A:Answer Yes, you need an adapter for it. BNC to BNC adapter. It can only go so far, so don't try connecting more than 2. You can also buy a BNC cable that will be that long too. if you are going to the hassle of setting up cameras, you might as well utilize the 4 it comes with and get a longer cable to run for the one. You are going to have to buy that adapter anyways. Plus I am sure you can think of another place for that camera.
