I've fitted quite a few camera kits to bikes, several being made by innovv, I'm yet to fit a set to a Vstrom however.
Fitting the cameras in a discreet place, front and back where they can't be damaged easily or tampered with in my opinion is best.
Fit the controller on clutch lever side and the hard drive/card slot securely under the seat so it can't get wet or dirty.
Hiding all the wires can be a pain but it's easier with panels/tank off so the wires can be secured and hidden properly.
