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 an excellent provider of transmission products & services in the security industry, Feng Runda not only provides a variety of 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 selecting a wireless bridge (for users and users):
1. Operating frequency There are two kinds of operating frequency of the wireless bridge, 2.4G and 5.8G, the characteristics of the two kinds of 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 transmission rate of wireless bridge, such as 150Mbps, 3000Mbps, 450Mbps, 600Mbps, 900Mbps,etc., what kind of speed, can be decided according to the wireless monitoring requirement.
3. The antenna antenna is an important part of the wireless bridge. It is used to transmit and receive wireless signals. There is no antenna and the wireless bridge cannot communicate. 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. Since the power supply method is mostly used outdoors, such as reservoirs, forests, etc., if there is no power wiring, other power supply methods are required. The PoE-powered bridge is generally best.
5. Security Wireless bridges, like wireless routers and wireless APs, also require passwords or encryption of wireless signals. Otherwise, there will be many terminal accesses, which will affect wireless monitoring and transmission.
6. Waterproof, heat-resistant wireless bridges work more outdoors, the environment is changeable, such as rain, rain, snow, high temperature, etc., the main requirements of waterproof, dustproof, heat-resistant, anti-condensation. 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 The wireless monitoring project requires different transmission distances. The transmission distance of the wireless bridge is also varied. Some transmissions are 1 to 3 kilometers, some are transmitted 3 to 5 kilometers, and some transmissions are 5 to 10 kilometers. Some transmissions of more than 20 kilometers must be determined based on the monitored transmission distance. The maximum transmission distance of the bridge as far as possible is greater than the monitoring transmission distance.
Ceramic Force Control System
Our ceramic Force Control System, ceramic active contact flange, ceramic Constant Force Actuator have many advantages over other grinders. It can realize flexible grinding, quick repsond to surface changing, and instant adjusting. Traditional mechanic hand lacks flexibility, and it is not easy to adjust, hard to realize mass production.
