I'd like to add the Infrared Interior Camera to the 129 Duo installation and not lose the rear camera. Anyone know of an "A/B switch" that can used to toggle between the rear camera and the infrared interior camera?
I'm no expert but would guess it's not possible. I think you would need firmware that could run both types of rear camera. If it were possible, I guess you would need a 10 pin USB switchable rear camera cable splitter. Something like a short rear camera cable to a switchable 'Y' connector, then the two rear camera cables out.
