What kind of PoE switch is more suitable for remote monitoring?
PoE switch is a kind of network power supply, which can be supplied directly to the power supply network equipment, so that they operate normally.
There are many types of PoE switch, take Hong Ruiguangxiang, PoE switch‘s dozens of products, from 4 to 24 port port simple, from 100m to Gigabit, with network management, also has no network, how to choose suitable for their own monitoring?
In the traditional network monitoring project, the centralized power supply is used to monitor the power supply of the camera, in addition to the high cost, complex construction, and the wiring, power supply risk, power supply and other restrictions.
PoE power supply is an inevitable trend of security power supply, PoE switch and the network camera only need to connect an ordinary cable, you can transmit data and power supply.
Choose PoE switch will not ignore the brand, you need to look at the power supply standards, power supply, port number, transmission rate, the overall performance and other factors.
PoE switch power supply standards are AF and at standard, the former provides 15.4W power supply, which provides 30W power supply, according to the flashlight equipment to choose the appropriate standard PoE switch. Also depends on the total power supply, otherwise the connection of the electrical equipment, and may not be able to afford.
The number and rate of PoE switch is the most important index to choose, and it is necessary to choose the appropriate interface rate and the number of interfaces to ensure the video traffic is not blocked and real-time transmission.
In general, there are two main parts of video stream and the sub stream, when the PoE switch interface rate selection is the most important to consider the total stream uplink port can carry all the camera. For example, 20 road 2 million pixel camera, the main stream is 20*4M=80M, sub stream 20*0.5M=10M, the total bandwidth of 90M. Taking into account the bursty traffic and bandwidth and other data terminal, recommended Gigabit uplink switch.
In addition to taking into account the late expansion problem, it is recommended to choose a large interface rate PoE switch.
Choose Poe switch to find the brand manufacturer Hong Ruiguangxiang
