Video-In
S-Video or composite, always - standard, otherwise they are equivalent and easily converted into one another.

The information that the camera can be connected also goes in favor.

I assume that the appropriate cable should go with the device or can be ordered from the manufacturer (and costs relatively expensive ).
Well I also guess you want to make it (there are some to buy on the market, cheap).

Pay attention - are you sure it's 3.5mm? It is audio standard. Maybe it is 3mm, or less, maybe very similar.
If so, you can use something like [Only registered and activated users can see links. ]. or [Only registered and activated users can see links. ]
