home security systems

Is there a home security system that you can recommend for the home tinkerer?

I'd like a system that offers a few key features:

• outdoor video cameras that also work at night (infrared) and in cold (-34C/-30F temperatures)
• cameras available in either wired ethernet or wireless
• hub can store video to local network disk (not just to a paid cloud service)
• includes a doorbell/camera device
• support Linux and Android for easy access
• wired power rather than batteries (don't sacrifice the environment for some temporary peace of mind)

I like the mainstream availability of Insteon devices, but they're short on several of the features that I'd like. I don't want to have to cobble together a frankenstein collection of technologies. Those individual technologies are available though.

SkyBell
SmartCam
Ring
DoorBird
iDor
Lockitron
Korner (window sensors)
CleverLoop hub

ADT also send me a letter to reactivate the (old) system already in the house, but I'd rather have newer technology.  Still, though, I'm not ruling out a paid service provider like ADT.

I'd rather just buy a hub outright, provide hard drive storage of my own, then slowly add devices to the house over time.  Any suggestions?

I just learned about this earlier article covering OpenCV and the Raspberry Pi.
