•RS485Interface (future support)CANInterface), using an isolation circuit to connect to the elevator motherboard, to achieve the transmission of elevator IoT information to the monitoring center or manufacturer's backend.

•Network interface, providing 1 RJ45 orBNCInterface (according to on-site requirements): Unique Ethernet extension technology, in5Non shielded network cable transmission distance500Rice（100M）The farthest distance can be reached1000Rice（10M )Transmission over dual core wires（RVVline300rice10M）In coaxial cable transmission distance1800Rice（75-5Line,100MBandwidth).

•1 fiber optic port: multimode SC/ST fiber port single-mode SC/FC fiber port, single-mode fiber transmitter distance of tens of kilometers

•4GAccess to Wide Area Network (optional for customers)

•Implementation method: Connect with the four-way intercom inside the elevator, and enable two-way communication with the monitoring center host through the local area network; Linked with IP cameras through an IP five party intercom gateway and designated IP cameras, video viewing of the elevator car's condition can be achieved during communication.
