Frequently asked questions

What's the difference between a traditional alarm system and a smart security system?

Traditional alarm systems are designed to detect break-ins and sound an alarm. Alarm.com takes security further by connecting sensors, video, automation, and professional monitoring into one intelligent system. That means your home can help detect potential threats, trigger automated responses, and keep you informed wherever you are.

Do I still need a security system if I already have security cameras?

Cameras help you see what's happening, but a security system helps protect your home by detecting threats, triggering alarms, and supporting emergency response. With Alarm.com, cameras, sensors, automation, and professional monitoring work together to provide a more complete layer of protection than any one device can provide alone.

Can I start with a basic security system and add more later?

What happens if the power or internet goes out?

How do I know what security devices I actually need?

Every home has different layouts, routines, and security priorities. That's why Alarm.com partners with trusted security professionals who can recommend the right combination of panels, sensors, cameras, and other connected devices to fit your home, so you only pay for the equipment you need.

Is a professionally installed security system worth it?

Professional installation helps make sure your system is designed for your home, installed correctly, and configured to work together from day one. Your security professional can also recommend the right devices, optimize sensor placement, and help you get the most from your Alarm.com system.
