With the increasing use of high-definition network cameras, network monitoring system occupies the most important position in the security of our country, and Ethernet network switch is the indispensable equipment of the whole system, whether it is correctly configured directly affects the stability of the network monitoring system in the later stage. Ht3000r series is a product of industrial Ethernet switch series, which supports Poe function. The most important thing is to provide a reliable guarantee for network data transmission. When a node in the ring network is interrupted accidentally, the device can quickly switch links. The product supports Poe, gigabit optical fiber ring network, rapid switching in case of failure, automatic healing after failure recovery; automatic self-healing time, healing time is less than 20ms.

The scheme is mainly applied to video monitoring system, which connects the camera monitoring image and PTZ data of each monitoring point to HT3000R equipment network. The network of HT3000R equipment ensures the stability of data transmission, and transmits the data to 1000m network of HT3000R equipment through the upstream port of HT3000R equipment, which can transmit the remote monitoring terminal.
