Neat that you’re looking to use it in an ROV! I’m actually planning on building a rig to use mine as an underwater camera at some point - not on an ROV but just one that hangs by a wire for scoping out fishing grounds. My plan is to pick up a dive case and then 3D print (and sand and seal) an enclosure that will replace the end cap of the housing. I’m planning on using USB as wifi underwater can be tricky! Going to either use a Pi4 or a Jetson underwater (with additional sensors for direction, depth, water temp, and possibly in the future dissolved oxygen content), then ethernet over powerline to the surface (so the tether can provide both data and 12v over a pair of wires), with another Pi4 or Jetson (or just a laptop to start) to record, decode and display the signal topside. Hoping for under 1s end to end latency, but we’ll see.
Do you know that wifi will work for your planned use? Might be worth considering usb; it means that you can’t just use the straight dive housing, but guarantees a reliable connection and also lets you power the camera externally…
