You might not have a criminal mind, but think how a crook finds the perfect houses to target. An empty home in a neighborhood where people keep to themselves, no cameras or alarms, and dark or dimly lit structures, right?
Tap or click to order your home security system from our sponsor, SimpliSafe.
A home security system can go a long way toward making your house unattractive to thieves, but there are more steps you can take to deter burglars. Here are nine tips you can implement right away.
1. Know your neighbors
Your house (and neighbors’ homes) will be less attractive to burglars if the people on your street spend time on their porches, working in their yards or socializing outdoors. Neighbors who know each other look out for each other.
Make friends with the people on your street. If you trust them, you can ask them to help keep an eye on your house when you’re on vacation.
You can check if there’s a Neighborhood Watch program for your area. And if there isn’t, maybe you should be the one to start it. Tap or click here for the 10 questions you should ask if you want a home security system.
2. Install video cameras
A study by the Alarm Industry Research and Educational Foundation found more than 60% of burglars would consider the presence of cameras or surveillance equipment when choosing a target. This is where a home security system comes in.
