Introduction to the five advantages of POE switches


Before understanding PoE switches, we must first understand what PoE is.

PoE is a power supply over Ethernet technology. It is a method of remotely supplying power to connected network devices (such as Wireless LAN AP, IP Phone, Bluetooth AP, IP Camera, etc.) on a standard Ethernet data cable, eliminating The problem of installing a separate power supply device on an IP network terminal device makes it unnecessary to deploy a separate power supply system for the device at the use site, which can greatly reduce the wiring and management costs of deploying terminal devices and promote the development of related fields.

The PoE switch is based on the traditional Ethernet switch, with the addition of PoE function inside, so that the switch not only has the function of data exchange, but also can transmit power through the network cable at the same time. This is the network power supply switch. It can be distinguished from ordinary switches in appearance. PoE switches have the word “PoE” on the front of the panel, indicating that they have PoE functions, while ordinary switches do not.

1. More secure

We all know that 220V voltage is very dangerous. The power supply cables are often damaged. This is very dangerous, especially in thunderstorms. Once the power receiving equipment is damaged, the phenomenon of leakage is inevitable. The use of PoE switches is much safer. First of all, there is no need to pull the power supply, and it provides a safe voltage of 48V.

2. More convenient

Before the prevalence of PoE technology, 220V power sockets were used for power supply. This construction method is relatively rigid, because not every place can be powered or installed, so the best camera position is often hindered by various factors The location has to be changed, which results in a large number of blind spots for monitoring. After PoE technology matures, these can be resolved. After all, the network cable can also be powered by PoE.

3. More flexible

The traditional wiring method will affect the networking of the monitoring system, resulting in the inability to install monitoring in some places that are not suitable for wiring. However, if the PoE switch is used for power supply, it is not limited by time, location and environment, and the networking method will also A lot of flexibility, the camera can be installed arbitrarily.

4. More energy saving

The traditional 220V power supply method requires a wide range of wiring. In the transmission process, the loss is quite large. The longer the distance, the greater the loss. The latest PoE technology uses low-carbon and environmentally friendly technology with very little loss. From the perspective of it, energy saving and environmental protection can be achieved.

5. More beautiful

Because the POE technology makes the network and electricity into one, there is no need to wire and install sockets everywhere, which makes the monitoring place look more concise and generous. The POE power supply is powered by a network cable, that is, the network cable that transmits data can also transmit power , This not only simplifies the construction process, reduces installation costs, and is safer. Among them, POE switches are widely loved by security engineers for their high performance, simple and convenient use, simple management, convenient networking, and low construction cost.
