need an inexpensive " reverse Image " bullet camera for VX2

[Offshore]

I need an inexpensive " reverse image " bullet camera for my VX2 plotter.
My old camera went bad. Raymarine replacement is ridiculously expensive.
All cables are there, just need a camera suggestion.

Vx2 with optional video input displays 640x480 composite video. It would need to be something that supports RCA composite and 640x480. In today's world that might be much harder to find than in the older days.
