Moving to a new place and need to install security, and was hoping to get some recommendations on what's a good, reliable system that won't lock me down to a single monitoring service.

Prewiring for that in the home is very minimal. There seems to be a few cables strung for keypads near doors, but nothing else (well, another cable for a motion sensor, but I literally can't see any others). Would still prefer to go wired versus wireless despite the difficulty that entails.
