How to install elevator monitoring efficiently

2022-08-29

    A friend asked me privately, is the business beyond the coverage of the mobile phone signal professional? After understanding, it turned out that I was looking for me to solve the mobile phone signal coverage of the elevator before, and now I am worried about the monitoring and installation of the elevator. In fact, I am also very professional in the wireless wifi bridge video transmitter.

    As the name suggests, a wireless bridge is a bridge of wireless networks, which uses wireless transmission to build a bridge of communication between two or more networks. In addition to the basic characteristics of wired network bridges, wireless network bridges work in 2.4G or 5.8G frequency bands that are exempt from applying for wireless licenses, so they are more convenient to deploy than other wired network equipment. Wireless bridge transmission standards often use 802.11b or 802.11g, 802.11a and 802.11n standards. The data rate of the 802.11b standard is 11Mbps. On the premise of maintaining sufficient data transmission bandwidth, 802.11b can usually provide 4Mbps to 6Mbps. 802.11g and 802.11a standard wireless bridges have a transmission bandwidth of 54Mbps, and the actual data rate can reach about 5 times that of 802.11b. Currently, the maximum transmission bandwidth through turb and Super modes can reach 108Mbps; 802.11n Usually can provide 150Mbps to 600Mbps transfer rate.

    Can't understand? It's okay, I'll explain it to you in the simplest terms right away.

    The traditional monitoring is to transmit video and images to the computer through network cables. I believe that if friends who have monitoring at home are clear, the installation monitoring requires a wiring, hiding the wires into the wire slot, and it may have to engage in the day and a half days. Especially for some long -distance monitoring installations, it takes a lot of time and cost to pull fiber. According to statistics, the construction cost of wired monitoring is dozens of times wireless, and the construction time is 20 times the wireless. Now, I tell you how these monitoring images are transmitted through wireless.

    Simply expressing is a pair of wireless network bridges sharing the same special network, and they follow the WiFi protocol, so they use WiFi's bandwidth. Then this dedicated network can simply understand the exclusive pairing. There is a bunch of envelopes on the desktop. The envelope is marked with numbers. The same number is a pair. Only the same numbers can disassemble the envelope to see the contents inside. Other people with different numbers do not know the contents of your envelope. Because they share the same special network, they may not borrow the Internet to transmit data.

    Then return to the elevator to monitor and install this one. Why do I recommend using a wireless network bridge? Elevator monitoring video transmission can be divided into two types: wired and wireless. Wired transmission uses professional elevator cables. Generally, the losses are severe during use, and the life span is half a year to one year. High -rise elevator cables have high requirements to fight stretching strength and electrical parameters. To prevent the stretching deformation from stretching and deformation when the cable is loaded from weight, the impedance is not matched, and the video signal signal signal -to -noise ratio is interfered. The construction of new accompanying cables is replaced again, the construction cycle is long, and the cost of replacing the accompanying cable is also high. The other is wireless transmission. The wireless transmission adopts a point -to -point method. A launch point and a receiving point are installed on the car. The data can be freely transmitted during the elevator car. The installation of wireless transmission equipment is simple and life expectancy for at least 5 years, and the bandwidth fully meets the requirements of HD monitoring video transmission.

    As shown in the wireless elevator network bridge in the picture, the LAN port is a network port, one of which is connected to the surveillance camera in the elevator, and one of which is connected to the computer of the monitoring party. There is no need to pull additional optical fibers to wire and transmit data, which is very convenient. In other places where it is inconvenient to obtain electricity, we can make the LAN port into a PoE port, and the network port with power does not need to find an additional power source.

    So, don't ask about wireless transmission of video data in the future, can it really be done? This is nothing new, and the cost is not high, most of which are cheaper than wired transmission.

    Well, I will share it here today. If you have any questions, you can comment below or privately message me.
