A dog from canine friends works wonders as a deterrent for the opportunist thieve, a while back all of the houses in our compound were burgled except ours...
As far as security goes nothing will happen from the airline side of things, years ago when still in company accommodation we discovered when returning from leave (in those days we could still get leave) that our house had been "occupied" whilst we were away. Bathrooms left dirty and soiled, kitchen in a mess etc, there were no signs of a break in, wrote to the appropriate people in the company, the email wasn't even acknowledged. Found out later that security in that compound had a master key of the doors to the villa, went to ACE and bought some new locks!
