A bus network monitoring system

Abstract

Twisted pair lines and HUB are used to connect more than two IP net work cameras of different IP addresses and one twisted pair line is used to connect the next stage HUB and other network cameras of different addresses, network cameras of different IP addresses are connected in the same way then to connect with the network monitoring system host, which is connected to the monitor and network to realize the control.

Description

Technical field: [0001] The invention relates to a network monitoring system, in particular to a bus system network monitoring system. Background technique: [0002] At present, the structure of the commonly used monitoring system is: 1. The front-end analog camera is connected to the monitoring host with a video cable, and the image is saved, monitored and connected to the Internet by the monitoring host. In the above structure, all the analog cameras need to use A video cable is used to transmit video signals, that is to say, a video cable can only transmit one video signal. If multiple places need to be monitored, a video cable must be laid at each corresponding monitoring point to the monitoring host. Due to the diversity of monitors and monitors, the cost and difficulty of laying cables must be increased, so that the monitoring of large areas is limited. 2. IP network cameras use twisted pairs to realize remote monitoring through the Internet, but at present, IP networ...

If multiple places need to be monitored, a video cable must be laid at each corresponding monitoring point to the monitoring host. Due to the variety of monitors and monitors, the cost and difficulty of laying cables must be increased, which limits the monitoring of large areas

2. IP network cameras use twisted pairs to realize remote monitoring through the Internet, but at present, IP network cameras all need public network fixed IP support, and each IP network camera needs a public network IP, which shows that the daily operation of IP network cameras requires The monthly rent is expensive. Today, IP network cameras are difficult to promote in the face of shortage of IP resources and high network costs. The main fatal shortcoming of IP network cameras is that they do not have the function of saving images locally, and users have to use another set of equipment. , remote video recording through the Internet, the instability of the network has caused many obstacles to the promotion and use of IP network cameras
