PoE technology stands for Power over the Internet. It means that instead of using two wires (the usual twisted pair for data transmission and a power cord), you can use a simple Internet wire that will be responsible for both data transmission and electricity supply to devices. This technology greatly simplifies the connection of IP cameras, IP phones, access points, and other network devices, and just greatly helps in a situation where there is no outlet nearby.
Connecting devices via PoE is safer since the twisted pair power supply is stable and does not depend on interference in the 220V network. And with the help of PoE, it is very easy to provide all devices on the network with guaranteed power. To do this, you just need to power the basic network hub from the UPS.
PoE provides centralized management and control of all network devices: switching on/off each individual device (including automatic), keeping records of the electricity consumed by each device. The interface of PoE hubs also allows you to determine the operating mode of individual devices and detect breakdowns on time.
The PoE connection looks aesthetically more perfect — fewer sockets, fewer wires.
PoE injector has the following advantages:
The TL-PoE150S compact Gigabit PoE injector complies with the IEEE802.3af standard. Designed to supply power to a network device without a switch if there is no access to the 220 V network. Works with all PoE and PD-compatible devices. Automatic selection of the normal or cross twisted pair operation mode is available thanks to Auto MDI/MDIX support. The power supply is in 10Base-T, 100Base-TX, and 1000Base-T environments up to 328 feet away.
Plug-and-Play automatically determines the required power requirements.
The PoE Ubiquiti POE-24-12W power supply is suitable for powering routers and other network equipment powered by PoE technology via a twisted pair cable. The adapter is connected to the 220 V network via a power cord, which is provided with a ground connection as protection against electrostatic charges. The output voltage of the power supply (compatible with devices of the Ubiquiti brand) is 24 V, the current is 0.5 A.
Two bright LEDs are located on the front panel of the PoE Ubiquiti POE-24-12W power adapter. One of them is an indicator of the Ethernet connection to the LAN port, and the other informs that the adapter is connected to the power supply. The device can be placed on the wall using the metal bracket included in the kit.
The injector, which operates on the technology of Gigabit Power over Ethernet TrendNet TPE-111GI, allows you to combine power supply with the transmission of digital signals over a Gigabit network. Connect this device to a switch that does not support PoE technology, and run a Gigabit PoE cable up to 328 feet away to connect most PoE devices to the network. There is no need to purchase a PoE switch. It is enough to use the existing switch sockets that do not support PoE technology and connect PoE devices.
Save on installation and equipment by installing TRENDnet access points and IP cameras in remote locations. There is no need to install PoE devices near a power outlet. This compact device protects valuable network equipment by providing short-circuit protection. You can quickly create and integrate a network with your devices and devices, providing Gigabit-level speed.
The Linksys LACPI30-EU PoE injector is designed to provide power via an Ethernet cable using PoE technology to devices installed away from power outlets.
When choosing an installation location for devices such as access points, IP phones, or IP cameras, there is often a problem of distance from electrical outlets. Laying new electrical wiring is not the most rational and quite expensive option. The Linksys LACPI30-EU PoE injector will provide power up to 30W for such equipment at a distance of 328 feet from the source using only a standard Cat5 cable.
The LACPI30 is an extremely easy-to-use device. Moreover, a wide range of options for installation (wall, desktop, floor) provides additional convenience for the user.
Linksys products are high-quality devices made of durable certified materials and work reliably for many years.
Support PoE distance up to 820 feet will allow deploying a network using a network cable where there is no possibility to connect power or no access to an outlet, but you need to configure the APS, IP surveillance, IP telephony, etc.
There is no need to worry about long tangled cables or too much distance between devices and electrical outlets. Smart energy-saving technology allows you to reduce power consumption by up to 70%, thus creating an environmentally friendly environment for your solutions.
Besides, 6kV lightning protection ensures maximum safety and stable energy saving when active for 100,000 hours. With support for IEEE 802.3 af/at PoE power over a single port, the TEF1105P can be compatible with most devices that require high power (up to 30 W).
The switch can also automatically detect connected devices and provide them with power, thereby protecting the system from overload.
Thanks to the well-thought-out architecture of the switch and the ability to transfer data at speeds up to 1 Gbit/second, the device on all ports provides high packet transfer rates and fast file filtering at maximum throughput.
Up to 4 HD IP cameras can be connected at the same time. Data flow control in full-duplex mode and reverse flow control for half-duplex mode allows you to avoid congestion and ensure high-quality data transmission, which ensures the reliability of the switch.
The all-metal housing makes the TEF1105P switch an ideal choice. The unique cooling system guarantees a long service life of the equipment.
As we can see, PoE is quite simple and safe. And in some cases, it can significantly simplify the implementation of a distributed system based on an Ethernet network and reduce its cost. However, when using it, you should spend more time planning the system. You should also choose the right equipment according to the required data transfer rates, cables used, power consumption, and so on.
