Communication Solution for Security & Protection

The complete security monitoring communication system builds a layered industrial Ethernet network. Optical fibers are adopted for long-distance interconnection between switches, with support for ring network redundancy. Access switches connect front-end security devices including perimeter cameras, access control systems, alarm devices, indoor PTZ cameras and more. Service data is converged uniformly and transmitted to the DVR for storage, with output to monitoring displays.

The system implements VLAN and QoS mechanisms to isolate traffic of different services and prioritize the transmission of surveillance video. It effectively avoids network congestion and mutual service interference caused by concurrent transmission of multiple devices, enabling efficient and stable transmission of security monitoring data.
