Phaedrus... good luck with your endeavor... after watching the movie "No Country for Old Men", I'd wondered what it would take to shear a brass cylinder out of a lock...

I went with exterior steel doors, and longer screws to the striker plate and good dead bolts, but not a high end lockset... unfortunately my house is an old frame structure , and though off the ground on 2' pilings it has a couple of 7' jalousie windows that would be easily defeated

the front, and rear entrances are accessed by easy open screen doors, but I installed a wireless "chime" with the speaker in the bedroom that sounds when they are opened...that and a couple of motion sensor lights...

I don't have a large perception of threat,... I'm just a kindly old retired school teacher, and no "ostentatious display of wealth"... my nightstand pistol is a lowly G23 with night sights
