The wireless bridge consists of three steps:
Wireless bridges use point-to-point, point-to-multipoint, and relay bridging is designed to connect two or more networks (especially in different areas). The use of wireless bridges in wireless video surveillance systems to transmit video signals has the advantages of long transmission distance, high receiving sensitivity, long non-line-of-sight transmission distance, and clear and smooth images. The advantages of the wireless bridge are reflected in the following aspects: Wireless paving, high bandwidth, strong compatibility, unobstructed installation, mobile network, fast networking, uninterrupted network, structural flexibility, private network, Manageability is strong. Here we briefly introduce the wireless bridge video surveillance system components:
1, outdoor wireless bridge. Two or more outdoor wireless bridges can be used to connect separate LANs to each other.
2. High gain outdoor oriented or omnidirectional antenna. For the wireless network interconnection of outdoor long-distance stations, a high-gain outdoor oriented or omnidirectional antenna needs to be used in conjunction with the directional antenna. The omnidirectional antenna can realize a point-to-multipoint connection.
3, arrester. In order to ensure the normal operation of the wireless network system during thunderstorms, an arrester device is required. The surge generated when the feeder system is struck by lightning (or with a high-voltage magnetic field) does not enter the system equipment, and timely discharge of the surge through grounding ensures the safety of the system equipment and work.
4, power amplifier. In some cases where all power amplifiers are needed to improve coverage over longer distances, we can use power amplifiers.
In order to ensure the stability of the wireless monitoring system, it is very important to make lightning protection and waterproofing of the wireless bridge in the wireless video surveillance system. Waterproofing at the festival head is even more important.
