With the rapid development of information technology, Power over Ethernet (PoE) has no longer been a myth as it has become quite ordinary in offering electric power and transmitting data to various devices at the same time.
What Is Power over Ethernet?
Power over Ethernet(PoE) is a technology that any of several standard or ad-hoc systems can pass electric power along with data on twisted pair Ethernet cabling. This allows a single cable to provide both data connection and electric power to devices such as wireless access points, IP cameras, and VoIP phones. PoE technology ensures the security of existing structured cabling while the operation of existing networks and minimizes the cost.
Generally speaking, a network cable can transmit data and provide power. When installing a network camera and a wireless network device, you can save time deploying power cable.
5 Benefits about PoE
Benefit 1: Electricity Is All Around
Before the prevalence of PoE technology, a large number of 220V power outlets were used, which was very inflexible because not every place was suitable for deploying wires or installing power outlets. For example, if there is a monitoring point, a surveillance camera needs to be installed, but it has to be replaced due to the inconvenience of using electricity.
For example, inside a new hotel, it is necessary to re-deploy the wireless network coverage to install the wireless AP. The traditional power supply method also needs to drill around, so that the construction cost becomes very difficult.
When facing such a situation, you need a UR51 (PoE router).
Benefit 2: Environmentally-Friendly
The traditional 220 volts supply requires a large range of wiring, and the loss is large in the process of transmitting power, especially at a long distance. PoE routers using the latest PoE technology generally adopt low-carbon, environmentally-friendly, and energy-saving technologies, and consume little energy. This is also in line with our current call for energy conservation and environmental protection.
Benefit 3: Flexible
Due to the influence and limitations of traditional wiring, the composition of wireless network coverage and monitoring systems will be relatively rigid, especially in places that are not suitable for wiring. However, PoE is used to supply power and network, regardless of time, location and the environment, thus making the system becomes flexible and the camera can be installed at will.
Benefit 4: Reliable
PoE is typically 48 volts is used, which is high enough for efficient power transfer along the cable and low enough to be safe.
