Best Thermal Cameras Buying Guide
Get your hands on a thermal camera — and it will reveal a previously unseen world of diagnostic information!
These incredible machines were once the sole domain of top-end scientists and engineers. Today, with massive advancements in technology, they’re now within the budget of DIYers, home improvers, and trade pros.
They allow you to look through walls to detect hidden pipe leaks, diagnose electrical faults before they cause a breakdown, or uncover hard-to-locate insulation gaps. They’re effortless to operate yet packed with Bluetooth and intelligent technology, and they can save you hours in analytic time.
Available in pistol grip or traditional compact camera design and at a wide range of price points dependent on their capabilities — there’s a unit for every level of skill and diagnostic project type.
When choosing your ultimate temperature camera, consider the following:
- Resolution.
- Temperature capacity.
- Connectivity.
- Memory.
- Field of view.
- Included additional features.
How Does a Thermal Inspection Camera Work?
Also known as an infrared camera, a thermal heat camera looks at your environment completely different from your eyes.
Instead of capturing the visible light spectrum, it searches for and displays infrared radiation — basically, heat energy.
Everything around you emits infrared — either more or less, depending on whether it’s hot or cold. The best thermal imager units detect this energy, and convert it into an understandable image.
This infrared thermal imaging reveals temperature variations through different colors on your camera screen — allowing you to see where heat is lost, water leaks, or electrical components are overheating.
What Can You Use a Heat Seeking Camera For?
An infrared thermal imaging camera offers a plethora of applications. If you’re a keen DIYer, you can use a thermal camera for home inspection — saving you money when you call in a professional.
For trade operators, they’re invaluable tools. From HVAC engineers to PCB builders, plumbers to insulation experts — they cut back on diagnostic hours and allow rapid pinpointing of issues.
Uses include:
- Thermal camera for water leaks.
- Diagnosing HVAC faults.
- Thermal imaging water leak detection.
- Searching for air leaks.
- Thermal imaging for home inspection.
- Checking computer components.
- Examining overheating electricals.
- Maintaining electrical boxes.
- Scrutinizing friction and energy loss.
How To Choose the Best Handheld Thermal Imaging Camera
Different users require a variety of specifications in their heat detection camera tools — depending on the projects, where they will be used, and personal preferences.
When selecting your ideal thermal imaging unit, I suggest considering the following:
Resolution
When choosing a thermal imaging device, resolution is crucial — determining the image’s clarity. The sharper the picture, the more accurately and rapidly you can identify issues — although, the more expensive the camera.
Resolution is usually measured in pixels. For example, a 256 x 192 resolution means the unit has 256 pixels horizontally and 240 pixels vertically — 49,152 total pixels.
Temperature Range
This measures the highest and lowest possible temperatures your camera can accurately measure. Whether you’re looking for the best thermal imaging camera for home inspection — or for trade applications — you need to think about its heat capabilities.
For example, if you’re checking your house for energy efficiency, a machine with a wide temperature range is perfect — it allows you to detect both heat loss and gain. But if you’re mainly concerned with locating hot spots in electrical panels, a camera with a higher maximum temperature would be more suitable.
Connectivity
The best infrared cameras possess welcome connectivity — permitting you to store, share, and analyze your thermal data and images across devices.
Typically, this is achieved through three systems:
- Wi-Fi — seamless transfer of images to smartphones, tablets, or computers on the same network, permitting you to share findings with clients or colleagues instantly.
- USB — the cheapest option, allowing direct connection to a computer for data analysis and storage.
- Bluetooth — a rapid and convenient way to transfer smaller files on compatible devices like smartphones for real-time image viewing.
Memory
The size of the memory in your thermal camera determines how much data it can store. Too little, and you’ll be limited in the amount of images and information you can capture and scrutinize.
When evaluating storage capacity, consider:
- Image and video quality — hi-res images need more storage space.
- Number of videos and images — if you’re planning on capturing numerous photos on a multitude of jobs, particularly for your trade, you need high memory.
- Removable storage — some units allow expandable storage, such as microSD.
- Connectivity — if your camera is USB, Bluetooth, or Wi-Fi compatible, you can transfer images to other devices with immense storage capabilities.
Field of View (FOV)
The FOV determines the scope your thermal camera can capture in a single image. It’s usually measured in degrees, representing the angle of the visible area. A wider FOV has a large degree value, while a narrow FOV has a smaller one.
What you require depends on your projects. A wide field of view is crucial for looking at large areas like walls, roofs, or rooms. Conversely, a narrow field of view is more suitable for specific small areas — for example, examining circuit board components.
Included Additional Features
Some models possess novel individual features that may or may not be necessary for your analytical jobs, these can include:
- Image fusion.
- Color palettes.
- Area/spot metering.
- Laser pointer.
- Voice recording.
- Video recording.
- Moisture detection.
