As the name implies, wireless bridges abandon traditional copper or fiber optics, use wireless communication technology, and connect two or more networks with point-to-point, point-to-multipoint or relay bridge design. In many complicated scenarios, many buildings that are far apart from each other are required to communicate with each other, and traditional wired transmission has many problems, such as:
1. Some environments with complicated environments are not convenient for wiring construction;
2. The general leased line cannot provide sufficient bandwidth;
3. Even if the price is not considered, some occasions cannot be leased to the line;
4. The management cost and complexity of multi-line routers are high;
The wireless bridge solution can avoid these problems well, mainly in the following aspects:
1. Save the installation cost of the special line and exempt the monthly fee;
2. Obtain long-distance, high-bandwidth wireless links;
3, a very short construction period, can be put into use after construction;
4. It is not subject to the restrictions of special places, only the on-site power supply guarantee is required;
5. Cost-effective point-to-point or point-to-multipoint WAN connection;
6, eliminate the high cost and high complexity brought by the management router;
7, heavy plasticity and scalability, easy to redeploy the network;
As there are so many advantages that point wireless bridge, which is from which parts of it?
Front-end acquisition equipment: The so-called front-end acquisition equipment is what we often call surveillance cameras, alarms, etc. It is generally used to collect audio and video data of monitoring points. The monitoring equipment with special functions can also collect the temperature, humidity and wind direction of the monitoring points. , wind speed and other data.
Intermediate wireless video transmission part: This part mainly includes wireless bridge transmitter, wireless bridge receiver, POE power supply module (generally including power adapter and power supply module), U-shaped clamp code for fixed transmitter and L-shaped bracket (for For fixed bridges, transmitter receiver feeders, bridge-specific antennas (some bridges have built-in antennas), and waterproof plugs (to prevent moisture from entering the interior of the wireless bridge).
The back end receives the display part: the back end receiving display part is a device capable of directly displaying the monitoring information, and the monitoring terminal user can easily grasp the alarm information, the monitoring screen and other information that the user wants to link, which is most commonly used. The monitoring terminals are NVR network DVR, hard disk (for recording surveillance video), switch (integrated data transmission to NVR and monitor), and monitor (monitor display).
In general, wireless bridges have the advantages of long transmission distance, unobstructed erection, and rapid networking. In the field of modern video surveillance transmission, more and more solutions are used to build monitoring systems using wireless bridges, which has become a modern monitoring system. The main application equipment of the industry.
