Sisäpuhelin

Sisäpuhelin, also known as an intercom system, is a telecommunication device used for voice communication within a building or a confined area. It allows for two-way communication between different points without the need for external telephone lines. Typically, a sisäpuhelin system consists of a master unit and one or more remote units, or multiple interconnected units.

These systems are commonly found in homes, offices, hospitals, and industrial facilities. In residential settings, they can connect different rooms, allowing for easy communication with family members or monitoring of children. In commercial environments, sisäpuhelin systems facilitate communication between reception areas, offices, and other departments. They are also used for security purposes, enabling communication with visitors at an entrance before granting access.

Sisäpuhelin systems can vary in complexity, from simple wired installations to more advanced wireless or IP-based systems. Basic systems often use a dedicated wiring infrastructure, while wireless versions utilize radio frequencies. IP-based systems integrate with computer networks, offering features like integration with other communication platforms and remote access. The primary function remains the same: to provide a convenient and immediate means of voice communication within a localized environment.
