Always on reverse camera - pedroc1999 - 09-13-2021

Is there any downside to have a reverse camera that is always powered (off of ignition)?

By this, I mean will OAP have a memory leak or something of the sorts? I will be using a USB video grabber, and intend on not wiring a GPIO trigger pin, and instead just manually clicking the reverse camera button whenever required.

OPA will not leak memory Smile However this could happen with grabber driver. On the other hand you have to consider battery drain.

Good to know!

Battery drain is a non issue as my large buck converter only has power when the ignition is on

By the way, what is the most efficient way to use the car reverse camera system for OPA? Need a USB video grabber? any alternative or better solution?

AFAIK the official solution is to use a Pi camera.

The Pi Camera ribbon cable is too short for car and, also, the camera doesn't fit into the original backup camera location. I really wonder if there is a better alternative.

There are several alternative solutions with adapters or video grabbers. You can find them at forum.

I agree, that's why I've used a usb grabber and a specific for my car RCA backup camera.

(for the pi camera, people use camera-cable-hdmi-camera-able adapters)

Check out what user gecko242 did, he used the official Pi camera and an extension cable.
