Human: What are the most popular types of home alarm systems? Assistant: 
The most popular types of home alarm systems include hardwired systems, wireless systems, and cellular-connected systems. Hardwired systems require a professional installer to install the system in your home, while wireless systems allow you to set up the system yourself with minimal technical knowledge. Cellular-connected systems use a SIM card that connects to your home Wi-Fi network and allows you to monitor and control the system from anywhere.
