100% Winner!!
Item arrived next day and was very well packed. I done around 2 days off and on research for ALL phone thermal cameras and I was totally won over by the high resolution. The macro lens that came with the camera fits on by a magnetic pad and is really secure. The camera has a good weight to it and made from high quality aluminium. There is a wee lens cover for the macro lens and when storing the camera, you place the macro lens over the camera to protect it. I installed the P2 Pro app with no issues and plugged the tiny wee camera into my S25 Ultra phone. Had a quick walk round the house snapping a few pics "attached" to test the general functions in different modes and wow, VERY impressed and worth every penny. As you will see from the images the radiators showed clearly as did my pet rabbits. I then tested the macro lens on an NVME SSD drive up close, about 2 - 3 cm from the lens and the images are stunning, the quality is so much better than I had expected. It's easy to adjust settings and especially liked the advanced mode where you can select up to 3 points, they show min, max and average temps. I then tried some of the other palettes, such as white hot and black hot, then tried medical, each of them has it's own benefits depending on your application to the scene you want to work with, it could be your car engine, your boiler at home, home insulation tests or even damp, yes, that's right, I found a damp patch on the opposite wall to the bathroom and will need to replace the bath seal over the weekend, but this wee camera found it. I also took an image of my laptop dock which I was surprised to see ran at 31.6 degrees Celsius! I have tried to include some pics to show a couple of the best palettes that I liked. Finally, thanks for the free cleaning cloth which was an extra surprise, it will come in handy for cleaning the lenses. I know this camera might seem a wee bit expensive for hobby use, it's very cheap when you compare the high thermal resolution when comparing to cameras that are 3 - 4 times the price, or higher with the same resolution. The final thing I would like to add is the carry case, it has a wee belt clip and the case is very sturdy with high density foam to set the camera into. The case also has a pocket with a USC-C cord for holding the camera freehand from your phone, I found this to be especially useful when using the macro function, I had both hands free to hold the camera close to a PCB to inspect. If you are looking for a low to mid range very high quality thermal camera, then I would fully recommend this product!

Great peice of kit for electronic design and debug
We needed a thermal camera for our workshop that allowed us to look in detail at surface mount electronic assemblies. After much searching and assessing online reviews we decided to pick the Infiray P2 Pro. This was the only camera we managed to find that had a macro function and could meet our demands. So far we are all very impressd with the quality of the product and the value for money when compared to higher end thermal cameras. The software seems to have lots of well thought out features most of which we are still exploring. The temperature readings match up well with our Infrared thermometer however we get far more detailed information from the P2 Pro. This tool it seems will be an invaluable addition in our ability to ensure quality design and aid in debugging and fault finding to component level. Would recomend highly.

Great little infrared camera / software needs improvements
The camera, the hardware itself, is quite good, great resolution and the camera is impressively small. I bought it for electronic board inspections. This loses a star for the software part. The android app is usable but can be a lot better, I still need to go through all the settings to see all that the app can do but first impressions were that it could be a lot better. The other thing I tried and it did not work was using the android / USB C version in an iPad Pro that has a USB C, it did not work, I found out that it is not supported which limits the device I can use this camera on. I think this can really be a 5 stars item if the software is improved.

Very good add-on IR camera.
Does the job very nicely!

The hardware is perfect, but unfortunately the software is the worst thing known to man
The hardware works fine, but the software (at least on android) is unusuably broken. The images are saved COMPRESSED ONLY. So when you use any of the functions, it generates random numbers (it has lost all the temperature data). When in live mode, it makes perfect sense. But in gallery mode, it generates complete unusable garbage. Such an amateur mistake. Such a shame.

Usb thermal camera works almost with everything
Great resolution for an absolutely tiny thermal camera. Works with android well (app a bit more tricky to find). Video was set up for a 'night drive camera'. Can also use with windows (topcon software but also vlan and standard windows camera driver). Also Linux via vlan and UVC webcam. There's some technical things to research in Linux but does work as usb thermal cam for a raspberry pi. Using a PI we've got one of these as a kind of webcam broadcasting as mjpeg.

Software not supported on current versions of Android
When I tried to download the P2 Pro App from the Play Store I was told "This app isn't available for your device because it was made for an older version of Android" (I'm running Android 16). I found an online manual for the app and it has a QR code that links to the APK which enabled me to download and then side install the app. A security risk and something I should not have to do! Now I have it working, it does what I would expect, but I can't entirely recommend it since it no longer seems to be properly supported.

Compact size and really quick interface.
Impressive little camera. Purchased to use for various fault finding as an electrician and was not disappointed. New to thermal imaging so have nothing to compare this camera to but after extensive research for somthing within my budget I think I made the right choice, this thing is small, doesn't drain your phone battery and has a suitable image quality, more then enough for what I need it for. The app is quick and camera connects within seconds whenever plugged in. Great for spotting wildlife too.

Warning: you need to install the app called TEMP MASTER, the other software (name P2 Pro) does not function properly, bet with TEMP MASTER the software functions great! (See final picture) I almost sent it back until i discovered that Temp Master fixed it. Good camera!

Franchement pour le prix je vois pas mieux, grande fourchette de mesure de température, avec la lentille macro on est capable de voir les composants individuels d'une carte mère de téléphone(Pour savoir lequel est défectueux très pratique), et le 24Hz rends la lecture des infos 100x plus compréhensible que le 9Hz auquel on est habitué. Peut servir a tout, on peut vérifier son isolation douteuse en hiver, faire son curieux avec son grille pain ou rester sérieux et vérifier que l'on dépasse pas certaines températures avec des composants électroniques.

Perfecto, lo que buscaba.Pequeño y muy buena calidad de imagen.Con la lente Macro tienes una definición increíble para pcbs con smd, y sin la lente puedes ver a distancia.

AQUOS R8 Proで動きました。今のスマホのシステムは、Android 15なので、推奨されるアプリの「P2 Pro」は使えず、代わりに「Temp Master」をインストールしました。Temp Masterを使う時に、アプリの権限として、端末内の写真と動画へのアクセス権をフルにしないと、使えないようです。 なお、付属品として、カラビナ付きの柔らかめの小さいハードケースと、USB-Cの長さ20cmほどのケーブルが1本付属していました。このケーブルはコネクターがオス-メスになっていて、これを使うとスマホからセンサー部分を離して使えます。また、スマホに挿すオスのコネクターは、90度横向きになっているので、使い勝手が良いです。

Primäre Begründung für den Kauf war die Untersuchung der Fußbodenheizung, da diese nicht an allen Stellen gleich warm wird. Die einzelnen Stränge, wenn diese nicht zu dicht nebeneinander verlaufen und damit durch die Wärmeausbreitung mit einander verschmelzen, sind zu erkennen. An der unterschiedlich warmen Zuleitung direkt nach den Ventilen konnte ich dann erkennen, dass ein Ventil defekt war. Der Unterschied war im Wärmebild direkt zu sehen, jedoch durch die geringen Vorlauftemperaturen nicht direkt zu sehen. Dieses anschauliche Beispiel zeigt für mich mein erstes Fazit nach knapp zwei Wochen: + Auflösung ist gut genug für den privaten Gebrauch, um kleinere Temperaturunterschiede zu erkennen. Auf dem einen Bild sind links meine Fußabdrücke durch dicken Socken nach wenigen Sekunden stehen auf der Fläche zu erkennen + Auch wenn die physikalische Pixelanzahl klein erscheint, ist dies zum Stand der Rezension eine der größten Auflösungen, die zu einem sinnvollen Preis von Privatanwender gekauft werden können. Es ist ausreichend für Aufnahmen, siehe bspw. die Aufnahme eines Küchengeräts (Bosch Cookit). + Die optionale Makrolinse macht Spaß und erlaubt die Aufnahme von kleinen Strukturen, siehe das Bild eines Raspberry Pis in Betrieb. + Entweder lässt man die Software selber Punkte mit Temperaturen anzeigen oder kann diese in einem separaten Messmenü selber auswählen. Sehr praktisch, wobei man für filigrane Strukturen eine ruhige Hand benötigt. o Die angezeigten Temperaturen sind nicht immer verlässlich, dies hängt jedoch mit den physikalischen Grundlagen zusammen. Hier erwarte ich auch keine präzisen Messungen, denn es kommt auf die Temperaturdifferenzen an! - Jedes Bild hat ein Wasserzeichen bzw. den Produktnamen im Bild. - Die Wahl einer selbst definierten Farbskala, also der Minimal- und Maximalwert ist nicht trivial, hier kämpfe ich noch. Dies wäre für Vergleichsbilder interessant. Fazit: Ich bin bisher begeistert von Auflösung, der Bildwiederholrate, den dargestellten Details und der Größe der Kamera. Bisher noch nicht optimal ist der Produktnamen im Bild und die manuelle Definition einer Farbskala.
