Talking about the difference between a wireless monitoring of a wireless bridge and switch, wireless bridge wireless transmission function for the use of wireless (microwave) for remote data transmission interconnection point design. Come from understanding the role of the wireless bridge, it can be used to connect two or more separate network segments, these independent network segments are usually located in different buildings, a few hundred meters to tens of kilometers apart. The switch has only packet forwarding function free video surveillance cameras, do not have a wireless transmission function. Therefore, in a wireless monitoring system as a signal switch centralized role, and the wireless bridge to enable wireless video transmission capabilities. 2, when the switch is working, in fact, allow the passage between the ports of many groups simultaneously. Therefore, the function of the switch reflects more than just a wireless bridge function, but more than a collection of bridge functions. That is generally divided into a wireless bridge has two ports, and a high density switch ports. 3, due to the difference between sub-capacity switch can support multiple port video surveillance camera, so you can put the network systems division became more physical segment of mobile video surveillance cameras, which makes the entire network system has a higher bandwidth. The bridge only supports two ports, so the bridge dividing the physical network is quite limited. 4, the difference between the transmission rate compared with a switch wireless bridge data transfer rate, the switch faster than wireless bridge. At present, the transmission rate can reach Gigabit switch miniature video surveillance cameras, but can only achieve gigabit wireless bridge. Monitoring routine maintenance service mode 1. Periodic on-site service: According to customer demand, regular visits to customer systems and equipment maintenance and repair. 2. engineer stationed outside: send a qualified engineer resident customer site first line technical services. 3.7 × 24-hour response service: Service centers 7 × 24-hour emergency response service, once the customer's equipment or system failure, the service center will send engineers to customers within two hours of troubleshooting.
