A feature of the P2 Pro app that I really like is that in addition to the crosshairs in the center of the image, there are two other crosshairs that find the maximum and minimum temperatures in your shot.

Then there’s the macro lens.

Putting a macro lens on the front of your camera allows you to get closer to what you’re looking at, resulting in better resolution and a more focused photo.

The software offers a lot of customization options without being stuffed with unnecessary features.

This thermal camera is great, especially for the price.

Not sure what a thermal camera can do? Here are some things you can do with a thermal camera:

• Find the electrical component that is overheating (faulty components will usually be hotter).
• We diagnose all kinds of HVAC issues, from windows that leak heat to radiators that won’t heat properly to air conditioners that won’t cool.
• Find a rechargeable battery that is dangerously overheating.
• Locate the radiator pipes under the floorboards.
• Locate the overheated power cable.
• Find cooling system problems in desktop and laptop systems.
• Spot binding brakes on cars.

My advice for learning how to use a thermal camera is to use it to look at things when they’re not malfunctioning – radiators, car brakes, electrical components, etc. That way you’ll know when things aren’t working properly because you’ll know what they look like.

Also: Every gadget geek knows: there’s always a better tool.

Thermal cameras are so useful that we use them without thinking. Just now I wanted to know if an appliance was getting power. Instead of reaching for the multimeter, I used the thermal camera to see if anything was hot inside. I could see that the part was hot, which ruled out a lot of possible problems.

I’ve tested several thermal cameras, both standalone and smartphone-mounted. Infire P2 Pro It’s great. It’s small, flexible with the macro lens, fast and accurate, and doesn’t require a separate charger.
