I had to bring my BeeCam inside to replace the lens and change the lens mount, because it is definitely _not_ waterproof!
It's sitting in a bag of rice right now, which is actually doing a pretty decent job. It'll have water spots, but it'll be dry.
I have another camera/lens assembly, so I put that in behind a standard 35 mm UV filter with silicone:
I still haven't figured out the public streaming bit, but I used ffmpeg to save a 60 second video:
It's working well, but yes, that regulator gets hot as hell.
While I had it inside I only had about 3' of Cat5e between the 12V supply and the regulator assembly, so it was dumping 7W. I had put the regulator board into a prototyping box, and it was too hot for me to touch. It even shut down a few times. It didn't do that during nearly a week when it was out in the field, over 100' of cable, so the 2V/1W reduction over the cable must have been just enough to prevent it shutting down. So I must be right on the margin.
My ezsbc linear regulators should arrive any day, so assuming I don't blow them up (again) I should have fixed the heat problem.
I also replaced MotionEye with RaspberryIPCamera
because it outputs h.264 over RTSP, which reduces the network traffic by about 90%. But that might increase the power consumption, because it's doing GPU compression/encoding. I forgot to measure the current before I put it back out in the field.
