Try to trigger video using GPIO on your desk in order to narrow the issue. It is easy to do: connect camera and use wire with 3.3V to configured input pin. Would be useful to check it on few pins.
It is hard to asses your diagram as there missing pin numbers. What is the expected input current? What is the voltage level on the Rpi input?
What is the state on Collector if there is no signal from reverse lamp?
