Currently my boat has 5 cameras my IRIS junction box and selector pad has 8 spots. I have one that faces the stern, but when the Dingy is up on the top deck/fly bridge you cannot see the stern of the boat with the camera. I know cameras have come a long way and have gotten a lot cheaper My Iris system has 3 available slots to add cameras so I am thinking of adding a couple more. I was thinking of adding a FLIR camera to one of the open “terminals” at a later time. At this time I am thinking of adding a Stern/cockpit camera to aid me in back the boat into a slip. — I use this feature on my trucks all the time to hook up to trailers/ get feed for my animals etc, so I am pretty used to having it there and using what I see to operate equipment. Does/Has anyone else do/done this? Does anyone know if I can only use an IRIS camera or will other brands work?
