Verdict
The InfiRay P2 Pro is a plug-in thermal camera with an unusual focus. The listing states 256 by 192 resolution at 49,152 pixels, a 25 Hz frame rate, a measurement range of -20 to 550 C with accuracy of 2 C or 2 percent, an all-metal housing weighing 9 grams, and a magnetic macro lens supplied for close work on PCBs and microcircuits. That last item is the reason to choose it over a general purpose clip-on: electronics repair is a use case most thermal cameras handle badly.

Why a Macro Lens Changes Electronics Work
A standard thermal lens focuses at a distance measured in tens of centimetres. Point it at a circuit board and the whole board occupies the frame, so an individual resistor is a pixel or two and the shorted component you are hunting blends into everything around it.
A macro lens brings the focal distance down so a small area of the board fills the frame. Suddenly a 0603 resistor is dozens of pixels, and the component that is dissipating power announces itself immediately. For anyone repairing boards, this is the difference between thermal imaging being a curiosity and being the fastest diagnostic available: power the board, look, and the fault is the bright thing.
Making the lens magnetic is a good detail. Swapping optics on a nine gram camera clipped to a phone should be one movement, and it is.
A Native Resolution Figure
The listing quotes 256 by 192 as the infrared resolution with a pixel count to match, rather than quoting an upscaled figure. Compared against the 160 by 120 detectors in entry level standalone cameras, that is a real advantage, and it is the general argument for the plug-in format: the phone supplies the expensive parts, so the money goes into the detector.
Nine Grams and All Metal
Weight matters on a plug-in camera for one reason: leverage on the phone’s port. A heavy accessory hanging off a connector stresses it every time the phone moves. Nine grams essentially removes that concern. An all-metal housing also helps thermally, since the detector’s own temperature affects its readings and a metal body sheds heat from the electronics more evenly than plastic.
A 550 C Ceiling on a Clip-On
The stated -20 to 550 C range is wide for this class and covers soldering irons, hot air tools, power semiconductors under fault conditions and general industrial surfaces as well as buildings. With an accuracy figure of 2 C or 2 percent, it is specified comparably to cameras costing considerably more.
Strengths
- Macro lens supplied, which almost no competitor includes.
- Native 256 by 192 with published accuracy and frame rate.
- Nine gram all-metal body, negligible stress on the phone port.
- Wide 550 C range for electronics and industrial work.
Limitations
- Android USB-C in the listing quoted here; confirm support for your device.
- No thermal sensitivity figure published in the bullets.
- No standalone operation; the phone is the instrument.
- No visible camera overlay stated, so images identify their subject less clearly.
How It Compares
The TOPDON TC001 Max matches the detector and adds a visible lens and Lightning support, without a macro option. For building work rather than electronics, a standalone camera such as the FLIR C5 is easier to live with. Our ranking is in the thermal imaging camera roundup.
How We Research
All figures come from the manufacturer listing. We did not run laboratory tests and publish no measurements of our own.

Frequently Asked Questions
What is the macro lens for?
PCB and microcircuit work. The listing states it allows close observation of resistance in the millimetre range, which is how you find the component that is getting hot on a board where everything is small.
What resolution does it state?
The listing states an infrared resolution of 256 by 192, described as 49,152 pixels, with a 25 Hz frame rate. That is a native figure rather than an upscaled one.
What is the accuracy?
The listing states plus or minus 2 C or plus or minus 2 percent of the measurement, whichever is greater, over a range of -4 to 1022 F.
Does it work with an iPhone?
The listing describes it as an Android Type-C camera. Check the current listing for your specific device before buying, since connector and operating system support changes.
