A few simple security measures can prevent most burglaries and home intrusion attempts. Research indicates that most residential thefts result from the burglar compromising the front door lock. Residential anti-burglary door guards are a key part in defending against this approach. They increase the time needed for a perpetrator to break in. This increases the chance that they will be seen (and identified or interrupted),. Even frustrating them into moving onto a less attractive target is a useful tactic when protecting your home.
