Uni-T has released software for the UTi165K thermal scanner with video out. It's very simple but works for most use cases.
Download it by clicking this button:
Un-zip and run the installer to get the desktop icon for the app
By default the language the fever scanner comes in Chinese. If you read Chinese, great! If not...here's how to change it to English
Unplug the scanner from USB before starting the app. Then open the app and look for the menu in the top left, select the GEAR ICON (third icon)
This dialog will open up
From the drop down, select English
Press the LEFT button
You'll get this notice (it says changes will take affect on next launch).
Quit the app and restart it. This time you can plug in the camera before you start.
Once connected, you'll get a video with a mirror of the display.
There's a few alarm options.
Allow sound means that the computer will beep (not the device, the computer speakers) when temperature goes above the upper set limit.
Log generation will take photos every time a high temperature event occurs
