Hi everyone. Recently moved house so it's just me and the better half. Ground floor flat, seemingly decent enough area, however after our first night, police knocked at the door asking us if we had heard anything from a break in across the back garden. (2 sets of flats share the same back garden space) Now I remember the guy having a guitar in his back window and thinking "haha, lucky that's not in your front window mate or that'll be gone in a heartbeat!" Bare in mind this is a back window, so these guys must have hopped the 8ft fence or came through one of the closes. It could have been an opportunistic thief, a person they knew, or someone who had been staking the place out. Whichever way it went down, I'm not gonna find out! What is the most effective preventative measures I can take to deter anyone from even trying to smash a window as well as breaking and entering in general?The house has an alarm but I have a cat. Who likes to jump EVERYWHERE so even covering the sensors at the bottom doesn't seem to make a difference! I thought about getting some sort of sensor to go on the windows that go off if anyone breaks the glass or tampers with them. Just not sure what to go with there, alarms aren't my speciality. I don't think anyone is going to come in the front door, besides it's got 3 locks so I'm not worried about that. I'm also thinking about IP cams to alert to motion but I don't have the money for them at the moment. Other than this, I'm actually most worried about personal data being stolen. What's the best way to prepare for this? I've got passwords on my systems but nothing deeper than that. No encryption. I've got a few TB of data on my big computer which is probably a bit big and heavy for anyone to stroll down the street with but you never know! the laptops etc. however are easily lifted. In the long term I want to put most of our data in the cupboard (maybe somehow screwing it in place?) in the bedroom and pop a lock on that for another layer of physical security.
