Classification and Application Range of 4G Communication in Monitoring Field

As 4G communication is a communication transmission mode and medium, it is not the exclusive way of monitoring, so the application type of 4G monitoring is attached to various security and monitoring equipment and systems. With the development of wireless and network wireless technology, the application of wireless broadband network is also adopted for various signal transmission, such as 4G network set camera, 4G network server, 4G post-transmission DVR and NVR, alarm and anti-theft detection, signal collection and transmission of access control and monitoring RTU that can accept remote data signal collection.

Compared with the traditional cable monitoring method, 4G wireless monitoring has the advantages of being free from the constraints of cable distance and wiring construction, short construction and installation time, easy maintenance and unrestricted system expansion in the future. Now 4G wireless network monitoring technology has been widely used in residential areas, urban traffic monitoring, bus transportation, railway crossing, reservoir and sluice control, regional river navigation, security, fire prevention and building automation monitoring, land security remote data collection and other fields.

In addition, after TD-LTE and FDD-LTE time-synchronous code multiple access, and after the commercial testing, China's 4G monitoring began to mature mobile 4G wireless broadband network application in 2014, and its application field will be more extensive.

In fact, domestic 4G wireless video monitoring has entered the growth spurt, especially in the bus and transport industries. The development from single vehicle system to 4G monitoring not only improves the past traffic monitoring and video recording to remote monitoring, but also realizes the collection and mastery of the training on the traffic condition, traffic safety and vehicle dynamics. It enables bus and public transport safety to achieve real-time remote monitoring in a short time. In addition to being "effective" for buses, the mobile 4G monitoring mentioned above can also be applied to emergency ambulances and fire trucks as a record of emergency rescue or relief process. In addition, the application of 4G monitoring in fixed monitoring can also spread charm in some areas that cannot be wired or have difficulties in power transmission. Up to now, the application promotion of 4G video for fixed and mobile monitoring has developed rapidly, and gradually spread from the public domain to the commercial transportation and private vehicle market, making various specific environments available for 4G wireless monitoring applications.
