I had rented a FLIR i7 and the image is not only better on this device, it also has a really nice option to vary the visible image overlay in multiple opacities - a feature the FLIR does not have! The battery life is not great but it charges fast, and at this price point, I still think it is a good value. I dropped one star because the charging/connecting port cover is annoyingly difficult to get open and keep open while you plug in the cable.
The order came 5 days after payment. Included adapter to european plug for charging. Instruction in english only. Menu languages: english, chinese, italian, german. After pressing and holding the power button turns on about 15 seconds, turns off in 5 seconds. The main plus of the model is an ir matrix with a resolution of 320x240-a very good indicator, other thermal imagers with such a matrix are much more expensive. At the moment i think this model is the best in the ratio of price/quality. Consoles for smartphones did not consider, i wanted a finished device. I bought to search for poorly insulated places in a wooden house, check electrical panels and electronic boards. In my copy version of 2.1.5. Cat photo copied from thermal imager to computer via cable.
This thermal camera is very simple to use but no temperature analysis feature due to photo capture only keeps JPG format not in radiometric format. Anyway there is great rainbow color spectrum that shows nice color differentiation and a custom entry of emmisivity is possible to provide more accurate temperatures.
