I saw this, and was intrigued so am taping the rest.
Following what I've seen, I've re-evaluated what I do for security in my home. I've fitted some extra locks/bolts, and am using them.
They're useful programmes to see just how useful so many 'everyday' things are to help them get inside the house. For instance...
Net curtain wires with hooks on the end - reach in, grab one from the window, and then use it to hook the keys out of the door. Done in just a few seconds, and no loud noises to alert any neighbours (though, it seems, neighbours are useless at spotting burglars). Simple steps to avoid that being used - fit the eyes on the curtain wires, not the hooks, and of course, don't leave the keys in the door, and leaving even the smallest window open is an invitation.
Oh, and burglars don't like venetian blinds - they rattle loudly, get in the way, and generally tangle the burglar up.
Been a real eye opener to just how fast they work, too. The 'just pop down the shops for half an hour, won't bother shutting all the windows' is plenty of time for them to get in, get the stuff, get out.
