The image quality is very average, the picture is quite noisy even when the brightness is rather important, 5 Mpix or even lowering the resolution. I do not know if this is the image capture software, or if it is equipment that is so, I have not yet taken the time to investigate further.
In terms of reactivity, it is pretty average but also a Raspberry Pi, this is not very fast ...
The connector is not the most practical but it avoids to occupy a USB port.
