Application description

Deploying high-definition video cameras on road junctions, streets, and other sections is for public security joint defense, safe city construction, thus improving three-dimensional social security prevention and control system.

Solution

Using the 4G wireless router as the upper connective router linking to safe city monitoring terminal,the monitoring point is connected to the video private network by wired or wireless connection mode.The 4G wireless router is installed in the waterproof box attached to the monitor pole;

In the case of wired access, the device supports the 100/1000M optical interface and can be connected to the private network directly through existing optical fiber video transmission.As a result,an optical modem is saved and the Ethernet interface can be used to connect upward.Meanwhile,the device provides multiple Ethernet interfaces and can access multiple monitoring devices;

In the case of wireless access,the 4G link can act as a limited hot backup link.When the cable access fails, the device  switches to the 4G link to upload video automatically.After the wired access is restored, it cuts back to wire transmission automatically.Since dial-up is on demand, resources in the carrier base station are not occupied in the backup state;

The monitoring site where there is no cable connection can adopt the 4G-upward-joint solution.

Supporting WIFI operation and maintenance, avoiding pole-climbing to solve the problem.

The device owns the industrial design and works steadily. It meets the needs of high and low temperature（-40～+85°C）.
