A "riasztó" is a security device designed to alert individuals to potential threats, such as unauthorized entry or emergencies. These systems can include alarms, sensors, and cameras, which work together to detect unusual activity. When triggered, a riasztó emits loud sounds or sends notifications to the property owner or security services. Riasztók are commonly used in homes, businesses, and public spaces to enhance safety. They can be connected to a central monitoring system, allowing for real-time surveillance and response. Many modern riasztók also integrate with smart home technology, providing users with remote access and control through their smartphones.
