The police are useless for property crimes in Britain.
That’s why smart homeowners invest in much more advanced physical security of their homes, instead of alarms.
I copied a lot of these, given the constant flow of illegal immigrants in west Texas Smash proof doors and door frames, most external doors are commercial that open “out” with protected hinges, high security deadbolts that can’t be bumped, windows with lucite layer in the middle that can’t be smashed, window frames that are actually bars, various kinds of bars that don’t look like bars — metal plant trellises in front of windows with climbing roses, safe room, etc. Commercial garage doors that are much lower gauge steel and can’t be easily sprung. Plus wired cameras and alarms, not that they help anymore.
Real, built in, safes for things.
All in a gated community with a guard, who would stop casual theives.
And, of course, appropriate weaponry and training.
Climbing roses are good to put in front of windows, but pyracantha is even better IMO. Tough stems and really nasty thorns. Roses look better, though.
