Are you thinking about adding a security system to your Pasadena, CA home? You aren’t alone. 34 percent of U.S. households—or approximately 36 million homes—currently own a home security system, according to Parks Associates. And that number is predicted only to keep growing. 

But if you’re worried about trespassers on your property, you’ll need more than a few security cameras. With a complete access control system, visitors will be stopped at your gate or front door and prompted to enter a code. Motion sensors will notify you that someone’s there so that you can speak to them through the two-way intercom. If they aren’t welcome, you can call the necessary authorities. 

However, a DIY access control setup can only take you so far. With a professional smart security system installation, all your security devices work together to achieve one common goal: safety. Here’s what a professionally installed system can achieve that a single smart device can’t do alone.
