What is wireless transmission equipment of wireless monitoring system?

The wireless bridge that we often talk about in wireless monitoring, how to achieve wireless monitoring transmission? As the name implies, wireless surveillance generally transmits video or data signals through microwaves, and realizes real-time transmission of network audio and video data through transmission and reception docking. Except for transmitting and receiving, other parts are the same as traditional closed-circuit monitoring. A wireless transmission device has been added to the intermediate transmission section.

In recent years, the tide of wireless monitoring is flooding into the application of security monitoring projects. In this rapid development trend, more and more engineering projects are being put into wireless monitoring systems. Ryan has also received a variety of telephone consultations. It may not be very clear what kind of requirements the wireless surveillance can achieve. Especially when the wireless surveillance system brings us great convenience, what can we do to make wireless? Is monitoring stable and effective?

Let's discuss some of the requirements and features of the wireless monitoring system and learn more about a more realistic wireless monitoring system.

Wireless monitoring environment requirements: wireless monitoring system is required for the environment, like the wireless bridge is used more than 2.4G and 5.8G2 frequency bands, but no matter which frequency band, are required to be open environment, Can't be blocked. Of course, the current COFDM technology is also very mature, and this kind of transmission equipment in the wireless monitoring system can achieve a certain distance transmission under the condition of shelter. Not to mention the rapid development of 4G transmission equipment, as long as there are 4G networks, these distances are not a problem.

Wireless monitoring system bandwidth: With the advent of high-definition era, the clarity of the video signal is also getting higher and higher. So, correspondingly, Levin wireless monitoring system has 300M, 800M, 1000M equipment, which can meet different bandwidth requirements. However, the bandwidth calculation method of the wireless monitoring system is different from the bandwidth calculation method of the wired monitoring. For cable monitoring, the marked bandwidth is basically the standard of one-way transmission capability. For wireless monitoring, this figure becomes the sum of the uplink and downlink transmission bandwidth. Therefore, when we calculate the bandwidth transmission of the wireless monitoring system, we must be clear about the actual bandwidth requirements in the project. Only in this way can we be able to provide more suitable transmission equipment for the wireless system. In addition, because the wireless systems are installed outdoors, the environment or the weather has a great influence on the equipment. Therefore, the transmission bandwidth in practical use cannot be fully loaded. In the calculation, the use only accounts for about one fourth of our theoretical value. This also requires us to set aside sufficient space for the system to ensure that our monitoring equipment will not be able to work properly due to changes in the environment.

Some common sense of wireless monitoring system installation : Maintaining the distance between the front end and the terminal and the wireless device For the monitoring of large-scale environments, the appearance of the wireless monitoring system can save most of the wiring troubles. However, many times, due to environmental factors, we must install the equipment outdoors or even at a height, which will create a distance between the device and the camera and the video recorder of the room. Therefore, we need to understand that the camera-to-transmitter and video recorder-to-receiver The extent to which the cable between the machines can control the attenuation of the equipment is minimal.

The network cable connected in the wireless monitor explains: Generally, digital microwaves, cameras and transmitters are connected through network cables. The quality of the network cables affects the transmission efficiency of the signals. A good network cable can be extended to a maximum length of 100 meters, and the antenna and the host The longest feeder should not exceed 10 meters. Of course, for tens of kilometers of equipment are installed on the tower, how do we deal with the distance between the host and the antenna, we need to shorten the feeder and extend the cable.

The above points hope to give the majority of engineering companies a certain degree of awareness of wireless monitoring systems. If anything is unclear, it is best to call Levin directly.
