Network monitoring transmission system based on POE switch and EOC

How to use the simplest solution to form a network monitoring transmission system is the most urgent problem that security engineering companies need to solve in the process of building network high-definition video monitoring systems in recent years. Because in the monitoring system, simplicity means higher stability and reliability of the system, which means lower construction and maintenance costs.

　　Influenced by traditional network transmission technology, people generally use network cables and network switches to solve the transmission of short- and medium-distance network monitoring signals inside buildings, and use optical fibers and optical fiber transceivers to solve the transmission of total data or ultra-long-distance outdoor monitoring signals. However, with the development of the demand for expanding the monitoring range and the emergence of large and ultra-large buildings, the cascading method of ordinary network switches with an actual extension distance of only 80-100 meters is no longer sufficient. As the number of switch cascades increases, the system network becomes more and more complex, which will inevitably reduce the stability and reliability of the system and produce obvious network delays, thus seriously affecting the overall performance of the system, and also raising the project cost and construction difficulty. Therefore, many people consider simply introducing optical fibers directly into the internal networking of the building, but on the one hand, optical fibers are not convenient for wiring, and on the other hand, optical fiber joint welding requires professional equipment and professional technicians. Therefore, the use of optical fiber access for short and medium distances is not only difficult to construct and costly, but also not the most ideal solution after all.

　　In response to the difficulties encountered in networking and deployment of new network HD video surveillance projects and more and more analog surveillance upgrade and network surveillance renovation projects, Shenzhen Utop Technology Co., Ltd. has launched POE and EOC product solutions to provide more innovative solutions and options for the engineering design and construction of network HD video surveillance transmission systems:

　　1. POE transmits power and network together

　　As mentioned above, the traditional network monitoring transmission scheme, especially within the range of 1000 meters, mainly has the problems that the equipment extension distance does not match the actual project needs, and the network equipment such as power supply and switching is complicated and not conducive to construction and maintenance. Utop recommends that you choose a 250-meter or 100-meter POE network switch according to the actual situation to meet the medium and short-distance transmission requirements in the building, and use a combination of POE network fiber transceivers for outdoor ultra-long-distance transmission. This can fully meet the requirements of modern network high-definition video surveillance new projects for network bandwidth and transmission distance. Because the network switches and network fiber transceivers developed by Utop using POE technology can extend the high-speed network signal while also providing a stable DC power supply for network cameras with POE receiving functions and network devices such as IP phones at the front end, so that there is no need to consider the power supply and wiring issues for the front-end camera in engineering design, reduce the use of cables, and improve electricity safety. In addition, Utop's 250-meter long-distance POE network switch has a transmission distance much longer than ordinary network switches. In engineering applications, it can reduce the number of cascade installations of switches, greatly reduce the cost and difficulty of construction and maintenance of the project, and make the overall performance of the system more stable and reliable.

2. EOC uses coaxial cables and other cables to transmit the network

　　As we all know, in the past, most analog monitoring systems used coaxial cables as transmission media, and the general practice was to use one coaxial cable to transmit one video signal. However, now network HD monitoring systems usually need to use network cables as transmission media. Therefore, in the system transformation project, it is necessary to remove all the cables that have been laid in the past and then re-lay the network cables. On the one hand, this will waste a lot of wires and consume huge material and labor costs. On the other hand, the indoor environment of hardcover hotels and banks will inevitably be severely damaged, making the owners feel that the gains do not outweigh the losses, and finally give up the choice of network HD monitoring systems, which also affects and restricts the further popularization and application of network HD monitoring system products. In response to this practical problem, the EOC network extender developed by Utop only needs to use ordinary coaxial cables or single-pair network cables, telephone lines or even idle wires to transmit high-speed network signals, and achieve a maximum transmission distance of 1500 meters and a maximum bandwidth of 134 megabits. Taking the transmission distance of 300 meters as an example, this product can meet the data transmission requirements of more than 10 megapixel high-definition network cameras through one coaxial cable. This not only realizes the desire of the network high-definition monitoring system transformation project without rewiring, but also further expands the system radiation range. At the same time, it minimizes the project cost.

　　It is worth mentioning that the EOC series products of UTEPU are a new type of network extension equipment developed based on VDSL2 technology. In actual engineering applications, it can also transmit telephone signals while transmitting network signals. Therefore, we can use the original data lines in environments such as elevators to transmit network signals without delaying the use of telephones. It can be said to be a revolutionary solution for the current network high-definition video surveillance transmission system.
