Burglars Hate Inconvenience
Thieves want quick and easy jobs. They want to gain access to a house and grab your valuables fast before running away.
Or at least that’s what they will be hoping for. Typical anti-theft devices are something many burglars are familiar with already, so don’t bother trying to fool them that way.
The best thing to do is to make everything as time-consuming and inconvenient as you can. This puts a dent in their thieving attempts, since they know they won’t be in and out as fast as they’d like.
The longer it takes them to find or access things to steal, the more likely they are just to quit and try somewhere else.
