I recently purchased this camera:

I plan to hook it up to my Pioneer AVIC N2 as a rear view camera. I see on the website that it runs on 9 volts rather than the 12 that a car has. What resistor or other device do I need to reduce the current to 9 volts? Thanks in advance.

I would not use a resistor. Even if you knew the current draw, the voltage in the vehicle changes and so will the voltage applied to the camera. I'm gonna assume that the camera draws less than 1-1/2 amps. In that case I would use a simple 9-volt regulator transistor

Google "Voltage Regulator 7809"

Simple connections, 12-volts in, ground and 9-volts out. Its that simple

so what would happen to this camera if I hooked it up to 12V in my car?
