The thermal imaging technology was initially used in the Korean War and later available only to the U.S Military.

After army force, thermal imaging cameras are widely used in firefighting to find the hotspots of the fire to rescue people, in law enforcement surveillance and other fields where heat detection is needed.

Now, thermal imaging cameras started their new beginning at home and building inspections.

Yes, thermal imaging cameras are effective and non-invasive devices for home and building inspections as they are able to detect the emitted heat energy from an object.

Using the thermal camera, one can inspect the home or building from a distance away. So you can measure the heat energy in the unsafe areas without any concern.

These thermal imaging cameras can spot the trapped moisture, water leaks, air flow, insulation, unsafe electrical boards and mainly heat loss/gain.

All the above issues will cause damage of hundreds or thousands of dollars, so doing thermal imaging home inspection regularly or before you invest in a new home will cut off these unwanted expenses.

Applications of Thermal Imaging Camera for Home Inspections

Most of the issues and potential building problems are associated with heat loss or gain. Below are some of the applications of a thermal camera in home inspection.

A thermal camera can detect the mold growing in the corner as it emits heat.

Thermal cameras let you know the energy waste. For example, by looking at the temperature, the thermal camera can tell you which part of the area in a room is not affected by air conditioning.

Trapped moisture takes a long time than other surfaces of the roof to cool down. With a thermal camera you can ‘see’ these ‘hotspots’ to find out the leaks at night.

It can locate the faults in the wall and roofs of the building. The thermal camera can detect,

• Airflow
• Air Leaks
• Roof insulation
• Overheating circuits, unplugged wires, and sockets.

The problems in hidden pipes or pipes behind walls can be detected without affecting the overall plumbing system.

How to Choose the Best Thermal Imaging Camera for Home Inspections

Are you looking for the thermal camera for home inspections of your own use? Let us help you pick the right one.

Thermal Sensor Resolution

Thermal Sensor Resolution is the reason for the clarity and critical details of a thermal image. If you choose the thermal camera with high resolution, output thermal image has a large number of pixels/unit area so more pixel areas will be clear and provide better image quality even for small objects and vice versa.

But do you know whether you need a high resolution or low resolution?

The low-resolution cameras are adequate to general inspections and maintenance around the home or garden.

If you are a professional thermal imaging inspector or one looking for a camera for your work, a high-resolution thermal camera is a must to ensure the strength of the property.

Basic or Advanced

Are you looking for the on the go thermal imager or the advanced one?

The on the go thermal imaging cameras show the temperature details while you are moving or walking around the places.

But if it is for property inspections of new or used buildings, you will need a thermal camera that has Wi-fi connectivity and intuitive software to take thermal pictures and share it with your customers and alert them.

At the end of the thermal home inspection, any professional should hand over the report which has details about the problematic areas identified in the thermal inspections and rectified images.

We have to appreciate the manufacturers like FLIR who developed thermal cameras with Wi-fi and expanded the internal memory.


As we know everyone has their own needs and budgets, so you have to compare the price of the product with your requirements.

If you are a pro-DIYer who can do a home inspection, you may not need to spend thousands of dollars on high-resolution thermal imaging camera.

Battery Life

It is based on the usage and where you will use the thermal camera. For the frequent use of the thermal camera, go for the one which has high operating time and rechargeable battery.

Final Words…

It is not surprising that the above list has more FLIR products as it is one of the undeniable thermal imaging device manufacturers.

FLIR has developed various types of thermal imaging camera to satisfy its customers. It has thermal imaging cameras as compact, pocket-sized, handheld, palm-sized, and an add-on device for the phone.

A $1000 dollar worth thermal imaging camera for home inspections can save billions of damage cost due to unaddressed heat and water leaks in the home. Thermal inspection for home ensures the health of the building as well as the safety of the residents.
