I can certainly understand keeping it more simple than over complicating it. I know for me with my drip system if the power cuts out I'll have 30 or 40 gallons flow out the drain, I plan on just letting the drip refill it as well once the power turns back on.I may go a similar route but want to try the analog approach first. There is a modified ATO approach already going into the sump. The way I designed the system it should work without having to use solenoids or pumps as the drip fills the tank back up. The sump goes offline one evening per week after a backwash. I can turn it back on once the tank is full. You know how it goes. I'll likely go the automated route when I run out of things to build and over complicate.
With mine being below the surface I am really hoping to find something with all three of the features, PTZ. With a narrow focus I won't be able to see most of it so PTZ is pretty important. I did look at that camera on BRS, it has some mixed reviews and not a great image. Plus the lack of movement rules it out for me. Thanks for the suggestion though!I like that one a lot. I really want the zoom portion though. More so than the pan and tilt options. That makes sense how you describe yours. I saw bulk reef supply also has under water cameras by design,. Take a peek and see if that might work better for you?

Hopefully that changes for you! Yours are a lot bigger than mine. Mine are only 11"ish, so maybe I have longer than I thought. Mine are supposed to be about 2 years old.I am hoping for the same. I only have one pair but the female has not been very receptive. They get another crack at it the first week of May. The male is mature and has tagged a couple other females. They are roughly 16"-18".
