consider the size of their thermal camera – something that is very important. Depending on your strength, agility, the close quarters you inspect, and how often you’ll use it, you don’t want a camera that’s too large to handle comfortably. You also want one that is easy to pack up when you aren’t using it, though convenience should never come at the expense of quality.

Tip #2 — Make Sure it has Great Resolution

The number of pixels in an image is called the resolution, and it’s a critical aspect of any high-quality thermal camera. The more pixels a thermal camera has, the better its ability to precisely locate leaks and tiny temperature changes. Low-resolution cameras might identify issues but won’t be able to show you where they are precise. This feature will make it easier to identify trouble spots and better serve your clients.

Tip #3 — Factor the Camera’s Temperature Range

The temperature is a significant area that sets handheld thermal cameras apart from smartphone attachments. Handheld cameras’ temperatures range from -13 to 700 degrees Fahrenheit, whereas smartphones only range from -4 to 250. These extreme temperatures detect electricity, plumbing, and HVAC problems.

Tip #4 — Put Accuracy Above Pricing

Accuracy knows the temperature of an object you’re measuring. An excellent thermal camera will detect temperature differences and show you the exact number. For example, a homeowner’s water heater should be 120-140 degrees. Your thermal camera can tell you the precise current temperature so you can inform the seller and buyer how the unit is performing.

Final Points on the Best Home Inspection Thermal Cameras

Every Home Inspector understands the value of using the right tools for the job. A high-quality home inspection thermal camera can make a huge difference in your ability to serve your customers accurately.

Once you complete the home inspection, you must upload and document your findings during the reporting phase. A great tool that allows all Home Inspectors to complete all their business functions is powered by HomeGauge. This includes uploading images and videos conducted by the best thermal imaging cameras.


How to read thermal images from an infrared home inspection camera?

Most infrared home inspection cameras have software that allows you to read and interpret thermal images easily. However, suppose your camera does not come with its own software. In that case, a few free thermal image processing software programs are available online that you can download and use.

What’s the average cost of thermal imaging cameras for home inspectors?

The average cost of thermal imaging cameras for home inspectors ranges from $600 to $2000. However, some high-end thermal imaging cameras can cost upwards of $5000. Most of the lower-cost thermal imaging cameras connect with smartphones – and are used as an extension to the mobile device. However, with lower price comes less reliable results.

How far can a thermal imaging camera see?

Most thermal imaging cameras can see up to 1000 feet. Still, the range and accuracy of thermal images decrease the further away an object is. However, most home inspections searching for temperature variances in walls or other home areas are completed next to the tested area. This makes the range of the camera irrelevant when properly used.

Can thermal imaging cameras see through walls?

Not exactly. A thermal imaging camera is designed to detect variances in temperature. At the same time, they can penetrate a wall to discover temperature differences; thermal imaging cameras cannot see through walls. They can, however, see thermal anomalies on the other side of a wall. Leaks, electrical shorts, or hidden mold could cause these thermal anomalies.

Can thermal imaging cameras detect mold?

Yes. Thermal imaging cameras can detect mold by finding thermal anomalies behind walls, ceilings, or under floors. The thermal camera will show a warmer area where the mold is present. However, it’s important to note that thermal imaging cameras cannot see through walls, so you may need to use other methods to confirm the presence of mold.

Can thermal imaging cameras detect water damage or leaks?

Yes. Thermal imaging cameras can detect water damage or leaks by finding thermal anomalies behind walls, ceilings, or floors. The thermal camera will show a warmer area where the water is present. However, it’s important to note that thermal imaging cameras cannot see through walls, so you may need to use other methods to confirm the presence of water leaks.

Why are thermal imaging cameras so low resolution?

The thermal images produced by thermal imaging cameras are lower resolution because the sensors in thermal cameras are only sensitive to infrared radiation, not visible light. This means thermal cameras can’t see details like color or small objects. Still, they can detect thermal anomalies that may be invisible to the naked eye.

Is there a thermal imaging camera app?

A few thermal imaging camera apps are available for smartphones and tablets. However, these apps are less accurate or reliable than dedicated thermal imaging cameras. This is because the sensors in thermal imaging cameras are designed specifically for thermal imaging, while the sensors in smartphones and tablets are not.

What’s the best digital camera for home inspections?

The best digital camera for home inspections is the one that fits your budget and meets your specific needs. However, we recommend thermal imaging cameras for home inspectors because they can see things that regular digital cameras can’t — like thermal anomalies behind walls, ceilings, or under floors.
