Thanks for the suggestions!
The Skype thing is a great idea. We'll employ that for the sump.
The camera set up lengthways down the glass appears to be the way to go to beat glare. I'm not able to see the sump when I do that, though.
The bonus is that I can pan it to see the front door from that location, and then call up my #1 son and give him heck when he neglects to lock it. He's been mumbling something about "1984."
I'm able to see the waterlevel in the display, and determine how clear the water is. I'm also able to see a lot of the activity, and whether or not corals are open. With the "night" feature, I'm able to make out everything I can when the lights are on . . . It's just darker.
The biggest source of glare actually seems to be the T5s, so the camera needs to be close enought to the tank that they don't come into view.
