content: The Mileseey TR256i is just one of many mobile phone dongle format cameras that use the Infiray Tiny series of cores. They use the Infiray core because of its good performance and relatively low cost to the OEM. Mileseey is a decent manufacturer and it is no surprise that the TR256i performs well. Things to be aware of are the fact that it is a fixed focus camera so close-up work on a PCB will require the addition of an inexpensive $20 ZnSe ZnSe lens, as used with many other thermal cameras for close-up work, and the camera will require the use of the Mileseey phone APP. Whilst it may work with other OEM’s APPs and those from 3rd parties, this is not guaranteed as some OEMs lock their cameras to work with only their own APPHaving read the user manual and specifications for the TR256i I was pleased to see that the APP contains features that will be very useful to you. You can set ROI’s, Max/Min temperature tracking and it has a manual scene level and span option. I saw nothing that would discourage me from buying this particular dongle camera, if a dongle camera is what you prefer to buy. I personally still prefer the ‘all in one’ pistol grip format of camera, but that is my personal preference. With the dongle format camera you can use a USB extension lead to create a PCB inspection station with a simple desk stand or just make ten camera more versatile by using it on the end of an umbilical, rather than attached to the phone. I cannot say whether the TR256i will work with available PC software so it is likely best to work on the basis that it will only work with a mobile phone that is running the Mileseey provided APP.If you are seeing a good deal on this TR256i camera, I see no reason to not buy it. Please ignore minor differences in thermal sensitivity specifications as that can often be “marketing department tactics”.Mileseey page for TR256i (currently offering discounts)https://mileseeytools.com/products/thermal-imaging-camera-for-phone-mileseey-tr256i?User Manual ……https://cdn-files.myshopline.com/file/store/1709871255948/TR256i-User-Manual-2.pdfYou may want to compare the Mileseey TR256i with the offerings from TOPDON as they have decent thermal cameras at good prices. Just avoid the bottom end cameras that use a 96x96 or 160x120 pixel microbolometer. It may also be best to avoid the TOPDON dongle camera that has a visible light camera as some users report temperature gradient on the displayed image.Fraser
