I downloaded the intuition software from huehd.com/new , as no cd/dvd drive on pc. When installed it wanted to use C drive but I have M2 drive with little space (or rather I don't want to clutter it) so changed it to install on my D drive. This gave no issues.
Running the software I found the video would not save and the program crashed. After restarting program I went into setting and set paths in drive D & created a 'Hue folder with subfiles, photo, temp video and video - I think it was trying to save to C and could not find a folder (since there was not one).
I did get a crash again, but on the next restart of the program it all seemed to work.
After recording a video it goes to playback where you can see it, then you have to save it to your chosen file path - saves as WMV file - cant see option for other formats. Quality is ok - is only 720 res and the lens in the camera is very basic - (see the video review with this).
I found adjusting the focus easy in terms of the physical side of things, but quite hard to get a perfect focus on a document - centre seemed good but getting edge blur.
Seems okay for a webcam as more distant focus is more acceptable.
If you were going to use it as a visualiser for online lessons then it will be a fiddle making sure it is close enough for text to be legible. No auto focus or program zoom means moving the camera back and forth.
I'm sure that it would suffice.
The software allows photos, but I cannot see a lot of difference between scan, document capture and Image capture - there are not a lot of settings you can adjust! I took the same photo on each and could not see a difference, except that i could write on the document camera one with a very basic tool - but it does work - see photo.
Turning the led on and off is easy, but I could not really see a difference. In my bright room, the lighting is almost too bright for the camera.
In summary it is not a bad camera for this price and this is coupled with the fact that it is hard to find any camera that you can actually buy and get delivered during lock down.
