Evaluation: InfiRay P2 Professional Thermal Digicam

It in all probability gained’t shock you to be taught that Hackaday is continually catapulted by firms that need us to overview their newest and best instruments. In any case, making it cheaper, simpler, and more practical to publish about their product than making an attempt to give you an advert marketing campaign of their very own. However if you happen to’ve been with us for some time, you’ll additionally know that inside evaluations aren’t one thing we really do fairly often.

The reason being easy: we’re solely concerned about units or merchandise that supply one thing helpful or distinctive to this neighborhood. As such, the overwhelming majority of those gives are ignored. I’ll provide you with an instance. For no matter purpose, a number of firms have tried desperately to ship me electrical bikes with five-figure value tags this 12 months. However since there was no apparent solution to flip that into helpful content material for Hackaday readers, I nonetheless moved myself as if it have been within the twentieth century. I’m joking, after all… I haven’t dared to journey a motorcycle in a decade.

So I wouldn’t thoughts telling you that, when InfiRay contacted me Their P2 Professional thermal digicam reviewThe e-mail nearly went to the trash. We’ve seen the sort of phone-based thermal digicam earlier than, they usually appear to be extra of the identical. However after taking a more in-depth have a look at the specs, equipment, and claims set forth within the advertising supplies, I assumed this is perhaps price trying out head-on.

Stand up shut and private

So what makes the P2 Professional thermal digicam totally different from many different cameras available on the market? Merely put, the mixture of the sensor’s decision of (comparatively) 256 x 192 and the addition of a magnetically connected macro lens signifies that the digicam is uniquely fitted to shut inspection of PCBs. In reality, the web site boasts that the system is ready to clearly monitor particular person 0201 SMD resistors on the board.

Whereas many of those cameras are meant for issues like discovering the chilly spots in your house, or figuring out the most well liked parts in a automotive’s engine bay, the P2 Professional is a a lot better instrument for the type of close-up, close-up work your common Hackaday reader is prone to do. After all, on the similar time, it may nonetheless do something that low-fidelity fashions can do. So even if you happen to aren’t in search of short-cut parts on SMD boards on daily basis, there are nonetheless loads of purposes for the digicam in different fields and hobbies.

Nonetheless, the ergonomics of the system shouldn’t be essentially preferrred for close-up work. The P2 Professional is so small – about 28 x 18mm – that it’s very simple to dam its view along with your hand whereas making an attempt to place the telephone accurately. It really works somewhat higher when the telephone is the other way up and the USB-C port is on high, however after all it finally ends up being awkward for its personal causes.

InfiRay will need to have seen this drawback, because it features a USB-C extension cable within the field that allows you to maneuver the digicam individually. Thanks in no small half to the digicam’s streamlined form, it solely took a couple of strains in OpenSCAD to place collectively a 3D-printed mount that might enable me to mount the digicam on an ordinary tripod. This improves the usability of the product a lot that I’d prefer to see InfiRay supply an official launch.

The P2 Professional additionally clocks in at 25 frames per second (FPS), which is considerably larger than a few of the cheaper fashions available on the market. Gradual temperature adjustments seem seamlessly, and watching warmth flow into by means of an object is as enchanting as it’s rewarding. Within the subsequent clip, I go a couple of volts by means of the 0805 resistor, and you may clearly see how the warmth generated by the resistor is drawn away by the wires as soon as the present stops flowing.

Nice {hardware}, So-So software program

NB: Since I’m utilizing the Android model of the P2 Professional, the next applies solely to the Google OS. There’s a separate model of the digicam on the iPhone and an accompanying iOS app, however since I haven’t used it, I can’t say for certain what the expertise is.

Actually, there’s nothing unhealthy I can say in regards to the P2 Professional’s {hardware} itself — it appears solidly constructed, performs nice, and even the field it is available in has nice presentation. However, the software program, whereas maintainable, may use an analogous stage of sprucing.

Getting the Android app to acknowledge the digicam typically required you to unplug it a couple of occasions, and I’ve had a number of situations the place the picture was locked from the digicam and required the app to be restarted. I additionally had points recording movies from inside the app itself, and finally had to make use of Android’s built-in display screen seize functionality to submit the above video.

Apart from the glitches, the software program is mostly good. The interface is easy, and there are various nice options resembling the power to alter colour schemes and a “picture-in-picture” mode that places the view from the telephone’s digicam onto the thermal digicam. Understand that how related the 2 views are will depend upon the digicam format of the system you’re utilizing it on.

There are many configuration and calibration choices, however the default settings all appeared to work high-quality and I by no means wanted to mess with something. Nonetheless, it’s all the time good to have these superior options and settings in case you want them.

By the way in which, for anybody who is perhaps curious, the P2 Professional chosen as an ordinary USB video system once I related it to each my Linux desktop and Chromebook. You clearly don’t get any of the superior configuration choices and it’s a uncooked 256 x 192 @ 25fps black and white video feed with no fancy upscaling just like the app needs to be, however a minimum of it really works out of the field and might be Helpful for every kind of initiatives.

Teardown outsourcing

Those that have learn my earlier evaluations will in all probability be questioning when to disassemble the P2 Professional and examine what’s inside. However I’m afraid of this factor I’m going to must undergo. It’s a small case that sticks on with some type of adhesive, and to inform you the reality, I’d fairly not destroy the factor if I will help it.

However if you happen to actually should know what he appears like on the within, the electret mics really slipped on his channel a couple of months in the past. Not surprisingly, there isn’t a lot occurring contained in the little gadget past the digicam board itself, although it’s intelligent in the way it separates the interface into its personal board to allow them to simply spawn USB-C and Lightning variations.

thermal exhibition

Because it sounds just like the type of factor you’d prefer to see in a thermal digicam overview, right here’s a random number of images I took with the system over the previous week or so.


In the long run, I have to admit that the P2 Professional actually impressed me. Not solely do the decision, body fee and macro lens make it a superb instrument for diagnosing units of all sizes and shapes – it’s simply nice enjoyable wanting on the world by means of this system. I’d like to see Android software program tightened up right here and there, however I haven’t run into any points large enough to cease me from recommending the product to others.

At $299, the InfiRay P2 Professional is priced to compete with related units from FLIR, whereas on the similar time providing larger specs in key areas. Contemplate the FLIR ONE Professional, which can price $420, however solely gives 160 x 120 decision and is way bigger and heavier. There are after all cheaper thermal digicam choices on the market, however from what we’ve seen, they’re usually extra of a fad than a great tool. When you’ve been pondering of including a thermal digicam to your toolbox however have been postpone by the price-performance ratio of what was beforehand available on the market, the P2 Professional is perhaps what you’ve been ready for.
