Safety City Monitoring System

MRD^™子午线^®——Smart City System Overview

Smart City in China is a extra-large comprehensive information management system which is led by the Ministry of Public Security and the purpose is to maintain the social harmony and stability. It cooperates with technical protection system、material protection system、people protection system to meet actual requirements of social security、criminal investigation and disaster prevention.

The main component of Smart City System is the video monitoring system and it can utilize the urban level data exchange platform to realize resource sharing. The hardware part mainly includes front-end camera、middle-end network products (router and switch)、server、back-end DVR/NVR and monitor in the system.

MRD^™子午线^®——Features of Smart City Monitoring System

Meet the environment temperature、 dust-proof and EMC and other harsh requirements in the transportation industry.

Each crossing can be equipped with 1～4 switches with an interval of 100～500 meters.

Aggregation node access the center through cascade or ring networking.

Ring network self-healing, the link recovery time is less than 50ms.

Hierarchical Networking scheme, perfect network management SNMP and friendly web interface.

Supporting POE function to solve the power supply of the last 100 meters.

Small size, compact and flexible, easy to install on site.

MRD^™子午线^®——Typical Topology for Smart City Monitoring System

MRD^™子午线^®——Trend of Smart City Monitoring System

1.Cloud data storage. Multi monitoring points and large amounts of image information, storage time 7×24h, urgent requirement for massive HD video;

2.Diversified network access. With the expansion of smart city construction, the network access methods should be more flexible and low-cost;

3.Using the data intelligently and safely, including trajectory analysis、intelligent object retrieval、face recognition、motion detection technology、video abstraction technology、graphic drawing and layout analysis algorithms and so on；

4.Cluster unified management. It will be a trend that the video monitoring management platform has unified management capability and strong compatibility；

5.Urban environment is different from the environment of standard machine room. It should adopts the network device with high MTBF and high Lifetime to ensure the overall reliability and stability of the system；
