What are the risks or disadvantages of PoE power supply technology in engineering applications?
1. Insufficient power, the receiving end can’t move: 802.3af standard (PoE) output power is less than 15.4W, which is sufficient for general IPC, but for high-power front-end equipment such as dome cameras, the output power cannot reach To request. 2. Risk is too concentrated: Generally spe...Read more -

The safe transmission distance of PoE power supply? What are the suggestions for the choice of network cable?
The safe transmission distance of POE power supply is 100 meters, and it is recommended to use Cat 5e copper network cable. It is possible to transmit DC power with a standard Ethernet cable for a long distance, so why is the transmission distance limited to 100 meters? The fact is that the maxim...Read more -
How to turn an ordinary switch into a PoE switch？
If you want to turn an ordinary switch into a PoE switch, directly assembling an ordinary switch into a PoE switch cannot fully realize power supply and data transmission at the same time. Unless you know the relevant knowledge of the switch well, you can only meet your needs in other ways , Here...Read more -
Can a PoE switch be used as a normal switch?
PoE switch is a new type of multifunctional switch. With the wide application of PoE switch, people have a certain understanding of PoE switch. However, many people think that PoE switches can generate electricity by themselves. This statement is not correct. Generally speaking, PoE switch power ...Read more -
Analysis of the characteristics of the Layer 2 industrial switch
The development of the two-layer switching technology is relatively mature. The two-layer industrial switch is a data link layer device. It can identify the MAC address information in the data packet, forward it according to the MAC address, and record these MAC addresses and corresponding ports ...Read more -
What are the advantages of Layer 3 switches?
The technology of the Layer 3 switch is becoming more and more mature and its applications are becoming more and more extensive. In a certain range, it has more advantages than routers, but there is still a big difference between the three-layer switch and the router. In the local area network, t...Read more
