I assume your ZS10 is a Panasonic.
And it sounds as if you are wanting a web-cam.
To do what you want, the camera would need a driver and special firmware.
Very few cameras use drivers any more.
The Panasonic ZS10 does not.
It will not work as you described.
....
I need to connect the AV out to a down-link wireless .
I want to make sure that doing so will give me a view of what the camera see's in real time ?
also, will it work in stills and video mode the same?
