In the wireless monitoring system, wireless monitoring equipment in the following four categories: 3G wireless monitoring equipment, 4G wireless video transmission equipment, microwave wireless monitoring equipment, WIFI wireless monitoring equipment. At present, these types of devices are not unfamiliar to everyone. Wireless signals can be seen everywhere in our lives. Then what is their use in wireless monitoring systems? What is the difference between them? Here's a brief introduction:
1. 3G wireless monitoring equipment 3G wireless monitoring is a simple and easy-to-use small-scale remote wireless monitoring system. It adopts the latest 3G communication technology and targets the needs of home, small-sized enterprises or users in certain industries. It has designed and implemented an installation. Simple, easy-to-use, cost-effective 3G mobile video surveillance device. The advantages of 3G wireless monitoring equipment are:
The investment in the early stage is very low, and it is very convenient to install and use. As long as there is coverage of the 3G signal, you can turn on the device to transmit signals.
The disadvantage of 3G wireless monitoring equipment is that the late-stage charges are relatively large and are not suitable for long-term 24-hour monitoring. At present, the transmission of this kind of transmission signal to the image is not very smooth, and the quality of the transmission image is not high enough, and the requirement for high-definition transmission cannot be achieved at all.
2, 4G wireless video transmission equipment 4G is the abbreviation of the fourth generation mobile communication technology. China Mobile 4G adopts TD-LTE in the 4GLTE standard.
The theoretical peak transmission rate of the TD-LTE demonstration network can reach downlink 100Mbps and uplink 50Mbps. TD-LTE is a 4G network standard that is dominated by China. The technology is mature, and it has the conditions for large-scale promotion. Currently, it has been officially commercialized.
4G wireless video transmission equipment is a communication technology formed after 3G wireless monitoring equipment. It integrates 3G and WLAN and can quickly transmit data, high quality, audio, video and images.
The advantages of 4G wireless video transmission equipment are: 4G wireless video has a higher transmission rate and can transmit video images with high quality. It can provide a more stable and adjusted wireless mobile network. The investment in the early stage is very low, and it is very convenient to install and use. As long as there is 4G signal coverage, you can turn on the device to transmit signals.
The disadvantage of 4G wireless monitoring equipment is that the communication costs in the later period are relatively large and it is not suitable for long-term 24-hour monitoring.
3, microwave wireless monitoring device <br> <br> microwave wireless monitoring device is currently the main LIU products on the market, the wireless monitoring device is the perfect microwave transmission technology and wireless monitoring technology combination. Microwave wireless monitoring can be divided into analog microwave and digital microwave two ways.
Analog microwave transmission is to directly modulate the video signal on the microwave channel (microwave transmitter) and transmit it through the antenna. The monitoring center receives the microwave signal through the antenna, and then demodulates the original video signal through the microwave receiver. This monitoring method is very clear image, there is no delay, no compression loss, low cost, simple construction and debugging, suitable for general monitoring point is not many, need to use the relay is not much.
Digital microwave transmission is a wireless bridge, that is, video coding is first compressed, then modulated by a digital microwave channel, and then transmitted through the antenna, the receiving end is the opposite, the antenna receives the signal, microwave despreading, video decompression, shrimp reduction simulation The video signal can also be decompressed after microwave installation of the corresponding decoding software through the computer, using computer software to decompress the video, and the computer also supports video, playback, management, PTZ control, alarm control and other functions; this monitoring method is more complex, Need to add more relay situation, more concentrated monitoring point it can focus on the transmission of multi-channel video, anti-jamming capability is better than the simulation, and so on, for more monitoring points, the need for more relay use.
Microwave wireless monitoring equipment advantages: low investment costs, transmission distance, anti-interference is very good, clear and smooth transmission of images, suitable for outdoor transmission under various harsh environments. Disadvantages of microwave wireless monitoring equipment: high requirements on the environment, we must carry out signal transmission in an open environment, the diffraction ability is very poor.
4, WIFI wireless monitoring equipment WIFI (WirelessFidelity, wireless compatibility certification) official name is "IEEE802.11b", and Bluetooth, belong to the short-range wireless technology used in the office and home. Although in terms of data security, this technology is worse than Bluetooth technology, it is slightly better in terms of radio coverage.
The coverage of WIFI can reach about 300 feet (90 meters), and the office will need to use it even in the smaller whole building.
The WIFI band is a free band that does not require any telecommunication operating licenses worldwide, so WLAN wireless devices provide a wireless air interface that can be used worldwide, at a very low cost, and with extremely high data bandwidth.
The advantages of WIFI wireless devices: The investment cost is very low, and the installation and use are very convenient. No professional can also set up the network.
Disadvantages of WIFI wireless monitoring equipment: the transmission distance is short, and it can only transmit signals within close range, and the diffractive power is also very poor. Avoid the shielding when the signal is transmitted.
