A home security system is a collection of devices designed to protect a residence from intruders and other threats. These systems often include components like alarms, cameras, and motion sensors that work together to detect unauthorized access or unusual activity. When triggered, the system can alert homeowners or notify local authorities. Many modern home security systems can be controlled remotely through smartphones or tablets, allowing users to monitor their property in real-time. Some systems also offer features like video surveillance and smart locks, enhancing overall safety and convenience for homeowners.
