Astonishingly quick thermal diagnostics for anything regarding heat.
We use this outstanding thermal camera at my college for auto techs and electricians for scanning overheating circuits.Just because one connection has has been/is overheating, does not mean that other connections in the same circuit are not also overheating. Therefore, this very high quality thermal imaging camera really gets the job done thoroughly, and identifies the trouble spots ***instantly***!!!The value you get for what this does for you is astonishing!It has plenty of storage capacity, and is very, very easy to set up and use.When you are seen using this, you are seen to be professional.

This thing is quite worth the investment. Fun to play with.
I got this used. Looked like it was never taken out of the packaging. The image quality is spectacular with the enhancement (outlines of edges and such), really helps identify hotspots easily. Came with a nice hard case and USB-A to USB-C Cable. The image is neat with the little cross hairs reticle and temp reading, allowing pinpoint temp identification. I trust this unit more than I do a cheap infrared thermometer. Automatically calibrates, and color changes as hotter items get introduced to view. I do not regret buying this thing. The worst I see with it is it doesn’t reach through my other box cover. The rubber is just too thick. So I ordered an 80 gbps male to female USB-C data cable and will use it unattached from phone. I keep hitting the power button due to it being centered on the unit, and me holding it on phone tightly. Image clarity is spectacular. And allows you to see at night. It isn’t hard to use, easy to deploy. I don’t have a full hour into its use. Definitely gonna be handy for hotspots on engines! Picture shows an LED 100 watt equivalent. It’s neat to look at what has heat and what don’t. If you are considering getting one, it is worth $200.

Great budget thermal camera, trusted brand
Works great for my iPhone 15. Only downside is if the screen times out it’ll take awhile to reconnect. Useful for finding air leaks on doors. Worth the money, FLIR is a known quality brand. Nice case so it’s compact and not too heavy to keep on your phone. Perfect for a DIY user.

The FLIR ONE Gen 3 is more than just a gadget
### **FLIR ONE Gen 3 Review: Unlocking a Superpower for Your Smartphone**The FLIR ONE Gen 3 is more than just a gadget; it’s a portal to an invisible world. It promises to transform your Android smartphone into a powerful thermal imaging camera, and after extensive use, I can confidently say it delivers on that promise in a way that is both accessible and profoundly impressive. This device bridges the gap between professional-grade thermal tools and consumer curiosity, resulting in a product that is as useful for a homeowner as it is for an engineer or outdoor enthusiast.**First Impressions and Design: Sleek and Integrated**Right out of the box, the FLIR ONE Gen 3 feels like a premium accessory. Its design is a significant leap forward from bulkier previous generations. It features a sleek, anodized aluminum body that feels robust yet lightweight. The clever, spring-loaded clip mechanism allows it to attach securely to a wide range of USB-C smartphones, even with a slim case on. This is a major convenience, eliminating the need to constantly remove your phone’s case. The integrated battery is a game-changer; you charge the FLIR ONE itself via its own USB-C port, so it doesn’t drain your phone’s battery during use. This thoughtful design means you can use it for extended periods without anxiety.**Performance and Image Quality: Seeing the Unseen**The core experience is, of course, the thermal vision. The FLIR ONE Gen 3 features a 80 x 60 pixel Lepton thermal sensor. While that resolution may sound low on paper, FLIR’s proprietary MSX® (Multi-Spectral Dynamic Imaging) technology is the magic that makes it work. MSX overlays key visual details from the built-in visible-light camera onto the thermal image in real-time. The result is not a blurry, abstract heat blob, but a sharp, recognizable image where you can clearly see edges, text, and outlines, all color-coded by temperature.The ability to instantly visualize heat gradients is staggering. You can:* **Precisely identify a cold draft** around a window or door frame, seeing its exact shape and intensity.* **Locate a hot spot** in an electrical panel or a circuit breaker that’s under undue stress, often before it becomes a fire hazard.* **Find studs, pipes, and radiant heating coils** hidden behind drywall or under floors.* **Discover where insulation is missing or compromised** in your attic or walls.The companion FLIR ONE app is intuitive and powerful. You can easily switch between different color palettes (Iron, Rainbow, Arctic, etc.) to best highlight the thermal contrasts you’re investigating. The ability to capture both thermal and visual images and videos, and then analyze them later, is invaluable. The spot meter gives you a precise temperature readout for any point you touch on the screen, while the area box shows you the min, max, and average temperatures within a defined zone.**Real-World Applications: From Practical to Profound**This is where the FLIR ONE transcends being a “cool toy” and becomes a genuinely useful tool.* **Home Inspection & Energy Auditing:** This is its killer app. I used it to perform a DIY energy audit of my home. I found several drafts I never knew existed, identified outlets that needed foam gaskets, and confirmed that my attic insulation was uneven. The cost savings from sealing these leaks will likely pay for the device itself over time.* **Automotive:** Diagnosing a failing wheel bearing is easy when one hub is significantly hotter than the others after a drive. You can also check radiator performance, HVAC system output, and exhaust manifold temperatures.* **Electrical Work:** For anyone doing electrical work, this is a safety essential. It instantly reveals overloaded circuits, loose connections, and failing components by their heat signature.* **Outdoor Adventures:** While hiking, I’ve used it to spot wildlife (warm-bodied animals stand out clearly against a cool background) and to find the warmest spots to camp. It’s also fascinating for seeing the residual heat of a campfire long after the flames have died down.**Limitations and Considerations**It’s important to have realistic expectations. This is not a $15,000 FLIR T-series camera. The resolution is sufficient for most consumer and prosumer tasks but won’t reveal the tiny, intricate thermal details a professional building inspector or researcher might need. Reflective surfaces like glass and polished metal can give inaccurate readings, as they often show the reflection’s temperature rather than the surface’s own temperature.The most significant consideration is the requirement for a USB-C smartphone. While this review focuses on the Android version, its performance is dependent on your phone’s processing power and screen quality.**Verdict: An Essential Tool for the Curious and Practical**The FLIR ONE Gen 3 is a triumph of consumer technology. It takes a powerful, previously unattainable sensing technology and makes it accessible, affordable, and incredibly easy to use. Its sleek, self-powered design, combined with the brilliant MSX image processing and a robust app, creates an experience that feels nothing short of futuristic.Whether you’re a homeowner looking to save on energy bills, a DIY enthusiast tackling complex projects, a mechanic, or simply a curious mind eager to see the world in a new light, the FLIR ONE Gen 3 is an outstanding investment. It doesn’t just add a feature to your phone; it grants you a genuine superpower—the ability to see heat. It is, without reservation, one of the most fascinating and practically useful tech accessories I have ever owned. Highly recommended.

Incompatible with many Android phones – not advertised
I bought the FLIR One (part # 435‑0005‑03) hoping to add thermal imaging to my workflow, but it turned out to be unusable with my phones.- Motorola Moto E22 (Mediatek MT6765V/CB Helio G37 chipset) – the camera would not pair with the FLIR app.- Samsung Galaxy A13 – I tried the same camera on this device as well, and it failed to connect there too.I contacted FLIR support, and they confirmed that the FLIR ONE Pro, Pro LT, and Gen 3 models have known connectivity issues with several Android chipsets—including the Mediatek Helio G37 and the chipset used in the Galaxy A13. The support rep pointed me a knowledge‑base article where they list some of the devices that are not usable (search for answer #2897 in flir custhelp)What’s missing: The product description makes no mention of these compatibility limits. As a result, I spent time and money on a device that I can’t actually use.Bottom line: If you have a phone with a Mediatek chipset or many other Android models (including the Samsung Galaxy A13), this camera will likely refuse to pair. Check the compatibility list before buying, or choose a different thermal camera that explicitly supports your phone. Otherwise, you may end up requesting a refund, as I did.

Nothing to Write Home About
Works great if you are OK with arching your head over the front of the camera to ensure you are seeing what you think you are. Would have been much better to design so that the lens of the attachment faces the back of the camera instead of the front.

Se avete necessità di verificare dispersioni di calore la telecamera va benissimo. La risoluzione non è altissima ma grazie alla sovrimpressione con le immagini recuperate dalla camera normale è più semplice identificare le forme degli oggetti. Se la trovate in sconto vi consiglio di comprarla perchè è super utile.

Die FLIR One ist ein beeindruckendes Gerät für iPhone-Nutzer, die an Wärmebildaufnahmen interessiert sind. Sie überzeugt durch einfache Bedienung und exzellente Bildqualität.Ich nutze sie mit einem iPhone 13 Mini vorrangig um damit feuchte Stellen am Haus zu finden. Diese sind nämlich kälter als umliegendes Mauerwerk und somit deutlich blau gefärbt in der Standartansicht. Als Foto und Video habe ich je eine unbearbeitete Aufnahme von unserem Küchenboden eingefügt wodurch man super den Verlauf der Fußbodenheizung sieht.Ein überraschendes Extra ist das mitgelieferte, robuste Case, das nicht in der Produktbeschreibung stand. Dieses Case bietet ausgezeichneten Schutz.Bei der Lieferung bemerkte ich kleine schwarze Fusseln in der Verpackung. Zunächst dachte ich, es könnte sich um ein bereits benutztes Produkt handeln, aber das Gerät war in perfektem Zustand.Die FLIR One funktioniert toll mit verschiedenen Apps, die im App Store erhältlich sind oder direkt über die FLIR One App verlinkt werden. Die Kfz-Inspektions-App mit Tutorials ist besonders hilfreich, und mit der Desktop-Version gibt es noch mehr Möglichkeiten.Ein wichtiger Tipp für Nutzer, die ihr iPhone mit MagSafe laden: Die Ladebuchse kann durch Staub und Schmutz aus der Hosentasche verstopfen, ohne dass man es merkt. Kleine Silikonverdeckungen für den Lightning-Connector können helfen, die Verbindung zur Kamera sauber und stabil zu halten.Anders als Nachtsichtgeräte, die eine begrenzte Reichweite haben, nimmt die FLIR One Wärme ähnlich wie das menschliche Auge sichtbares Licht wahr. Ihre Reichweite ist daher vergleichbar mit dem, was wir mit unseren Augen sehen können.Die Anleitung könnte noch verbessert werden, aber insgesamt ist die FLIR One eine fantastische Wahl für jeden, der eine zuverlässige Wärmebildkamera für sein iPhone sucht. Die Version für Android kann ich nicht beurteilen.

My FLIR was delivered the other day and after letting it charge and downloading the app, I tried it out. It worked beautifully in finding the areas where I’ve been having heat loss around the house. The big result was finding a carpenter ants nest in one of our log home logs. That I have since taken care of. Would I recommend this product… Yes. It may not have all the bells and whistles of it’s more advanced siblings, but if you are looking for a simple way to find heat or cold sources this works fine.
