Video Call Intercom Based on IP System with Vibration Sensor

Abstract

Security at entry points is a critical requirement in residential and commercial environments. Traditional intercom systems provide only basic audio communication and depend on manual interaction, making them inefficient in detecting unauthorized access or intrusion attempts. Moreover, the absence of real-time video communication limits the ability of users to visually verify visitors. This paper presents a Video Call Intercom Based on IP System with Vibration Sensor, designed to enhance security through automatic intrusion detection and real-time video communication. The proposed system integrates a vibration sensor with an ESP32 microcontroller to continuously monitor abnormal vibrations such as door knocks, tampering, or forced entry. Upon detection, an alert is immediately transmitted to a backend server using IP-based communication. The system enables instant notification and supports live two-way video communication using WebRTC through a web browser. By eliminating the need for dedicated intercom hardware and providing browser-based access, the system offers a cost-effective, scalable, and efficient solution for modern security applications.
