AI Technical Summary
Existing elevator IoT video intercom technology based on the FreeSwitch solution has poor scalability and serious bandwidth waste when there are many elevators, and it cannot achieve efficient video intercom between smart screen devices and front-end or mobile devices.
A WebRTC connection is created through a front-end or mobile device, an offerSDP is generated, and a video intercom connection is established with the smart screen through data forwarding and signaling services. Data forwarding and signaling services are deployed using a central server or cloud to manage the connection and optimize network performance, thereby achieving two-way audio and video transmission.
It enables real-time, high-quality video intercom between the front-end or mobile terminal and the smart screen terminal, simplifies the connection negotiation process, reduces the burden on equipment, improves the reliability and scalability of the system, and supports large-scale applications.
