Thanks, it's this one: https://bolyinc.com/product/2060-t/ Also available on Amazon and maybe other places.
I haven't tried the photo option or the black IR.
I wish I'd left the cam I had up that was on top aiming down the length of the bridge. I may put one back up...maybe it'll be a habit of his. Or most likely for the rest of my life I'll never see that again.
