This is a good thermal camera for the price
This camera has a good resolution and frame rate for this price point. It’s a great improvement over the older Seek camera with a lighting connector that I used to own. If you plan to take pictures about a half a foot away from your target object, you might want to also purchase the “Nano Thermal Camera Macro Lens“ too. The default focus is for a room instead of close objects. The picture looks fuzzy without the lens for close objects. The app is perfectly fine for my needs. It’s simple to use, and it’s easy to permanently disable that stupid Seek advertising watermark on the pictures taken with the camera. I appreciate the automatic temperature scale on the images. It’s easy to get a spot temperature, and the high/low points. No issues were observed when I used it.

Fun toy
Works as advertised. One of the best phone attachable thermal cameras. Not the easiest to use and I'm always a bit concerned about fragility when I plug it in due to the lever on the USB C plug, but it works. Very helpful to look for leaks in the home, compare thermally insulated cups, and otherwise being a menace to the wife.

Great tool that works
The only Thermal camera I have found that actually works on Apple iPhones and Android phones both. It performs great, has lots of options in the settings and is priced very affordably which makes it a terrific value. I now have the ability to inspect my solar power systems for possible issues as well as checking my house for thermal leaks and much much more. This camera is super easy to use, and it is so small that you can just toss it in your pocket and have it with you anywhere, I would suggest putting it in something to protect it, but it is super small. It is a great tool to have around and I highly recommend it. It gets and deserves 5 stars.

Great Thermal Camera
I had the connector stay in the phone when I attempted to pull it out, breaking the camera. Seek sent a new one with no questions asked. As far as the camera, they are an incredible device. Predator vision in your pocket. I use them for detecting hidden heat on wildfires. Make cold trailing a breeze.

Awesome little camera!
I bought this on sale for a great price for which it's hard to complain! This product works great! Its very tiny, which i love! The only thing I dont like is how easily it will pick up things like reflections in a window. It can see my heat sensor through a window when trying to look outside, so you just can't see outside because of it. Iv scared the crap out of myself many times attempting to do this because all of a sudden I see my own heat signature. My dog went to the backroom outside and 10 minutes later in the dark I used this outside and could pinpoint exactly where from a good 20 yards away. If you look at my photos, the one of the person is from about 25 yards away in pitch black. If you are inside and walk, and then aim it where you walked, you can perfectly see your footprints even minutes later! 1 thing that I wish though is that it came with a case. Size is so small it could be easy to lose and im worried about scratching the lens. Overall, VERY cool camera!

Perfect upgrade.
Smaller than expected, but perfect size to fit into your pocket. Works as intended and quick to show up on the phone when plugging in. Very nice quality.

A downgrade from Compact Pro version
Was only able to get the highest resolution for iPhone 15 and up in the Nano version. Nano is crisper in some ways with the UI, but the huge downfall is the inability to change focus levels on the Nano. Using the fingers to screen method to zoom distorts the image so much that it’s not a viable choice. It did work well on the older Compact Pro versions where the zoom was controlled by turning the lens dial. The Nano only has the option to purchase a red add-on zoom device that has a number of poor reviews. Plus, who wants to keep removing and putting on a cover every time they need to zoom in on something? Normally, I’ve loved the Seek Thermal products. However, the Nano version is a disappointment due to this crucial need for zoom capability at certain times.

Good little thermal camera
Pretty good for a phone add-on thermal camera! Sensor is native 320x240, which the highest real resolution I’ve seen on these types of cameras (other advertise higher, but if you look at the product info, it’s a 256x192 sensor that is upscaled). Has a nice FOV, roughly akin to a 35mm full-frame lens, or about 1.5x in phone camera terms The app can be a bit buggy sometimes, such as not recognizing the camera when plugged in(making you unplug and replug it a few times), and saving horizontal images to Apple Photos without rotating them properly. And I do wish there was an option to get the image at sensor resolution instead of upscaled. But the app does have a large selection of palettes and overlays, plus an option to disable all overlays if you want (fun when you want to use this for photography rather than sampling temperatures)

Werkt heel vlot op mijn IPhone 16 en op de Samsung A15 van mijn vriendin. Beeldkwaliteit zeer behoorlijk voor de prijs.
