A good place to start is /r/homedefense. There are some excellent "off-grid" security systems there. Check the sidebar.
I plan on getting a cheap Honeywell Lynx head unit and a bunch of sensors for under $200. And then interfacing a RaspPi to that for alerts/web ui.
On the video side, the newer Foscam 720p cameras are excellent with an SD slot for local DVR as well and the ability to stream/push/pull video for off-site storage.
