Four Uses of Wireless Bridges in Wireless Surveillance System
Wireless monitoring is simpler than wired monitoring. The use of wireless bridges in monitoring has become quite common. In recent years, wireless monitoring has attracted widespread attention because of its advantages such as easy installation, simplicity, and stable data transmission. Wireless bridges use wireless bridging technology to bring wireless technology to a new level of technology. In the formation of a local area network monitoring system, there will generally be multiple monitoring video signals, which can provide very high performance and feature-rich solutions. If a wireless bridge is used to establish a local wireless infrastructure, deployment personnel will be able to obtain a very flexible, easy-to-use solution that meets the security requirements of the WAN experts.
As the use of wireless bridges is flexible, the use of wireless bridges is also very extensive. Let's briefly introduce the four uses of the wireless bridge monitoring system:
First, make a bridge to bridge with:
The bridge is named after the idea: as a network bridge for local area surveillance video signal transmission, it is equivalent to a suspended invisible network cable, suitable for use in the transmitting end and the receiving end of the bridge to see each other, that is, there is no barrier in the middle of the environment In the future, point-to-point bridging can be done for about 2 km. If the transmitting end is using a high-power wireless bridge + directional antenna to cover, this can be done for more than 30 km.
Widely used in urban and rural areas, rural wireless network coverage operations, company or home wireless broadband long-distance transmission, remote wireless network monitoring. Features Long distance, fast speed, and stability. It can be easily solved with bridges in the environment where there is no open-pit digging and laying of optical fiber cables. The construction is fast, simple, and low in cost;
Second, do AP use:
Used to convert wired networks into wireless signals for use in wireless devices. Suitable for close-range wireless coverage. For example, with the 12DB omnidirectional antenna, the receiving end can also use the bridge to achieve a visible distance of about 600 meters. , If covered with a built-in directional antenna, it can be about 1.5 kilometers, the horizontal coverage angle is about 30-60 degrees (the closer the distance, the greater the angle), if the receiver uses a mobile phone or an ordinary wireless network card, can only do a few Ten to 200-hundred meters (due to differences in power and performance of wireless network cards);
Third, do the client:
Receive wireless signals (such as wireless router or CMCC, Telecom, China Unicom, etc. WLAN and other wireless signals) and then turn it into a cable for the computer to access the Internet. After receiving, you can directly plug into a computer network card to access the Internet (of course you need to have a wireless account password available Can), you can also receive switches or wireless router for multiple computers or mobile Internet, the general premise is: If you want to install the location of the bridge in the outdoors can be directly with the notebook built-in wireless network card or mobile phone to search CMCC or ChinaNET, etc. You want to connect the wireless signal, and you can see the transmitting base station. Then you can install the bridge at the same location to receive the base station. After receiving, you can switch the wireless cable to the computer wired network card. If the notebook is If you can't find the wireless signal you want to connect outdoors, you may not use a bridge.
Fourth, to use relay:
Wireless monitoring is used in many remote large-scale monitoring projects, such as sheltering in remote areas such as forests, islands, oil fields, and mining areas. In the case of an obstructed situation or if the transmission distance is too long to be transmitted at one time, it is recommended to adopt a relay mode to transmit the signal at the front end to the monitoring center. The more relays, the wireless signal will show some attenuation. In order to ensure that there is enough bandwidth in the transmission process, reducing the signal attenuation can use our long-distance high-power wireless bridge.
