This is a really cool idea, I’m pretty psyched to see if it’ll work. I think Nima’s right with the EA E-30CL, though I think an issue you may run into is heat generated by the chip on the back of the unit, which is (I believe - EE nerds please correct me if I’m wrong) doing the video compression.
If you’re going to pot the whole assembly, I think it might be worth it to put some metal pieces in the potting that are exposed to water, for cooling. Something like this:
Where the metal is close to or touching the chip surface.
Either way, (and I apologize if this is something you already know) epoxy has a hard time sticking to polypro, so that’s a good candidate for making your mold, if you just want a camera in a block of epoxy. Also, potting an assembly this large without some good heat transfer (like the metal fins) could result in bricking your camera, because epoxy releases heat as it cures, and cures faster at higher temperatures, so big blocks get super hot in the middle as they go.
Can’t wait to see the result when you try this!
