TOPDON TS001 Thermal Camera Android, 9mm Adjustable Lens, Observation Range 0.1 to 500M, 512x384 High Resolution, 25Hz, Manual Focusing for PCB boards, Pest lnspection, Outdoor, Not for IOS

I’ve owned and tested several thermal imaging devices, including handheld tools from FLIR and HIKMICRO, but none have impressed me like the TOPDON TS001 Thermal Camera for Android. I bought it initially to evaluate home insulation performance after our energy bills spiked—and I can confidently say this device has paid for itself within a few weeks. Let’s start with build quality and specs. The TS001 has a 512x384 high-resolution sensor, 9mm manual focusing lens, and a buttery-smooth 25Hz refresh rate, which isn’t just numbers—it’s something you truly feel when panning around walls, PCB boards, or even outdoor environments. Unlike entry-level models or those grainy handheld gadgets with lag and blur, this one delivers crisp, high-definition thermal views even when zooming into small resistors or checking for heat leakage around window seals. The manual focus also lets me fine-tune clarity at distances from 0.1m all the way to 500m—yes, half a kilometre! The adjustable lens is a standout. I’ve inspected blown fuses, overloaded sockets, a faulty PSU, and even a barely visible thermal bridge on the roof—all within seconds. It’s that precise. It also has auto-marked hot and cold sources, so the top three highest and lowest temperatures get tagged instantly, which helps when you're doing comparative diagnostics or scanning for animal life outdoors (spotted a fox the other night!). The app stability and updates are brilliant. You can hook this up to Android or PC (sorry, no iOS support), and the Topinfrared app lets you analyse thermal waveforms in real-time. The ability to export detailed thermal reports—ideal if you're working in trades, inspections, or even just documenting long-term home improvements—is incredibly powerful. And unlike other devices that drain batteries or require proprietary batteries, the TS001 is low-power at just 0.35W, meaning it runs cool and long on your phone. One of the first tasks I tackled was assessing our loft insulation, where the camera instantly revealed cold zones near the eaves that I’d never have spotted otherwise. Then came the underfloor heating check—a blocked loop stood out within minutes, allowing me to pinpoint the issue without tearing up flooring. We moved on to identifying draughts through window seals, and the camera clearly confirmed heat loss around our ageing uPVC frames. In the fuse box, the device detected two overheating MCBs, highlighting how easily it can prevent serious issues. When it came to heating, I used it to monitor radiator efficiency, and found two radiators that were only half-heating due to air locks. In the garage, I even tested it on my car and, to my surprise, it immediately revealed a misfiring coilpack through a subtle surface heat anomaly. The camera's role doesn’t stop with traditional household tasks. My wife and I now use it weekly to check heat distribution inside our sauna and even examine the steam room for thermal escape around the door seals. It’s equally valuable behind the scenes—we’ve used it to trace pipework in walls, avoiding costly errors during DIY projects, and to detect damp patches and cold bridges, which it does far more accurately than any standard moisture meter. I’ve used it to verify heated towel rail flow, confirming even heating patterns instantly, and also to check appliance efficiency—like discovering our fridge was leaking cold air due to a failing door seal. Beyond the home, I’ve taken it outdoors for wildlife observation, successfully spotting foxes and hedgehogs even at 100 metres distance at night. The tool also helped me track insulation performance in the garage, where recent upgrades paid off with visibly warmer internal surfaces. For solar, it was invaluable—I used it to evaluate panel efficiency, and found one cell string underperforming due to partial shading. I’ve even taken it to my desktop PC, where it gave me detailed insight into VRM and GPU hotspot temperatures during stress testing. Other uses include monitoring the boiler flue, ensuring temperatures stayed within safe parameters, and using it to balance sauna ventilation, verifying airflow and duct insulation effectiveness. One particularly clever trick? Tracing cold water pipes running through warm backgrounds—it’s precise enough to pick up the cooling line. And for late-night diagnostics, it’s flawless: night-time energy loss tests revealed window frame weaknesses I would never have seen in daylight. And perhaps my favourite feature: waveform graph analysis—when you're scanning over time or trying to detect heat build-up over a circuit, this is unbeatable. It gives a whole new dimension compared to just static snapshots. Compared to handheld FLIR One or even high-end Seek Compact Pro, this TS001 simply outperforms them all in raw clarity, control, and range. The price may seem mid-range, but in terms of output, it genuinely delivers professional-grade capability at consumer pricing. It comes with a robust EVA case, extension cable, phone holder and cleaning cloth—ready to use out of the box. One thing to note: it’s Android only, so Apple users are out of luck unless you get the TC002 version. Also, it’s built more for utility and reliability than sleek looks, which is perfect for me. I’d rather it be rugged and work flawlessly than look like a toy. As we rely entirely on electricity—powered by an air source heat pump (ASHP) and underfloor heating—there was zero room for waste. Every inefficiency, however small, directly translated into increased monthly bills, and so my aim was absolute clarity on where we were losing heat and how best to fix it. I started by scanning the entire property, inside and out, at dusk and again during colder mornings. The differences in surface temperature revealed by the thermal lens were nothing short of astonishing. One of the first and clearest findings was in our windows. Although our glazing was marketed as double-glazed and “energy-efficient”, the thermal camera painted a different picture. On the inside, I noticed stark cold streaks running vertically along the edges of the frames—particularly where the spacer bars were failing and insulation gas likely depleted. Externally, warm spots were visible where heat was bleeding out around the frame seals. I captured thermal images and shared them with a window specialist, who confirmed degraded gaskets and perished seals. We resealed some windows ourselves with appropriate silicone and draught-excluders, and replaced two key units altogether. The difference in retained warmth was immediately measurable on the TS001, and within a month, we saw a consistent drop in our evening ASHP energy draw. The walls came next. While the property is relatively modern, the thermal camera identified cold bridging along certain internal corners and ceiling junctions—areas where internal insulation was either interrupted or poorly applied. This was especially true near joist junctions in external wall cavities. The camera made it easy to highlight these issues when speaking with an insulation contractor, who later injected cavity foam in select areas and applied a foil-backed insulated plasterboard layer in our utility room. I tackled the simpler areas myself by fitting insulated switch and socket liners and applying thermal wallpaper in two north-facing rooms. Even those minor interventions registered a visible difference in the thermal profile of the room and subjectively reduced chill. Underfloor heating was another area where the TS001 earned its keep. It showed that the heating in the kitchen and hallway zones wasn’t circulating properly. One loop, in fact, was visibly colder than the others. This helped me guide a heating engineer straight to the problem: a partially closed manifold valve and trapped air. Once bled and rebalanced, the heating spread more evenly and the pump no longer had to work overtime, leading to an approximate 8–10% drop in daily electricity usage during peak heating hours. Using the camera externally also provided incredible value. The garage was supposed to be insulated, yet the thermal imaging revealed clearly warmer exterior wall panels at night, which meant internal heat was leaking. This led me to retrofit insulation boards on the internal walls and seal the roller door more effectively. In the same vein, I found that the rear wall of our ensuite bathroom, facing an exposed corner of the house, was losing significant heat. I later added a thin layer of multifoil insulation and a false stud wall, which reduced that wall’s thermal loss dramatically—confirmed through follow-up scans. All of these small, targeted interventions—led by evidence from the TS001 rather than guesswork—stacked up. Our electricity consumption from November to February dropped by roughly 22% year-on-year, despite colder weather. I was able to reduce our average daily kilowatt hour usage by optimising when and how the ASHP was triggered and ensuring each room retained heat more effectively. Importantly, I could show clear before-and-after data using the same camera, creating a visual timeline of the improvements made. It became a conversation tool with contractors and a feedback loop for my own DIY projects. If you’re an engineer, homeowner, technician, electrician, or just obsessed with smart diagnostics like me—get this. You’ll wonder how you ever lived without it.

I always fancied a thermal camera mostly for night walking in the woods and fields looking for animals that are out at night and channeling my inner springwatch, so when this camera came up I thought I would go for it, it is small attachment camera for android phone utilising the USB connection so it cannot be used as a standalone camera. It comes well packaged and has a USB cable, very limited setup instructions, and a camera clamp, it is very small about the width of a mobile phone and comes with an adjustable lens. You have to download an app from Google playstore to access features such as photo and video capture, it has various settings that can be adjusted, I just went for the default settings to see how it got on, its early days of trying it and on the positive side it is very easy to fit, recognised immediately and the app works well and is simple to use, the adjustable lens definetly sharpens the image in the distances up to about 5-10 metres but after that images become a bit blurry. It recognises heat quite well, my wife has raynauds disease so has poor circulation to her fingers and the differences in appearance between her hand and mine was noticeable. On the not so positive side this camera at time of order was £320.00 and it does seem alot of money for what it is, the build quality seems ok but not comparable to cameras of over £300 that you would purchase in store from a well known brand. I also noticed that when panning and just when using that it has buffering issues and stutters several times a minute even though I have a top end samsung camera, I am looking forward to trying it out in the woods but I am doubtful that it will cope with ranges over 10 metres for detail but will update when I get out there in some decent weather. I recognise that I am not going to get the image quality that you see on the FLIR cameras used in nature or paranormal series but hoping that it is good enough to be able to recognise animals in the woods.

​I’ve used a few popular smartphone thermal cameras before, and this one is the BEST by far. ​The image quality is instantly sharper and more detailed than the more expensive brands. It's perfect for quickly finding electrical hotspots and checking for faults during professional inspections (EICRs). ​What I Love: ​Super Clear Image: Way better resolution than competing models. ​Includes the Lead: Comes with an extension cable, so you don't have to remove your phone case to use it—huge win! ​Pro Features: Easy to change colors and calibrate for accurate readings. Powered by the phone so no dead batteries Good refresh rate for a thermal camera of this level ​It’s a professional-grade tool for a fantastic price. Highly recommend to any electrician or plumber!

Comes in a nice sturdy case to protect it. Bought it initially to check for drafts and cold spots in the house. Useful to check radiators as well, to see if any arent heating up properly, or have sludge in the bottom. Shows the realtime temps of the hottest and lowest things on screen, so no guess work. One thing to note, I had to restart both my phone and laptop after installing the software before it picked up the camera.

it has its quirks, but it works great. on some devices the app bugs out so bad that even after reinstaling from official Web page, it still refuses to work. and the pay store app doesn't work on some devices at all. it really needs an app update. for the price idk, mixed feelings, it could be great, but the mobile app drags it down. and on some windows systems works only on some usb ports

Reviewing the TC001 (Not the plus) Easy to use. Install the App and away you go. Pictures are clear and temperature appears to be accurate when tested against a temperature probe. Makes tracking down heat loss in areas a breeze! Also great for testing heating systems efficiency etc. My only criticism is that the USB-C connector could have been a tiny bit longer to allow you to use it in conjunction with a case.

Funktioniert wie beschrieben Qualität und Verarbeitung sehr gut

Très bon appareil! Très précis. Je l’ai utilisé sur mon ordinateur afin de vérifier la température des composants et celle-ci quasiment identique à celle fournie par mon ordinateur lui même!

Esta camara es ideal para revisar puentes termicos en la casa, humedades, revision del sistema de calefacion, pequeñas fugas de agua fria o caliente, problemas en la instalacion electrica, recalentamiento de aparatos etc.. Esta camara, te fusiona perfectamente la imagen termica, con la imagen real, gracias a su doble objetivo. El resultado es una imagen termica con el objeto fotografiado perfectamente definido. He comprado muchas camaras termicas y todas las he devuelto poque no cumplian las especificaciones, o no daban la calidad prometida o el angulo de vision no valia para la revision del hogar. Esta camara cumple con lo que buscaba y la recomiento totalmente.

GALAXY S24ultraのカバー付で、USB-C接続で認識使用できました。解像度など特に不満ありません。 よいではないでしょうか？

DI per se il prodotto a livello HW è ottimo, il problema è il software a corredo. Installata l'app del produttore su Android... funzionare funziona... per carità, ma alcune cose dovrebbero esse migliorate, ad esempio: è impossibile usare la telecamera in orizzontale, ma solo in verticale spesso è difficile leggere i valori di temperatura perchè essa viene mostrata sul display con colore fisso che si confonde parecchio con l'immagine sottostante. Consiglio all'azienda di migliorare il software per fare un salto di qualità.
