Advantages of POE switches in weak current construction

First, the type of PoE switch

The standard PoE switch is mainly equipped with a power adapter with a DC48V-56V voltage as a parameter standard, with a PD device camera, and directly connected to the network cable for data exchange and power supply.

Non-standard PoE switches, from the simple output voltage parameters, most of the power adapters on the market are from the DC15V-24V voltage range. The connected cameras are mainly based on the step-down PoE splitter for data exchange and power supply.

When a non-standard POE is powered, it is easy to damage the terminal device because of the lack of related protocols. Therefore, when selecting a POE switch device, it is recommended to know in detail whether the switch supplies power to the standard POE.

Second, the advantages of PoE switches in use

1. Reduced construction cost: PoE network cameras do not need to be connected to another power supply. Only one network cable needs to be arranged to provide power and transmit data signals, which can save expensive power lines and sockets, and save the need to lay power lines. Labor costs, construction is very simple and convenient.

2. Construction safety is strong: Many weak electric engineering companies do not have strong electric construction personnel. If they are risky to construct, they may cause safety accidents. PoE power supply can be easily solved, and there is no need to find an electrician.

3. The signal is not disturbed: because the network cable is easily interfered by strong magnetic fields, PoE power supply can make the signal undisturbed because of the DC power supply, and the picture is clearer.

4. Environmental protection and energy saving: When the network camera adopts PoE power supply, the power receiving module has power recognition function, which will not waste energy and effectively save energy.

5. Low maintenance cost: easy maintenance, no need to maintain the power adapter, power cord, power outlet, etc.

6. Stable performance: Less wiring and more stable performance.

7. Beautiful and elegant installation: The front-end installation is simple, and it is not necessary to deal with the power adapter and set up a waterproof box and other devices that affect the appearance.

8. High safety factor: Powered by PoE, there is no strong power at the front end, the system is safe, and there will be no accidents due to power problems. Especially in places with high safety requirements, outdoor open air and humid environment, the advantages are more obvious.

Third, the advantages of the switch

1. At present, the product technology of the switch is very mature, and many people do not know that the design scheme of the manufacturer is basically the same. In simple terms, the core chip scheme can be realized. For example, MediaTek, China's HiSilicon and Spreadtrum, Broadcom, Huawei, etc., there are many other domestic brands, and each brand also has many series of products, then these options also determine the quality and stability of the products, so everyone will It is found that there are very cheap products on the market, and there are also very high prices. Its application and performance, parameters and functions are also different.

2. Optical path technology PoE switch is also a mature solution to develop and produce PoE switch products for network monitoring industry. The commonly used 4-port and 8-port and 16-port and 24-port products on the market are mainly power supply and data transmission. Switch data exchange technology is OK, and another power supply can not be ignored. For example, everyone knows that desktop computer products, if the power supply configuration is insufficient, the stability is low, the ripple and output current are not pure, which will affect the computer use effect. It is common that the computer responds slowly, generates a large amount of heat, and easily causes the computer. The main components are damaged and so on. Then the principle of the switch is the same.

3. Therefore, the advantages and disadvantages of optical road technology in the research and development of power supply can greatly ensure the safety and stability of the power supply. In combination with the mature technology of the switch, the PoE switch products will not increase the data loss when the power supply is provided. The connection data is unstable, and the power is repeatedly activated, resulting in a decrease in product life and normal function use.
