What is a common feature in modern alarm systems that enhances user interaction?

Touchscreen control panels are increasingly common in modern alarm systems because they significantly enhance user interaction. These panels offer intuitive interfaces that resemble smartphones or tablets, making them user-friendly. The graphical display allows users to quickly navigate through different system settings, including arming and disarming the system, viewing camera feeds, and managing alerts with ease.

In contrast to traditional manual operation, which can be cumbersome and less engaging, touchscreen panels provide a more accessible and efficient way for users to manage their security systems. Battery backups are essential for maintaining functionality during power outages but do not directly improve user interaction. On-site support involves assistance provided to users directly and while it is important for maintenance and troubleshooting, it doesn't contribute to daily user experience in the way touchscreen controls do.
