Home Security Systems questions, answered by experts

If you want to make more home security upgrades to your perimeter, consider installing a smart automatic gate opener and a security camera. These will allow you to see who’s at the gate and open it for them (or not). You can learn how to install an automatic gate opener yourself or hire a professional for a little extra.

Instead of a security door, you might opt for a heavy-duty screen door made from durable mesh, which allows better sunlight and airflow. Additionally, you could enhance security by installing strong locks on your existing door. A double-cylinder deadbolt provides robust security; however, be aware that some local laws prohibit them due to safety concerns during emergencies.

A security camera company will be able to advise you on where to position the cameras, ensure all of the equipment is set up properly, and do all of the installations. They’ll take factors into consideration that a non-professional might not automatically consider, like obstacles that could block a potential trespasser from the camera or how lighting may obstruct the view.

Your best bet is to install a bracket that secures to the bottom of the unit and the side of your house. You should still secure the AC unit in the open window using some of the other methods already listed, but a bracket is best to ensure that it stays put—both during operation and in case of an attempted theft.
