The
First, the scene
A video surveillance system needs to be installed on an island in Huizhou, and four-way video of the dock and construction site will be transmitted to a monitoring center more than 10 kilometers away. Because of the seawater barrier, it was illegally transmitted in a wired manner. Customers had also thought of using 3G networks. However, 3G network signals were often unstable and the picture quality could not meet the requirements, and the traffic charges in the later period were too high. The use of wireless monitoring is the best choice.
The
Second, the solution
Taking into account the longer transmission distance and high-definition video transmission, using UBNT 5.8GHZ transmission. The 4-channel video signal on the island is pulled together and connected to a network hard disk recorder to convert the analog signal into a digital signal. The 4-channel signal is transmitted to the UBNT 5.8GHZ digital microwave transmitter through a network cable. 15 km away from the monitoring center. After receiving the signal, the monitoring center directly receives the computer and watches it on the computer.
The
Third, the transmission principle:
Transmitter: 4-channel analog video + network hard disk recorder + UBNT 5.8GHZ digital microwave transmission system
Receiver: UBNT 5.8GHZ Digital Microwave Receiver System + Computer
The
UBNT 5.8GHZ is a wireless microwave device with built-in 27DB dual-polarized antenna, wireless high-bandwidth bridge, transmitting power 500mW, high receiving sensitivity, 802.11 a/n protocol, 300Mbps, net bandwidth over 150Mbps, stable product, high power, Microwave devices support 802.11n and MIMO technologies. Excellent product receiving performance and extremely high transmission speed (net bandwidth over 150Mbps, TCP/IP). The device is specifically configured for outdoor point-to-point and point-to-multipoint AirMax base station applications and is best suited for wireless HD network monitoring.
