Yeah. One really important one. HEAT! Attics can easily reach temps of 110 plus degrees (unless you're in Alaska or Antarctica). I would avoid attic placement at all costs. You'll end up having to replace your recorder at some point.

KTNC makes a nice user friendly NVR with either 4/8/16 inputs. The 8 port unit actually supports 16 cameras with the use of an external POE switch. It's easy to use and set up. If you're not a KTNC dealer, you'll have to purchase retail online.

Ever consider a guard dog service?

Hikvision manufacturers a lot of OEM cameras for other vendors. Their equipment is good stuff. You said your budget is around 8K. Does that take into consideration how you are going to get the signals back from the camera to the monitor/recorder? Are you planning on PoE cameras? Are you running conduit for all the cabling? If I were designing this system, I would go with IP/PoE cameras and using Ubiquiti Nano 5.8gHz units to get the video from the camera to the recorder. You could use 8 port PoE switches for each Nano. The Nano's are relatively inexpensive, so you could have them strategically placed around the property, cutting down on conduit runs. I would avoid consumer grade (Costco/Sam's Club) cameras as they just won't hold up as well as other beefier units.

I came into this thread a bit late, but, can offer some info. I know of no camera that is "fiber ready". But, fiber media converter that convert IP to fiber and back again are inexpensive and will solve the problem. You would need to provide power to the media converter, but it doesn't really have to be at the camera. You could consolidate all the IP in one cabinet and install the media converters there.
