A SIP-Based Video Door Phone is a modern, IP-enabled communication and access control device that uses SIP (Session Initiation Protocol) – the same protocol used in VoIP telephony – to enable audio and video calls over IP networks. It provides real-time communication between visitors at the door and occupants inside, offering remote access, control, and integration with existing VoIP systems. This solution is ideal for smart buildings, enterprises, gated communities, hotels, hospitals, and modern residences where secure, flexible, and scalable communication is required.
