Be sure to remember to select PoE switches and use points!

If you plan to choose or use PoE switches, these knowledge points must be seen, you can make detours, less trouble.

What do you pay attention to when choosing?

1, do not figure cheap, especially the core thing, this you know

Domestic is a large variety of products flooding the market, PoE switches are no exception. PoE switches on the market, large and small brands are numerous, the price and quality vary greatly. Some initial contact with PoE power supply, think that as long as the PoE switch on the line, good point, bad does not matter, so in order to save costs, often compared to N, select the lowest price.

Not to say cheap, cheap, good goods, but after all, less. Generally speaking, the higher the price of a thing, the hardware, parts, accessories, chips and so on, are high-quality, guaranteed, very low price things, there are many pitfalls and deficiencies. For PoE switches, the price may be too low in the late use of a lot of problems, such as power supply instability, no power supply, after-sales and other issues can not be carried out.

Want to buy quality and cheap, and personally feel that Fengrun PoE switch is OK, perhaps to meet your requirements.

2, try to stay away from non-standard

Most of the PoE switches are standard, and a small number of non-standard ones. The reason for the existence of non-standard is because the cost is low, but because some places can use non-standard. But non - standard PoE switches have potential security problems, such as burning out network devices connected to them. When using a non-standard PoE switch, the voltage of its supply and the voltage of the equipment must be the same.

Standard PoE switches are more secure, and can automatically connect the network devices connected with them. PoE switches will only be powered by PoE devices that support the power supply, so as to ensure the safety of the electrical equipment.

3, choose the right model

The PoE switch model, port number 4, 8, 16, 24, a fast and Gigabit transmission rate, power 60W, 96W, 150W, 250W, 400W, need what port number and port transmission rate, need to choose the right.

Remember: the port transfer rate PoE switch utilization rate at about 40~60%, a network if the theory through fast PoE switch, then select Gigabit switch. In addition, the surveillance camera with infrared light like this, we must consider the infrared lamp power.

Two, what to pay attention to when using?

1, the best network cable, this dry, used, eat the loss of all know.

The quality of the network cable is crucial to the success of the PoE power supply. It is generally recommended to use five types of network cables, over five types of network cables and six types of network cables. The internal material of the cable is also important, do not use any aluminum, copper, aluminum, copper, iron wire, iron wire, etc., the use of pure copper wire is the best.

2, at a distance of 80 meters

The theory of PoE power supply at the distance of 100 meters, but given the market access line quality and the influence of environment, the actual use of the power supply to maintain the distance within 80 meters.

Remind: PoE power supply is only one of the power supply mode of many projects, there are many other ways, each has its own applicability, no matter good or bad, we can choose according to the project requirements and construction difficulties.
