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 are all must. Due to space concerns, the EX74000 and the NVR are installed in a compact box. Therefore, the size of all related networking units also has to be minimized. As seamless data transmission and smooth image delivery are required from Etherwan’s W4281 Hardened IP68 Dual Radio Multi-function PoE Wireless Devices, their proper installation, including the appropriate antenna selection and installation angle, is crucial.

The solution is initially installed in one zone only, in order to guarantee that the wireless data transmission is satisfactory. After one month of positive results from the field tests, the solution has established in other zones. The resort investors are now able to view the construction progress at anytime and obtain real-time updates. This solution becomes a service available to all resort investors.
