The reversing cameras below all use the 4 pin waterproof connector, sometimes referred to as 4 pin aviation connector. This has been around for over a decade now and is one of the most reliable waterproof connectors available. Every manufacturer that we have seen has pinned these out the same way, except one (but they have the male/female on the opposite sides so it is impossible to plug ours in and cause issues).
