Ottima quello che volevo

A great thermal camera! But I had to return this unit soon after purchase. It freezes completely after a short while (2-5 minutes) No hard reset possible like the Reveal model.

Pros: Good value for your money compared to Flir. Records photos and videos. Better than Flir C2/C3 but not as good as C5Cons: Accuracy at room temperate understates by about 2 deg C, so not useful for checking human temperatures. Sensor is rather noisy and grainy. Wouldn't bother with the PRO version. Image fusion doesn't look as good as Flir.

I got this to measure temperatures on my 3D printers. I was pretty unsure ordering it since I could not find any reviews for what to use for 3D printers (typically temps ranging from 25 to 275 Celsius, rarely higher) other than one person very happy with the more expensive Pro version of this camera (the only difference between this one and the Pro is the Pro has a larger IR sensor). They both go to 330 C so that's fine for my applications. I couldn't find any detailed answers about accuracy or necessary focus distance for the IR sensor -- but remembering high school physics, the IR wavelengths are very long, so focal lengths in terms of visible light wouldn't apply, nor matter -- but I could be wrong. The only info I could find was for FLIR models costing $2500 (way out of my budget). I ended up getting a "new" model from the Amazon Warehouse and so glad I did. Anyway, I am very pleased to report that within a few minutes of starting the camera up, I was able to get beautiful easy-to-understand images. I guess my expectations are lower than the folks who wanted instant response, but the only delays I experienced were about 8 seconds on startup after pressing the power button for the camera to get oriented and measure the scene to about 1 second if you move the camera to a different scene. You can get way up close and get extremely good images of thermal variation on a 3D printer hotend or heated bed. To me, this is a measurement instrument so waiting a second or two is not a bother. The attached pics show the hotend on my extremely reliable Formbot Raptor 2 printer set at 100 degrees celcius and nearing the end of cooldown at 35 degrees celcius. The camera agrees very closely with the printer's settings. I could have gotten closer, but it was doing great as is so there you go. The image closest focus distance is about 0.5 meter (just under 2 feet), so you would have to be farther away if you wanted to overlay an in-focus visible light image. Not everything is intuitive tho', and the camera comes with nothing but a little pamphlet and a USB cable (no case or detailed instructions) which is why I didn't give the full 5 stars. The buttons react differently depending on how long you hold them (capture image = short press, video = long press; power button short press = flashlight, power button long press = on/off; etc.). Not sure how the wireless works for streaming video yet, but to transfer images to your computer, just use the USB cable. Additional info: the pics were taken with a silicone sock on the hotend, which gave great results, but if you want truly accurate results from any thermal camera, you need to paint the surfaces with at least 2 coats of flat black barbecue grill paint to stop artifacts from emissivity differences due to the level of gloss and of angle. You can adjust for emissivity artifact in the camera too but it's only 4 values to choose from: matte (0.97), semi-matte (0.8), semi-glossy (0.6), glossy (0.3).

El producto me encanto, fue de las mejores inversiones para mi trabajo. Me hubiera encantado que la camara tuviera mejor definicion y que el ajuste de la imagen termica con la real, se hiciera de manera automatica. Pero una vez que se tiene practica, el ajuste se realiza muy rapido. 100% recomendable, para estas aplicaciones especializadas.

My wife bought this for our building inspection business. I do the inspections and she stays at home and does the reports and billing. This was supposed to make our report writing faster, and it does! We had a cell phone thermal imager and that’s a mess trying to move the pics around. She can now edit them and include more thermal pics in our reports, it’s a lot easier. Image quality is far beyond what I’ve had before, not sure how they do it but don’t care – it all just looks good and I can show more stuff on the camera at the site. Important when you have things to explain to the client, let’s them see exactly what I am talking about. Can’t beat this price for what you get.
