Pocket thermal imager for phones

The InfiRay P2 Pro is a 9 g thermal camera that plugs directly into a smartphone. It delivers 256x192 infrared resolution across 49,152 pixels at 25 Hz and measures from -20 °C to 550 °C. The all-metal housing measures 27×18×9.8 mm and draws power from the handset, so no separate battery is required. Compatible with Android 9.0 and above, and iOS devices when the correct model is selected.

Step up from single-spot thermometers

A single-point IR thermometer gives one temperature reading at a time; this imager captures a full 256x192 frame 25 times per second. The jump is worth it when you need to scan a wall for missing insulation, trace a floor-heating loop, or locate a leaking water pipe in one pass. It also replaces carrying a bulky handheld thermal gun for quick HVAC or facility checks.

Suits DIY homeowners and technicians needing

Ideal for anyone who wants instant thermal vision on a device they already carry. Not suited for users who require a macro lens for extreme close-up component work, need standalone operation without a phone, or require higher native resolution than 256x192 for long-distance surveying.

The 9 g camera connects straight to the phone’s USB-C or Lightning connector with no extra cable or adapter needed.

What Android version is required before the thermal view appears on screen?

Android 9.0 or newer is required; the app will not launch on earlier releases.

How often should the 256 × 192 sensor be recalibrated to keep ±2 °C accuracy across the −20 °C to 550 °C range?

The manufacturer specifies no recalibration interval; the sensor is factory-calibrated for the life of the unit.
