Great product in the pictures I was looking around the walls showing were heat was coming in. Also made a video of me walking on stick down tile onto carpet showing it really does pick up the heat it really shows every step I took. It also shows the hottest spot with a cross hair and show in Celsius and fahrenheit temp. It's easy to use and has great image quality. Has several different screens to choose from like white hot black hot , rainbow several different screens. It's very small and compact and IT REALLY WORKS GREAT sorry Amazon wouldn't let video upload so the last picture is were I walked it works great

As someone who does DIY home repairs, I needed something that was portable but didn't sacrifice image quality, and this delivers on all fronts.Pros:Insanely Compact: It fits right in my pocket, smaller than a pack of gum. It’s perfect for throwing in the toolbox and forgetting it’s there until I need it.Plug-and-Play Easy: I just plugged it into my iPhone, opened the app, and I was scanning in seconds. The app interface is super intuitive—if you can use your phone camera, you can use this.Incredibly Clear Images: The thermal resolution is sharp, It allows for precise temperature measurements, making it simple to spot water damage or HVAC issues.If you are looking for a high-quality thermal tool without buying a heavy, expensive dedicated handheld unit, this is the way to go.

I picked up this thermal imaging camera to use with my phone, and it has exceeded expectations. the resolution is much clearer than other compact imagers I’ve tried, and the temperature detail really helps when diagnosing issues around the house. I’ve already used it for water‑leak detection, checking HVAC airflow, and even troubleshooting electrical hotspots. The image quality is sharp enough to pinpoint problems quickly, and the app is straightforward to use on both platforms. Plug‑and‑play with USB‑C is a huge plus It’s also lightweight and easy to carry, making it perfect for DIY projects or quick inspections. For homeowners, technicians, or anyone who likes having the right tool on hand, this little thermal camera delivers excellent value and performance

The Image quality is actually quite nice. I will say that I am a little less than impressed with the fact that there was no zoom capability to zoom in and out on targets. It is very easy to just slip it into a pocket and carry it wherever you need to go and then slap it right in when you need it it is a very good value for what you’re paying for. Realistically, I was not happy with the connectivity due to the fact that I have a lightning port phone and had to use an adapter absolutely love it. It works really well seven out of 10 I would buy it again.

Very simple to set up, solidly built and works well, perfect for checking out my battery and inverter cables for hot spots. Well constructed and sturdy housing feels quality. The images are substantially better resolution than just a few years ago and the sensitivity opens up a wide range of applications.

*** UPDATE 111725 *** Goyojo customer support reached out and confirmed "this model may have a potential issue" and suggested to return it and offered "20% off if I ordered a replacement package". I'm not entirely sure how the latter would help - the flaw should be inherent in all of these units until possibly a hardware/firmware revision (which may or may not resolve the issue). The rest of this review (see below the line) is still accurate and has not been substantially revised . ======================================================= If this is too long - just read this one line below: *** Does NOT work with Pixel 9 Pro XL or Pixel 10 Pro XL *** Full stop. I purchased this based on a couple of very positive Youtube videos for low priced thermal imaging cameras and also reading some of the reviews for the listing here. I should have read them all - because more than one person discovered what I did - this will NOT WORK for later model Google Pixel phones, such as the Pixel 9 Pro XL and the Pixel 10 Pro XL (which I have). You will find others reporting this issue on the official Google Pixel support forums and Reddit, etc. - I'm not sure if it doesn't work with all Android 16 phones or just those Pixels. One person said he found it worked on an old Pixel 6. I have a bunch of Pixel phones, going back to a Pixel 5, but I'm not trying any of them. Here's the thing, good or bad - Pixels are the standard bearer for the Android OS, for obvious reasons. You either work with Pixels or get dinged for not bothering to test against them. They might be the 800lb gorilla in the room you don't like, but you better understand why they ARE the 800lb gorilla, or you're in the wrong business. (tbh, after 45 years of enterprise IT and software development, I might be a bit jaded about how this sort of thing should have played out, so forgive me) I reached out to Amazon support - all the usual newbie suggestions are offered - ignore them all. They did offer to replace it or refund my purchase, of course, but I thought I'd go the extra mile - I reached out to James, the person mentioned (by email address) in this product listing for "official support" and while he was prompt to reply - the sole question he had for me ("what version of Android OS are you using?") show a complete lack of awareness for a critical component of the technology he is offering to support. A Pixel 10 shipped with Android 16 - don't ask me that if you're in the business of selling devices to connect to Android phones. Let me save you some time if people offer BS suggestions, also. Pixel 9s and 10s support OTG inherently. There is nothing to enable, disable, toggle, whatever they suggest. OTG just works and works well. It's also not a permissions issue - you can grant this device's software all the dangerous permissions in the world - that will do nothing. Don't bother with "have you cleared your cache, reinstalled the app, updated your OS, restarted your phone, etc". So because this is sort of adjacent to my career, I was within a heartbeat of downloading some diagnostic software from HIK to determine if I could see any data stream at all from the camera. I reviewed similar efforts from other devices to determine would I should expect to see in the data. Then I remembered that's too close to what I get paid to do, and it will just anger me to troubleshoot someone else's technology for a $100 device that has a ton of competitors and decided my time was better spent watching cat videos. I bought it for fun, tbh, because I collect far too many gadgets like this and never use them past the day I get them. It won't work with those phones. It will do nothing. If you plugged a cotton swab into your Pixel 9 or 10 - you will get the same result - the phone sees NOTHING. (Please don't jam a cotton swab in your phone, though. Or your ear apparently, according to everyone. So what ARE they for, then? But I digress.) Hard pass on this one, folks - even if it works for you today on your phone, older Pixel or any brand - it might not work if you upgrade your Android OS or the phone itself.

I recently picked up this thermal imaging camera that plugs directly into my smartphone, and I have been thoroughly impressed! I have an android phone and my wife has an android phone, both phones work flawlessly with this. This product also comes with an adapter for iPhones. This little gadget has really given me peace of mind and time saved. The setup was super fast and easy—just plug it in, download the app, and you're ready to go. My favorite feature with the app is that the app will start as soon as you plug in the device, no more trying to figure out what app you need to use. There are many different uses for this product and one of them is looking for hotspots and cold spot in my home. As a homeowner, this is where the camera really shines. I used it to perform a quick "energy audit" of my house. I was able to find some spots in my home that I could improve to keep the cold out in the winter and the heat out in the summer. This capability alone is worth the price, as it helps you find and fix problems. I try to also work on my own vehicles as much as possible. The camera is fantastic for diagnosing vehicle symptoms. If you're a DIY enthusiast (or like saving money), homeowner, or someone who likes to troubleshoot, this is a must-have tool. The image quality is clear enough for diagnostic work, the app is intuitive, and the portability of plugging it into your phone is unmatched. Highly recommend!
