How to form the network monitoring transmission system with the simplest solution is the most urgent problem to be solved in the construction process of the network engineering of high-definition video surveillance system by security engineering companies in recent years. Because in the monitoring system, simplicity means that the stability and reliability of the system is higher, which means that the cost of construction and maintenance is lower.
Affected by the traditional network transmission technology, everyone generally uses network cables and network switches to solve the transmission of short- and medium-distance network monitoring signals in buildings, and uses 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 continuous emergence of large and super-large buildings, it is seemingly powerless to use ordinary network switches with actual extension distances of only 80-100 meters for cascading. The increase in the number of switch cascades makes the system network more complicated, which will definitely reduce the stability and reliability of the system and cause significant network delays, which will seriously affect the overall performance of the system and increase the cost of the project and the difficulty of construction. Therefore, many people consider simply introducing optical fibers into the building's internal network, but on the one hand, optical fibers are not convenient for wiring, on the other hand, welding of optical fiber connectors requires professional equipment and professional technicians. The construction is difficult and the cost is high. After all, it is not the most ideal solution.
In view of the difficulties encountered in the current network high-definition video surveillance new construction projects and the increasing number of analog surveillance upgrade network surveillance and transformation projects in network deployment, Shenzhen Utop Technology Co., Ltd. has successively launched POE and EOC product solutions. The engineering design and construction of the network high-definition video surveillance transmission system provide more innovative solutions and options:
1. POE will pass the power and network together
As mentioned above, the traditional network monitoring and transmission scheme, especially in the range of 1000 meters, mainly has the problems that the equipment extension distance does not match the actual engineering requirements, and the complicated network equipment such as power supply and switching is not conducive to construction and maintenance. Youtepu recommends that you select a 250-meter or 100-meter POE network switch to match the medium and short-distance transmission requirements in the building according to the actual situation, and use a POE network fiber transceiver for outdoor ultra-long-distance transmission combination, so that it can be completely Meet the requirements of the new project of modern network high-definition video surveillance for network bandwidth and transmission distance. Because the network switch and network fiber transceiver developed by Youtepu using POE technology can extend the high-speed network signal, it can also provide stable DC power for network equipment such as network cameras and IP phones with POE receiving function at the front end. In engineering design, it is no longer necessary to consider power supply wiring for the front-end camera, reduce cable use, and improve power safety. In addition, Utop's 250-meter long-distance POE network switch has a transmission distance greatly exceeding that of ordinary network switches. In engineering applications, it can reduce the number of cascade installation of switches. The cost and difficulty of construction and maintenance of the project are greatly reduced The overall performance is also more stable and reliable.
