Reece - so sorry to hear this - living in Cape Town South Africa for much of the year, one gets very hyper about security - my house has high walls, very powerful electric fence, beams to trigger alarm then security alarms each window and door, plastic bars on each opening window, anti smash film on all non opening windows, cameras etc oh and guaranteed 2 minute armed response which I think is the biggest deterrent of all - and these guys don't muck around, so can and do shoot if necessary. Even though crime is high, never had an issue personally, so I do think these days one does need to take whatever precautions one can to protect yourself and your possessions
Hope they catch the thieves and you get all you stuff back
