"Young redditors may not have heard of this thing; it's called 'radio'. Leave a talk station on when you're out. No burglar's gonna come in if he hears voices, unless it's a home invasion. Leave a light on, doesn't matter if you put a timer on it or not. Just a low level light, like it's a night light for going to the bathroom in the middle of the night. A dog is another big plus. Hard for anyone to get past a dog in the dark. They don't need to see you to bark and bite you. Have never been burglarized, ever, and I'm 67 years old. That is all."

"If you're moving into a newly built complex, CHANGE THE LOCKS. Just over a year ago, my housemate and his girlfriend came back to our place to find that laptops and jewellry had been nicked, and there was no sign of forced entry - also we live in South Africa, so doors are always locked.

Turns out the builders were cheap, and used the same three types of locks for the front doors. Strongly suspect that ex-employees of the company did a short term rental of a unit (three months probably) and just took notes of everyone's comings and goings. Then just wander to a unit, try one of the three keys and then casually stroll out with a laptop bag stuffed with goodies. We weren't the only unit to be hit, and the HOA only sent out a notice to be vigilant after I spoke to the niece of one of the people who were on the board."
