Comparison of wireless bridge, COFDM wireless video transmission equipment and 4G transmission equipment
The mainstream wireless surveillance market now consists of wireless bridges, COFDM wireless video transmission equipment, and 4G transmission equipment. These types of equipment are used on different occasions and there is no absolute advantage or disadvantage. Lean Xiaobian gives you an analysis of the application of these three transmission methods.
First, the scope of application of wireless bridge
Wireless bridges are relatively cheap compared to the other two methods. In some fixed areas, such as factory areas, construction sites, river courses, forest fire prevention, and lakes, there are more points and fixed distances. With only one investment, installation and commissioning are simple, and subsequent expansion is easy. However, the wireless bridge must be within the visual range, that is, without obstacles.
The wireless network bridge of Lai'an has different equipments at different distances. The farthest point-to-point transmission under the visual environment can reach 100 kilometers.
Second, the application range of COFDM wireless video transmission equipment COFDM technology breaks through the environmental limits of the wireless bridge, can also be transmitted within a certain distance in the non-visual environment. Applicable to some mobile video transmissions such as ships, patrol cars, and drones. According to different use requirements, there are portable, vehicle-mounted, compact and compact type.
Lehman's single-armed standard can be used on robots and can achieve a transmission distance of about 3 kilometers in urban environments.
Third, 4G wireless transmission equipment
4G equipment completely breaks the limit of space distance. As long as there is a 4G network, no matter where and when the video can be transmitted, as long as there is a network, it can be monitored in real time.
At present, Lean has released a 4G high-definition cloth control ball, which is easy to carry and high-definition pixels.
It does not mean that which one is absolutely good depends on whether or not your environment is applicable.
