Insure your valuables
There’s quite a lot to unpack in this person’s post. First, the OP advises that we should make our homes as unattractive to burglars as possible. This means using lights and having security cameras installed. However, we prepare ourselves for the worst-case scenario, i.e., assume that the bad guy has broken into our homes.
First, keep valuables offsite in a bank or other institution that can guarantee maximum protection. Second, bolt things down into concrete if at all possible. Burglars will have to use loud tools to get at them. Finally, get insurance for stuff you can’t afford to lose, like jewelry and expensive electronics.
