To properly secure your home from external threats, you must find weaknesses potential entry points and fix them.
Step 1: Secure your doors Install solid core doors and secure them with heavy-duty locks. Fasten heavy-duty lock strike plates to the doorframes with 3-inch screws. Install deadbolt locks across from each door hinge.
Step 2: Install window locks Install window pin locks to limit the distance the windows can open.
Step 3: Install protective window film Place protective film on the windows to help prevent the glass from shattering should anyone try to break the window. Fit your windows with burglar alarms.
TIP: Attach motion detectors to lights and appliances inside the house.
Step 4: Install a peephole Install a peephole, preferably one with wide-angle vision, in your front door. Get in the habit of looking through it before opening the door, and keep your porch light on at night.
FACT: The 1979 movie When a Stranger Calls, features the famous line, "We've traced the call. It's coming from inside the house!"
