Adding microphone / audio to security camera

Hello all. I have an Amcrest camera on the roof. It does not have audio. I'd like to add a microphone near the camera and run it 55 feet back to my computer. Any ideas? 3.5 cable? What about the long run? Wouldn't I have to have a powered mic or some kind of a preamp? Comments appreciated.
