This tiny gadget turns your smartphone into a thermal-imaging camera

Add as a preferred source on Google

A new device takes a literal spin on hot or not — the Seek CompactPRO is a small gadget you plug into your smartphone to instantly add thermal-imaging capabilities.

Sure, the CAT S60 has built-in thermal imaging, but for those not crazy about the construction-like fashion statement, thermal imaging will soon be available on any smartphone with the Seek add-on. An update to the pricier and larger Seek Thermal Camera, the Seek CompactPro is the first add-on thermal camera with a 320 x 240 sensor array, according to the manufacturer.

The Seek CompactPRO weighs less than half an ounce and can plug into any Android or iOS camera. The compatible app allows users to see the thermal readout from the add-on’s sensor from -40 to 625 degrees Fahrenheit, and from up to 1,800 feet away. The lens gives the thermal cam a 32-degree field of view.

At a bit under $500, the thermal camera is no toy, but it’s much more affordable than most thermal cameras, used professionally in construction and other fields. The app will also see an update allowing for storing thermal images in the radiometric file format –creating a 76,800 pixel image to analyze later with all the temperature details.

“High performance thermal imaging tools used to be expensive, difficult to carry, and primarily used by few people in large industrial facilities,” said Seek Thermal’s CMO/VP of Global Marketing Tracey Benson. “It is one of the most important sensing technologies that can prevent costly damages, increase productivity, and help avoid dangerous situations in hundreds of applications. If we can make it more affordable to find problems faster and easier with high-performance imaging quality in portable size devices, we are succeeding at our mission. Our aim is to fit everyone’s budget and put smart tools into the hands of more people who can really use it.”

Compared to the original Seek Thermal Camera, the latest version has a higher resolution and smaller design, but comes at a bit higher price.

A phone thermal camera is one of those tools you don’t think you need until the first time it saves you from an expensive problem, and the Thermal Master P3 just got easier to try. For Halloween, it’s discounted with the code THERMCAM10, a 10% cut that works out to $107 off the total. It’s also fresh off a win at the 2026 Tom’s Guide AI Awards for best phone thermal camera, which is the kind of third-party nod that separates a serious tool from the cheap clip-on sensors that flood this category.

I found 8 early Prime Day camera and creator gear deals I’d actually buy
Cameras, mics and webcams are already getting cheaper before Prime Day
Prime Day Camera Deals

We are nearing Amazon's Prime Big Deal Days, which officially run October 6 and 7. But there is no need to wait until the sale begins to start looking. Early offers are already live, and camera gear is one category where I found enough worthwhile discounts to put together a proper creator-focused list.

I’ve deliberately gone wider than interchangeable-lens cameras here. There are pocket and action cameras, a 360 camera, an instant camera, two wireless microphone systems, and a pair of webcams covering very different budgets. Prices were checked on October 2, and as always with Amazon, they can move quickly.
