4. Install sensor lights at appropriate positions around the house.[/quote]
Regarding 3, just make sure your team understands that the locks have be re-installed before they leave. It's seriously your arse on the line, so be strict with those that forget to lock up. I don't want to appear as a scare-monger, but you could seriously lose your house. Where I live, you can be sued if someone slips on the icy sidewalk in front of your house. Bags of salt and salty sand are big sellers this time of year.
Regarding 4, make sure the lights are high enough that they can't be unscrewed or install tamper-proof models. My garage was broken into last June and they unscrewed the lbulbs on the light next to the door. The next day I installed a security light high up on the front of the garage - way out of reach.
And I recommend a dog. When my wife and I get an acreage (one day), I'm getting a
Neopolitan Mastiff. Quite possibly the ugliest animal alive, but they're good with their owners and really mean to strangers.
