The new camera has arrived. I won't be able to install it immediately, but I thought folks might like to see a few pictures that may help explain how it's installed.
First, here's a picture of the camera which comes with about a 4-1/2 foot cable hardwired:
The cable has two pieces already attached. The first is a small bump, probably a ballast to improve the signal:
The second is a grommet:
Finally, here's a picture of the mounting bracket:
As far as I can see, the hole in the center of the mounting bracket is large enough for the cable and ballast to fit through, but not large enough for the grommet. So...I think the standard mounting for this is to drill a hole in the RV fiberglass large enough for the grommet to fit in. Then attach the camera's cable to a longer cable inside the back cap, push everything into the hole and seal it with the grommet. Then screw the mounting bracket to the fiberglass and mount the camera on the bracket.
I guess I'll find out if I'm right when I get the chance to take things apart and try the installation. I've got a couple of worries - maybe FR gets their cameras with a single long cable, so there's no connection in the back cap or maybe there is a connection, but there isn't enough slack in the cable to pull it out of the hole to remove the old camera and attach the new one. Time will tell (unless someone else already knows...)
