I recently had the opportunity to test out the Hti HT-203U Thermal Camera for Android Phone, designed to turn your Android smartphone into a powerful thermal imaging device. As a homeowner and outdoor enthusiast, I was intrigued by the potential applications of such a tool, from detecting energy leaks in my house to spotting wildlife during nighttime hikes. It exceeded my expectations in terms of performance, ease of use, and versatility.

I use an iPhone for my phone and this thermal camera does not support IOS or iPhones which is okay because almost everyone has access to an Android phone or tablet at least around here. The camera app is very easy to use and there are some features I'm still exploring, but I only really needed the basic functionality of being able to thermal image an object or area and take a video or some snapshots. During the summer it's great to be able to pinpoint where your insulation is lacking for thermal insulation and leakage and during the winter for outside the house to see where your heat is escaping. After installing the app I just plugged in the thermal camera and was off and running snapping pictures and measuring temperatures around my house. It's really cool to be able to see the studs and wiring in the wall, works much better than a stud finder and is quicker too. The camera showed me right away where the insulation was non-existent or severely lacking in my house and I could also make out wiring in the walls if there was a load on the circuit and the studs clearly. Kind of like X-ray vision and it's great for checking if you have mice in the house too.The speed of the camera was fine because I don't really see the need for a high frame rate. I'm not using this IR camera in a battlefield or in combat. Price wise this is in line with other thermal cameras and the device seems solidly built and worked straight out of the box. I'll use this occasionally at work when I go to different offices and can show the owner(s) where their leaks or problem areas for their buildings.

This thermal camera is great and is easy to use on my Android phone. The app has so many options that I have not had time to learn all of the features just yet. The camera is so strong that I could see my thermal image in the window from across the entire house. Crazy to believe that my thermal image was being picked up by this small camera. The camera comes with a carrying case and a cleaning cloth to keep the lens clean. This is a very professional camera and would be perfect for anyone needing any thermal imaging.

If you're looking for a good all round inspection camera this is it....
I purchased this with specific task in mind:
1. Plumbing inspection and leak detection especially when the drain is clogged...
2. Automotive and light duty Truck repair - used it to do visual inspection inside cylinders on diesel engine valve, cylinder walls and piston.. I used it to locate hidden bolts while changing out cam driven distributor on 1994 Toyota Camry..
3. Home HVAC inspection on evaporator, condenser, and supply side air registers.

I am retired and no I am not a professional.. just like fixing things and the K&F Concept Inspection Camera is soooo much better than using an inspection mirror and a flash light....plus you don't have to climb over or under things to do inspections....My wife uses it to find things that she has dropped behind the washing machine, dryer or the stove...

Have wanted a Thermal Imaging Camera for some time. Finally took the plunge. I'm using a Motorola (Lenovo) Android Phone with a USB-C Port. The device works great. I can see through the ceiling and tell where there is some insulation missing. Also, seeing a lot of issues around my front door. Taking it to other folks places to help them out. Really gives you a different perspective on the world.

Quality best inspection camera I ever own.

The camera was delivered very quickly in excellent condition. The camera works both on a Windows 11 computer with a cable and via WiFi on a Samsung Android tablet and Android smartphone. A quick start guide is included. The software can be downloaded from the Internet. The magnification can be set to exactly two levels and focused there. From these settings, the Android software enables a digital zoom of 100-200% in 20% steps using the zoom buttons on the microscope. The image quality is very good for this price.

UPDATED: Earlier Review: "Right out of the box to test use with my Android and Camera. The Android is a Galaxy J7 Crown and on that phone I had put an outer casing to protect it (since the phone on its own is very thin). The Clamp for use with a phone was able to fit snugly over both, but it was very tight. I've since been contacted K&F CONCEPT , voluntarily without my having contacted them, that they can provide a large clamp for the phone due to the phone casing. . Then tried seeing how it would work with a Canon T3i DLSR camera . As can be seen in the images , success! The portion that attaches to the bottom of camera has a nice little 'knob' for screwing in quite tightly (as does the mount for screwing the camera on). These little knobs could be easily missed. In other words, all fit on 'Tight' in all ways and the legs are very flexible. Will be interested to see all this will come down out in the field, but inside, for common use so far, great. Only thing, I'm afraid I could lose the removable part (detachable base), as it is very small (Make a mental note)." UPDATE: A new , larger mount is available that swivels from 'Landscape' to "Portrait' position without having to remove the camera mount, as it previously was. Would highly recommend this 'improved mount' , also pictured.
