I’ve covered quite a few thermal cameras over the years, some standalone units and others integrated into smartphones. For the average user, they offer more than adequate performance and sensitivity.
But sometimes you need something that goes beyond “more than enough.”

This is where the Xinfrared T2S Plus comes in.
THE T2S Plus that I am testing is for Android smartphonesbut there is a separate version for iPhone which features a Lightning connector.

A few things immediately stand out about T2S Plus. It’s much larger than other standalone units I’ve used, but at less than 18 grams and one cubic inch, it fits easily into a pocket.

It also comes with a very nice carrying case to protect the device from drops, and this also contains the adapter cables.

What are adapter cables used for? Well, even though the USB-C connector fits many Android smartphones, the ports on some smartphones, especially rugged smartphones, like the Blackview 8900 Pro (just ignore the fact that this smartphone already has a built-in thermal camera) – are too buried to accept the camera.
The T2S Plus would not fit the Blackview 8900 Pro (although that smartphone has a built-in thermal camera). Adrian Kingsley-Hughes/ZDNET
This is not a problem with the T2S Plus. The cables not only offer an adapter for USB-C smartphones with a buried connector, but also for smartphones using micro-USB.

The Xtherm application (for Android And iOS) also has some nice features. I particularly like the information on the screen and the ability to drop dots to read the temperature, draw areas and even draw a line.

Then, in a fit of awkwardness, I pointed it at my face and was shocked to discover that he could “see” me breathing.

You can see my nostrils darken when I breathe in cool air and turn white when I breathe out warm air.
Yes, the T2S Plus can see your inhale and exhale.

This is super cool – I’ve tried this with other thermal cameras, and while they can “see” some changes, the quality is nowhere near what the T2S Plus can offer.
The image update speed, as well as the image quality, is simply incredible, and there is rarely any lag in the display. It is creamy, which makes troubleshooting much quicker and easier.
And if you want to get close to things – really close – rotating the focusing platform lets you do that. Here is a very close macro photo of the camera array on my iPhone 14 Pro Max.

I like Xinfrared T2S Plus a lot. It’s fast and accurate, the apps it connects to are well-designed and have professional-grade features, and the refresh rate is one of the fastest I’ve seen on a thermal camera. You can get close to things easily – making it much easier to diagnose dead components – and the quality of the result is excellent.
