FAQs: Best Thermal Cameras for iPhone 2024

Is an iPhone thermal camera the best option?

By building a thermal imaging camera into the bottom of mobile phones, it may be possible to detect energy losses, water leaks, and electrical faults. When not in use, I kept one of these portable cameras in my tool pouch as a home inspector.

Home inspectors most commonly use this type of camera to inspect basements for moisture issues. You can always have a camera on hand when you need one with a phone-connected camera. If you sweep a large area for temperature anomalies, a moisture metre can confirm any suspicious areas of the basement (particularly its corners).

What powers the iPhone thermal camera?

Thermal cameras for your iPhone come in two main types.

It won’t drain your phone’s battery since one type has its own battery. However, their batteries make them bulkier. The camera will also need to be charged or it will be useless.

Thermal cameras that use your phone’s power are also available. In comparison to cameras with batteries, these iOS thermal cameras can be up to 1/4 smaller than normal thermal cameras. You will, however, run out of battery much faster than usual since it drains the battery much more quickly. The camera shouldn’t be a problem if you don’t use it for a long time.

Thermo-cameras on iPhone: How do you connect them?

The way the thermal camera is connected to your iPhone is another factor to consider. Thermal cameras from FLIR have a OneFit connector that allows for complete customizability. As a result, you can lengthen or shorten the connector according to the iPhone case. It might not be possible to connect some thermal cameras to your phone if you’re wearing a case.


Without wires, cases, or screens, you can convert your iPhone into a powerful thermal infrared camera. FLIR ONE can be connected directly to an iPhone, so you can take it anywhere. You can monitor your environment at any time. Safety hazards can be detected and prevented before they occur with infrared cameras.

A row thermogram can be obtained from infrared cameras. MSX technology makes it possible to better interpret thermal and visible spectrum images.
