Not sure this would work with every camera. My particular model does not support remote shooting over USB. Newer models of the same camera do and Sony even provides software to go the USB route.
The native Sony software will only support 720p resolution. So gphoto2 still offers better resolution.
"Shooting over USB" is not a requirement to use this. The camera only needs to be able to output the preview stream via USB, which works with most cameras.
