When the cops were checking things out they asked about the dog... where was she at the time? In the air conditioning in our bedroom, where else!
I had to laugh. Years ago when hubby and I were both poor students living in a very run down cottage in a less than salubrious part of town we had a car broken into. It was parked right outside our bedroom window and we never heard a thing. Like us our dog was asleep in the room with us enjoying the air conditioning. Talk about brazen...after stealing the car stereo the first time around they thieves came back a few nights later and ripped out the speakers. We heard them this time but they ran off with their loot before we could get out the door to stop them.
Gooram, I strongly recommend an alarm system. Our current PPOR had a monitored alarm already installed when we purchased it because the previous owners had their own business and often had large amounts of cash on the premises as well as plenty of money for desirable items. After getting broken into a few times they had the alarm installed and a small safe and never had another problem. We've been here 5.5 years without a problem also except for someone recently stealing our garden trailer from out the front (it was a wreck - we didn't think anyone would want it ). Previous owners and us have never considered security screens as a real feature of the house is lots of floor to ceiling windows which would be spoilt. The other thing we have is motion sensor lights right around the house and only access to backyard through garage or a high locked side gate. Another thing to consider is to keep windows clear of vegetation and anything else that might shield a thief from view whilst they try to gain access. When we're away on holidays we rig up lamps to timers so that the house is lit at night. For $10 or so you can get these timers from Bunnings that come on and off at random times within in certain timeframe (say 6pm-midnight) so it would really confuse anyone who might be casing the place. Off course, you need to get your mail collected daily or held by the post office as this is a dead giveaway.
BTW, with a monitored alarm most insurers offer a good discount on your policy. We only have ours monitored when we are away on holidays, rest of the time the alarm rings our mobile phones if it is activated or the power is cut. Whichever way you go the alarm is sure to be a deterent. Most thieves will move on to an easier target.
