I have taken a closer look at the first camera (with case) and all look very good.http://www.aliexpress.com/item/Guaratee ... 40080.html
It has a ½ inch CMOS sensor with a rolling shutter. A global shutter would be better, but it's OK for this price!
A high resolution 3M pixels sensor.
A built-in IR cut-off filter.
Connection for C and CS mount lenses.
5 different resolutions.
Drivers for the current Windows versions.
I would say: It should work for DAVID. But who knows how fine?
So take heart and give it a try.
