Cut off the plug and expose the wires.
Connect a 12V DC power supply to the red (positive) and black (ground/negative wires). NB: I suspect that the camera will require quite a large current, so make sure that you use a suitable power source. A little 'universal' power adapter (of the type used to power portable CD players and similar devices) almost certainly wouldn't be up to the job.
Separate the grey coax into the central (pink) cable and its screen. Connect those to an RCA connector (= 'phono plug'), with pink going to the pin and the screen going to the outer connector. You should ideally use a yellow connector for composite video but, as long as you know which connector is which, it doesn't really matter.
The camera doesn't have stereo sound but you can use the brown and white mini coax cables to connect to the left and right channels of an RCA input (or split one of them to serve both inputs).
Of course if your modern device hasn't got an RCA input you'll need to use a different connector (and modify these instructions accordingly) but the basic principles remain the same.
