Aside from NVR compatibility, when I did my research I found the low-light camera to beat is still the Dahua IPC-HDW5231R-ZE 2MP Starlight. Outdoor usage: Check. Good low-light performance: Check. PoE: Check. $100-$200 USD: Check. It's manual pan/tilt. It has motorized zoom.
I'll be using mine with Synology NAS Surveillance Station software... maybe. (Their notification mechanism is currently thoroughly broken. If they don't get it fixed, I'll have to find another solution.)
N.B.: I have not installed this camera yet. It's wintertime, here, and I don't feel like hacking on our vinyl soffits and crawling through the attic in sub-freezing temperatures, or tracking snow, slush and mud all over creation.
