Friends who have just come into contact with PoE switches may not know how to choose and use them correctly. Say a few personal experiences for reference only.
There are many types of PoE switches, from Gigabit to Gigabit, to Gigabit, non-network management and network management, as well as a variety of different port numbers, as well as big brands, medium brands, and low-end brands. , so which one is suitable for you needs comprehensive consideration.
For example, there is a monitoring project. It takes about 300 cameras. Each camera has 2 million pixels and the power is 10W. If you use PoE, how do you choose a PoE switch?
Resolution: There are more than 300 cameras, which need to be cascaded. That is, PoE switches and switches are respectively selected. The PoE switch is used as the access layer. Because the camera power is a single 10W, af or at standard PoE switches are available (current PoE switches basically support both standards simultaneously, and the power supply is an adaptive standard). 200 million pixel camera stream 8 trillion, access layer PoE switches can use 8 or 16-port mixed hybrid PoE switches, the convergence layer uses 24 Gigabit Ethernet switches, the core layer of 24 10-Gigabit Ethernet switches . The aggregation layer and the core layer switch have the management function.
Here to emphasize the PoE switch, select each PoE switch can be fully loaded with power, that is, if it is 8-port, you can connect 8 cameras at the same time. In addition, personal advice, do not blindly choose the big brands, in fact, in the engineering mid-end brands more cost-effective.
After selecting a PoE switch, it is relatively simple to use, because no additional power wiring is required. After the PoE switch is connected to the camera through the network cable, the PoE switch can be powered on.
Pay attention to the transmission distance in the process of not exceeding 100 meters. In addition, try to select a PoE switch with a large power supply, and contact the PoE switch of CCIT. The power supply power is good, and the terminal brand price may be more acceptable.
