The FLIR ONE Pro is a compact thermal camera add-on designed specifically for iPhones with USB-C ports, starting from the iPhone 15. It offers a native infrared resolution of 160x120 pixels, enhanced up to 320x240 pixels using FLIR’s Super Resolution technology for clearer thermal images. This resolution is sufficient for spotting temperature differences but does not match professional standalone devices with higher resolution sensors. The camera measures temperatures accurately within ±3°C or ±5% in typical home and jobsite conditions, covering a useful range from about 5°C to 120°C. Its visual camera features a 640x480 resolution and includes MSX technology, which overlays real-world details on thermal images, making it easier to interpret what you’re viewing.

The device connects directly to your phone’s charging port and works seamlessly with compatible iPhones, offering user-friendly operation. It runs on a single AA battery, which is included, providing decent battery life for inspections without frequent recharging. The FLIR ONE Pro is built with a rugged design capable of withstanding drops up to 1.5 meters, making it suitable for outdoor use or on job sites. Additionally, the FLIR ONE app provides step-by-step inspection guides, helping non-experts identify common issues such as air leaks or moisture.

This camera is best suited for casual or semi-professional use rather than high-precision industrial work due to its moderate resolution and temperature range. It is compatible only with newer iPhones featuring USB-C ports, making it unavailable for Android users or owners of older iPhone models. The FLIR ONE Pro delivers a strong balance of usability, image quality, and durability for iPhone owners needing a convenient thermal camera for home inspections, maintenance, or DIY projects.
