The InfiRay P2 Pro Xinfrared Thermal Camera for Smartphones stands out in the tech world as a notable device for capturing temperature fluctuations in different environments. Using thermal imaging technology, this camera, though expensive to some, feels like something directly from a science fiction movie. The concept of an infrared thermometer camera was once unthinkable, but is now a vital tool in multiple industries. It allows for the detection of hidden electrical faults and thermal leaks in buildings, providing a unique insight by capturing images based on temperature differences rather than light visibility. Today, such cameras come in a vast array of shapes and sizes. Among my favourites are those that can be directly connected to a phone and used in conjunction with an app.

The P2 Pro Xinfrared Thermal Camera for Smartphones by InfiRay is one such device that I had the opportunity to test recently. Its tiny size and astoundingly accurate temperature readings cannot go unnoticed. Weighing just 9g, this camera by InfiRay, a forerunner in infrared technology, is 9mm in size, making it the world’s smallest thermal camera. Despite its small size, InfiRay’s P2 Pro offers a high-performance resolution of 256 x 192 and boasts a 25Hz motion capture. The P2 Pro, available for purchase at a price of $299.00 for 1-2 units, comes fitted with a magnetic Macro Lens and features InfiRay’s AI Temp technology which ensures precise temperature measurements.

The all-metal body of the P2 Pro can register temperatures between -20~550º Celsius. Its packaging, nearly all black with the words “InfiRay P2 Pro” printed in gold, is quite plain and straightforward. Upon opening the box, you’ll find limited items — a small folder with some print materials, the camera, and the Macro lens adapter. The rest of the space within the box is occupied by foam inserts with cutouts for the camera. It seems to me that InfiRay could easily reduce the package size and still comfortably accommodate all items within it.

Software installation for the P2 Pro camera is smooth and straightforward. Simply download the app “Thermal P2”, and plug in the camera into the Lightning port to initialize it. Thanks to its flexibility, the tool gives users the ability to view thermal images in various color palettes and provides an option for more advanced users to range temperatures between two points or select an area within the camera view. The default temperature unit is set to 'Celcius', but this setting can be altered to suit user preferences.

In my testing experience, I took thermal images of my dog next to an air vent while the air conditioner was running. Comparing the results with those of a separate digital infrared thermometer, I found only a 1-degree difference for the dog and no difference for the air vent. Images are saved within the app and not the device's photo library, which I find slightly inconvenient due to my usual preference for having all images stored in the same place. In simple terms, the P2 Pro Xinfrared Thermal Camera for smartphones is both innovative and practical, providing thermal imaging technology right in your hand.
