EtherWAN Supports Network Infrastructure for Monitoring Systems in Resort Construction



Internet Data Centers

EtherWAN works with solution partners in Asia, with a hardened managed PoE switch and ruggedized wireless AP, to form a complete real-time monitoring system in a hillside resort construction project. When construction begins, progress can be automatically reported through a real-time monitoring system backed by Ethernet technology and the process can also be effectively managed.

In this parcel of undeveloped land, there is no infrastructure and power sources are either not available or are limited. Therefore, wireless data transmission and PoE networking (Power over Ethernet) are the key technologies used to create this solution. There are two to three cameras installed in each zone, and each camera is connected to the EtherWAN’s EX74000 hardened PoE managed switch. Some zones use speed dome cameras, which consume more power, while other zones use regular cameras. The EX74000 is compliant with IEEE802.3af with high-power support in order to satisfy all scenarios. All of the different zones are connected via the EX74000 to form a ring topology to guarantee network redundancy. All captured images are stored in a NVR, which is directly connected to the EX74000.

All of the network equipment is installed outdoors; therefore, a rugged design in terms of the IP rating and a wider operating temperature range is required. Due to space concerns, the EX74000 and the NVR are installed in a compact cabinet. Therefore, the size of all related networking units has to be minimized. As seamless data transmission and smooth image delivery are required from EtherWAN’s W4281 Hardened IP68 Multi-function Dual Radio Multi, their proper installation, including the appropriate antenna selection and installation angle, is crucial in delivering reliable communication.

The solution allows resort investors to view the construction progress at anytime and obtain real-time updates. This solution is a service available to all resort investors.
