 Brian, protecting the cable from what?  It connects to penetrators at each end with shrink tube, and then potted.Hank

 Hank,     How are you protecting the cable?

 Brian, since my sub has no hatch window, I can not see when I am submerged.  Also I can not see above the waterline once I am surfaced.  To solve this I installed a automotive back-up camera.  I used the type that has a cable, not the wireless.  I put the camera in a housing and used the cable it comes with.  The come with plenty of cable if you buy one for a bus.  They are cheap and the picture is good enough for the purpose.  They also have LED lights built in.Hank

 Hi Ian,                 I was thinking the later with an Ethernet cable and a computer.  Since I'm such a long way from the bow of my boat I figure it might be a good idea to put a camera out there.  I have my 10' x 28" dia cylinder which intersects my 5' diameter sphere where my batteries and electrical components for the motors reside, I think I'm going to put a 16" x 14.5" monitor at about 5' into the cylinder where the batteries start so I can still get to all the electronics, and then have a small form factor computer running for the cameras and navigation.  Since the monitor and the computer would be relatively low power consumption I was going to run a dedicated inverter for those.   I have plenty of ports available to run data cables thru , just not sure what to use, would that be a subcon item?

Hi Brian,
what type of 'technology' are you thinking of putting in your sub?
You could do a composite video type camera with a rather simple display in the sub, or you do somethingwhich was using Ethernet, and have a computer inside (laptop or built in computer) to connect to the camera anddisplay/record the camera image.  There is USB as well, but I feel that is not the right data bus for a sub, and if I'mgoing to have a computer and wiring I might as well standardize on Ethernet and enjoy the flexibility.
There is also Power over Ethernet (PoE) which is popular with some hi-res (4K) security camera, this couldgive you power and comms/data in one cable.  Just need to build a pressure proof housing for the camera.PoE would require a Cat5e or Cat6 type cable.
I'm still mulling all this over myself, so interested to see that others think.
Cheers,  Ian.

Hi All,               I'm thinking about having at least one camera on the outside of my sub.   I assume they probably need a Cat 5 cable,  does anyone know a recommended undersea cable for that?  Also could want to have it move.
