Intercom
An intercom is a communication system that allows for two-way audio communication between individuals or groups in different locations within a building, facility, or vehicle. It typically consists of interconnected speaker and microphone units, often with a central control panel for managing communication channels. Intercoms can be wired or wireless and are commonly used for security, convenience, and efficiency purposes in homes, offices, hospitals, schools, and industrial settings. They facilitate quick and easy communication between rooms or areas, enabling instant communication for emergencies, coordination of tasks, and convenience in everyday interactions without the need for physical proximity.
