Along with the rising of China tourism wave, cities across the country have hit the banner of green tourism, in order to attract tourists to travel, to promote the rapid development of local economy, but in the past two years, because of incomplete tourist attractions hardware facilities prevented many tourists enjoy, because tourists accounted for most of the proportion of foreign personnel, so its safety problems gradually become one of the tourist attractions concerns; Due to the large increase of tourists, the management has brought considerable pressure, but as a tourist attraction, it is impossible for us to maintain a large number of safety management personnel for a long time, and the increase of safety management personnel not only requires a large increase in capital, but also needs to be added in equipment. In terms of wireless communication equipment and command center, the E-LINS router provides both security and monitoring.

E-Lins router adopts industrial design, low power consumption, no fan, IP30 protection grade. Can work under harsh environmental conditions, such as high temperature, hot and humid, high dust environment. In this scheme, 4G wireless signals are used to go up to the operator's base station, and the service is transmitted to the monitoring center through the base station to realize real-time transmission of the service. At the same time, the service is connected to the camera through a large network cable through the downlink. Considering that most scenic spots are monitored in outdoor environment, industrial-grade routers can be used to achieve business access.
