Best Wireless Home Security System

Vivint wireless alarm systems use smart home technology like Z-Wave to connect devices—such as sensors, wireless security cameras, and locks—to a central hub. The hub communicates with Vivint’s monitoring centers using both internet and cellular connections.

This setup keeps your wireless security system responsive and reliable, while giving you real-time alerts and control from the Vivint app.

Wireless alarm systems can use different communication methods, including internet and cellular connections. Vivint systems use your home’s internet as the primary connection, with a built-in cellular backup to keep your system online if the internet goes down. Even during outages, your system stays connected and continues to protect your home.

Wireless sensors use secure radio signals to communicate with your system’s hub. When a sensor is triggered—like a door opening or motion detected—it sends a signal to the hub, which can trigger alerts, recordings, or alarms. Zigbee and Z-Wave are wireless protocols that help smart home devices communicate.

This communication happens instantly, so you’re always informed about what’s happening at home.

Vivint offers a full range of wireless products designed to work together in one system. This includes the Door & Window Sensors, Motion Sensor, Glass Break Detector, Smart Lock, Keypad, and key fob.
