Abstract: The invention provides a software-based video call intercom system designed to enable seamless indoor communication for Deaf and hard-of-hearing individuals. The system operates entirely through software using real-time video calling, speech-to-text conversion, and optional sign-language recognition to eliminate reliance on sound. Communication is supported by WebRTC for peer-to-peer video transmission, while a lightweight signalling server manages connection setup within a home, office, or institutional network. A vibration-alert mechanism further enhances accessibility by notifying Deaf users of incoming calls through a wearable or connected haptic device. This invention improves traditional intercom systems by offering a low-cost, accessible, and fully digital solution that removes the need for physical wiring or hardware units. The platform ensures secure, instant communication and provides an assistive environment where both Deaf and non-deaf users can interact effectively through visual cues, text, and vibration feedback. By integrating video communication, accessibility features, and inclusive interaction methods into one system, the invention serves as a practical and scalable tool for modern indoor communication.
