Everything has become interconnected with the advancement of different technologies. These devices can transfer large amounts of data among each other, resulting in greater connectivity. This is why the network connection plays a significant role in this process. As a standard for network devices, Power over Ethernet was created.

Dual mode power and data transmission is possible with Power over Ethernet (PoE). This eliminates the need to have a separate power and data cable. This technology is becoming increasingly popular so it’s a good idea to have some knowledge about it. This article will explain PoE in greater detail.

Power over Ethernet Technology (PoE).

The Power over Ethernet technology was created to support wireless devices and connect to a wired network. This technology is used to establish connections between LAN networks. An Ethernet data cable is used to make this connection. This cable transmits data and also powers connected devices.

PoE reduces costs and simplifies wiring. This technology can be used with various devices such as CCTV cameras and VoIP phones. Let’s now discuss how PoE works.


It is easy to use PoE technology. The electricity must pass through the Ethernet cable and be available to the device’s outlet. There are many wire configurations in the core of the cable. Data transmission speeds are determined by the different types of cables. To avoid signal interference, the power carrying wire must be kept apart.

The device that connects to the cable may be PoE-enabled or not. A PoE-enabled device does not require any external modifications to be compatible with the Ethernet cable. An external device, called a “picker”, or “tap”, can be used to disconnect the cable’s power if the device isn’t compatible with PoE.

Types of PoE and Their Maximum Wattage Output

Since its inception, the PoE has undergone constant upgrades. Each type has more power, data and connectivity than their predecessors. Below are detailed descriptions of each type.

  • Type 1 (or standard PoE): This is the earliest version of PoE at the time it was launched. This type is part of the IEEE 802.3af standard rating. It can supply 15.4W power to the connected device. Two pairs allow you to divide the power. It was compatible to the Cat3 cables.
  • Type 2 (or PoE+): The type 2 PoE uses IEEE 802.3at as its ethernet standard. The PoE++ can output 30W of power. It can also split power, just like the type 1 PoE. It is compatible with older generation PoE devices due to its backward compatibility. It was compatible to the Cat5 cables.
  • Type 3 (or PoE++):Type 3 POE comes with an upgraded 4-pair configuration. It is ideal for high-performance applications that require fast data transfer speeds. It follows the IEEE 802.3bt standard. The ports’ maximum power output was also increased from 50W to 60W. This PoE version is compatible with ethernet cables Cat5 and above.
  • Type 4 (High-Power PoE):Type 4 refers to the latest version of PoE. Because of its high power performance, it is also known as the high-power PoE. It can manage smart connectivity applications at a greater scale thanks to the IEEE 802.3bt standards. The type 4 PoE can output 100W at its ports. It works with all ethernet types (cat5 through cat8 and higher).

PoE Power Components

Because different PoE types have different power outputs it becomes crucial to control the power going to connected devices. Two components are included in the PoEs that manage power and network connections.

1. Injector

An PoE Injector, which is a basic device, is connected to a power source. You can also connect ethernet cables to it via the inlet ports. Another end of the injector contains outlets that allow ethernet cables to be connected to other devices. The injector can convert an ordinary ethernet cable (not power) into a powered cable. The output is compatible with both PoE compatible devices and non-compatible PoE devices.

2. Splitter

The PoE splitter works opposite to a PoE injector. It produces two outputs. The one that is used for data and the other for power. Splitter input is a powered Ethernet cable, which contains both power and data. The splitter then divides the cable into two outputs. The unpowered Ethernet cable is made while the power cable is used to carry only power. The power cable can then be used to power devices that do not support PoE. This power cable is used to power remote devices.

The pros and cons of PoE for Smart Homes

PoE can be successfully integrated with IoT devices and smart home apps. It is capable of synchronizing with smart homes and enhancing the automation process. The most recent generation has enough power. Below are some advantages and disadvantages to PoE technology for smart home. This will help you decide if this technology is right for you.


  • PoE technology is easy to set up and eliminates the need of power outlets
  • It can be connected to almost any smart device within range and allows for control over them
  • It can transmit data and power so the cost of an external power cord is reduced
  • PoE is embedded with safety features and senses power fluctuations to automatically stop the system from any danger.
  • The current generation of PoE can be used with Cat5 and higher ethernet cables to achieve data transmission speeds of 5Gbps.
  • PoE has a higher encryption level and protects data from theft.


  • PoE is centered so any failure will result in the loss of the entire network.
  • To increase the range of the power transmission, it is necessary to extend its range.
  • PoE older versions are not appropriate for high-power applications
  • Professional installation is required for all ethernet cables throughout the house
  • Security may be compromised in the event of a network failure.

PoE Devices for Home

You now have enough information on Power over Ethernet devices to make the decision easy for your application. We have chosen the best PoE devices to deliver the desired output, despite the fact that there are many pitons on the market.

1. TP-Link

TP-Link is a well-known manufacturer of network devices around the globe. Its product line is constantly evolving thanks to consumer feedback.

The TL-PoE150S model by TP-Link is one the most popular PoE injectors on the market. It can be used with many devices, including cameras. This option offers a maximum bandwidth of 1000Mb. This option has a 100 meter range and can therefore be used to power smart homes. The maximum output is 15.4W, according to IEEE 802.3af.

2. Netgear

Netgear, a brand that focuses primarily on smart home-oriented networking devices, is one of the most recognized brands. It is an innovative brand that uses new technologies to create its products.

Netgear’s GS305P model offers excellent connectivity. It boasts Ethernet ports that can transmit data at speeds of up to 5Gbps. This model has 4 power ports and offers 55W combined power. It is compliant with IEEE802.3az standards and has high energy efficiency. It also features a metallic structure and a fanless design, which makes it silent.

PoE Application for Smart Homes

As it is compatible with smart homes, the number of PoE-connected devices keeps growing. Here are some PoE devices that can be used in smart homes. This will help you understand how PoE works around us, and it will adapt to each application.

  • Security Cameras These cameras have been designed to work with PoE technology. This allows remote access to these cameras. Video surveillance is therefore enhanced by PoE.
  • VoIP Phones:Voice Over Internet Protocol (VoIP), phones can be used to make voice calls. They use PoE technology to make voice calls instead of calling regular via analog lines.
  • Motorized Shades and Blinds: Smart home windows have blinds and shades that can be controlled by PoE. You can do this by pairing the shades and blinds with smart home networks, and selecting triggers. These triggers automatically open and close shades when there is sunlight or a certain time of day.
  • Speakers The speakers can also be paired to PoE. The speakers and the ethernet cable connect to each other. This allows the speakers to be installed anywhere, without needing to plug into a power outlet. It also allows for stable data transfer and streaming music with no lag.
  • DoorbellsPoE doorsbells are not the same as regular doorbells. The wires are replaced with an Ethernet cable and they do not use regular wiring. This allows the bell to be powered and connects to the central network.
