content: Hi everyone,I'm interested on buy the HIKMICRO Mini2Plus V2, mostly for the resolution and the 10cm minimum focus distance for PCB inspection.Anyone who have tested it and can evaluate the image quality ?Best regards.

content: The image quality is quit good.I attached images of a ESP32-C3 Supermini, a LD2410C Radar module and a Raspberry Pi 3B.Due to the manual focus its possible to use the best distance to fit your area of interest.The device works with iOS (tested iOS 15 on iPhone 7 and 18 on iPhone 14 + iPad Pro) and Android (testet 14 on Samsung).Both Apps work OK, but have some minor bugs. The Android version seems to be a bit better than the iOS version.Compared to a Flir i3 (with patch to i7 - thanks to eevblog :-) the measured temperatures are a bit off.Especially colder areas (cold corners of the room) are shown around 3 degree to low, while warmer/hot ones are measured very similar +/- 1 degreeThe device heats a bit up when used.The device is a bit slippery and the adapters a bit wobbly to use.I think i will need some 3D printed mounting solution instead of putting it directly to the USB/Lightning port.Over all I'm quite happy with the device.

content: Thanks for reply joeA.In the meantime I've got the camera and in the posthttps://www.eevblog.com/forum/thermal-imaging/minimum-specification-of-a-thermal-camera-for-pcb-repairs-some-thoughtsI've uploaded some photo, also with additional lens.Best regards.

content: Hello, honestly I'm not very satified with mine. It has 4 K difference between the diagonal ends of an isothermal image. I contacted them, but got no clear answer. It is not yet clear to me whether this is a defect of mine or a common behavior. Other people complain about this problem, but ususally reporting 2 K between corners... not 4 K like mine. It is clearly something related to self-calibration. I'll try to insist to have it replaced by a new one, let's see what happens. The service person I contacted is very kind, but actually didn't solve, at least as far as now. I'll keep you updated. Francesco

content: Hi,after reading many posts here on the forum (advice, recommendations and reviews) and seeing several reviews on YT of similar products, I bought this IR Cam mainly for these reasons:1) Manual focus2) Minimum focus distance3) The narrow FOV4) Compatibility with Android, iOS and Windows5) Complete equipment (case, cable and adapters)6) Complete and graphically pleasing App7) Professional and free HIKMICRO Analyzer program for Windows8 ) Extensive documentation of the Apps and programs9) Firmware update from App10) Lower price than other renowned manufacturersIn my sample (calibrated hot and stable) the detected thermal gradient, of an isothermal surface, is 1.2 °K. Fortunately the area involved is limited to a narrow upper right band of the FOV.I attach a thermal screenshot of a ceramic tile.Due to a technical problem with the update "Windows 11 Update KB5050009 causes external USB camera to stop working" I was unable to test the IR Cam connected directly to the PC.There are some points that are limiting, but perhaps in the future software developments will remedy them:a) The thermal photo, if rotated by the App, taken by the smartphone at the same time as the visual one, is upside down if imported into the Analyzer program.This happens when, to align and center the visual photo with the thermal one, the extender cable is used and the upside down IR cam is brought closer to the smartphone one. The smartphone app will show it compliant with the visual one, while the Analyzer program will show the upside down thermal image.b) It is not possible to record the thermal video from the App at the same time as the visual one.c) It is not possible to zoom the visual photo to size it to the thermal one, so the two photos, given the different FOV, will be difficult to compare.d) It is not possible to import the thermal video exported from the App into Analyzer. In Analyzer the thermal video can be analyzed only if previously recorded with the program, therefore it requires the direct connection of the IR cam with the PC.e) Analyzer does not provide the possibility of using a visual Cam to simultaneously record thermal and visual photos. It does not even allow you to associate a visual photo with the analysis project.I thank the user Fraser and those who contributed admirably in the discussions and insights.Iron
