When choosing a wireless bridge, where do you start from?
Wireless bridge is a kind of wireless monitoring equipment widely used in wireless monitoring field. Although it is a wireless device like wireless AP and wireless router, it is not used to build wifi, but is used to transmit video data wirelessly. Like the switch in cable monitoring, wireless bridge is an important transmission device in wireless monitoring, which shows its importance.
There are many types of wireless bridges on the market, people do not know where to choose, nor do they know how to choose the most suitable and most suitable one. As a provider of transmission products & services for the security industry leader XIAN, L&A not only provides multiple wireless bridges, but also allows users to use and use wireless bridges. This sums up several more important technical indicators.
Technical indicators to consider when choosing a wireless bridge:
1, working frequency
Wireless bridges have two operating frequencies, 2.4G and 5.8G. The characteristics of the two bridges are different. In general, the 2.4G wireless bridge is a mainstream frequency band with good compatibility and good diffractive power, but its anti-interference performance is relatively poor. 5.8G wireless bridge is relatively clean, anti-interference ability is better, the transmission distance is far, but the diffraction ability is poor.
2, transmission rate
There are many kinds of wireless bridge transmission rate, such as 150Mbps, 3000Mbps, 450Mbps, 600Mbps, 900Mbps, etc., what kind of speed, according to the wireless monitoring requirements.
3, antenna
The antenna is an important part of the wireless bridge, used to transmit and receive wireless signals, there is no antenna, wireless bridge can not achieve communication. There are many kinds of antennas, such as omnidirectional antennas and directional antennas. The larger the antenna gain, the better the performance of wireless bridges.
4, power supply
Because it is used outdoors, such as reservoirs, forests, etc., if there is no power supply wiring, you need to use other power supply methods. The PoE-powered bridge is generally the most JIA.
5, security
Wireless bridges, like wireless routers and wireless APs, also need to set passwords or encrypt wireless signals. Otherwise, there will be many terminal accesses, which will affect wireless monitoring and transmission.
6, waterproof, heat-resistant
Wireless bridges work outdoors, and the environment is changeable. Rain, rain, snow, and high temperatures are the main requirements. Waterproof, dustproof, heat-resistant, and anti-condensation are the main requirements. A qualified wireless bridge, these "quality" is a must.
7, stability
The stability of the wireless bridge is very important. If it works normally, it will crash for a while and the rate will slow down. This is related to the wireless bridge hardware, such as chips, motherboards, memory, cache, and so on. Of course, in a stable wireless bridge, if you do not make good in the later installation, it is no good.
8, transmission distance
Wireless monitoring projects require different transmission distances. There are also many types of transmission distances for wireless bridges. Some transmissions range from 1 to 3 kilometers, some transmit from 3 to 5 kilometers, some transmit from 5 to 10 kilometers, and some transmit from 20 to 20 kilometers. Above the km, it must be determined according to the monitored transmission distance. As far as possible, the maximum transmission distance of the bridge is greater than the monitoring transmission distance.
Of course, if you don't know how to choose a wireless bridge, you can call Levin Technology and the staff will give the most suitable configuration according to your actual situation.
