Before the wireless monitoring system is networked, a detailed understanding of the on-site environment will be provided. To determine the number of cameras that need to be installed at the site, where they are distributed, whether they are blocked during transmission, and how far they are transmitted. Through the investigation of the on-site environment, it can be concluded how the wireless monitoring system is arranged.
Some common scenes have corners, corners, and blocking situations. The wireless monitoring network can be built normally by means of transit. Can Lean's wireless bridge transit? The answer is yes. All wireless bridges can transit. Will transits affect the effect of wireless transmission? If the transfer is repeated, it will cause some small delays. Usually, transiting four or five times will not have much impact. However, it is not recommended to transfer too many times, such as more than ten times, so that the load is too large and it is easy to cause the entire wireless monitoring system to be abnormal.
More common is a wireless monitoring system that transfers once or twice. One way to transfer, one or more transits on a transmission line is what we commonly call relay transmission. There is also a transfer at different transmission points in the same venue. No matter what kind, it can be carried out normally. Specifically, you can ask Ryan's technical staff to create a perfect solution for you.
I. Product introduction
LA-5839S is an outdoor wireless bridge that solves the wireless access in the last 1~5km range. It adopts the latest AR9342 processor and has stable operation, high reliability, and stable operation under high or low temperature environment. Dual channel RF output 26dbm (400MW), LA-5839S system integrated 5.8G, 18dbi dual-polarized antenna, the design of a stable transmission distance of 8 kilometers, 5 kilometers bi-directional transmission rate of up to 100M. Compared with the traditional laying of optical fiber, the cost is low and the efficiency is high. LA-5839S comes with frequency detection function, through its own software analysis function, can detect the scene of 5G signal equipment channel usage and intensity, optimize the spectrum and improve spectrum efficiency, the system has a watchdog function, to prevent crashes. The system is set up through IE, supports Chinese/English operation, facilitates the debugging of the engineer, can complete the connection between the devices, shorten the debugging time and work difficulty, and improve work efficiency.
