PoE InjectorUbiquiti

Setting this up usually requires three devices: 1) a connection to the network (E.g., a router or a switch), 2) the PD, and 3) the PoE injector itself.

These devices connect a wireless access point (WAP), PoE lighting, IP camera, or any IEEE 802.3af, IEEE 802.3at, and IEEE 802.3bt-powered device (PD) to a network switch. Power is then “injected” into an Ethernet cable. Typically, a PoE injector converts AC to DC to power these low-voltage PoE devices.

Depending upon the output power voltage a PoE injector supplies, it is put into one of three types: 12V, 24V, or 48V. The voltage of a PoE injector must be taken into account as its voltage and the voltage standard of the PoE device must be compatible.

Conforms to the PoE standard of IEEE 802.3af, IEEE 802.3at, or IEEE 802.3bt is considered to use active PoE. During the initial handshake, if the PoE injector does not receive the proper acknowledgment, it will not power up, ensuring the device’s safety. The typical 802.3at/af/bt PoE voltage is 44 to 57 volts (V) DC.

Versa Technology has a line of high-quality PoE injectors that will enable you to couple non-PoE power sourcing equipment (PSE) with PoE PDs.

A PoE injector usually has two RJ45 ports, one labeled Data In and one labeled PoE/Data Out. Following is an overview of what each of these ports does.

As stated above, these (also called midspan or PoE adapter) are used to make a non-PoE LAN switch port work with PoE devices. A PoE injector is ideal for low-power devices that need to be installed in hard-to-reach places where there are no power outlets available. This affords power with no impact on existing building structures at a minimal cost.

This port has two functions: 1) It delivers power to the IP security camera, and 2) it completes the network, so data is transmitted successfully. If this port is not connected to the security camera, it will not power up and will not connect to the NVR/network.

In addition, they can also be typed by the number of ports they have (e.g., one-port PoE injectors, eight-port PoE injectors, etc.)

Power over Ethernet (PoE) delivers both power and data concurrently via twisted pair Ethernet cabling. This technology improves network agility and scalability in efficient and cost-effective ways. There are several types of PoE devices, for example, the PoE switch, PoE splitter, PoE injector, etc. This article focuses on the PoE injector: What is it? What does it work? Are there different types? How is it installed?

Adopts PoE technology that does not conform to the 802.3at/af/bt standard is considered to use passive PoE. Generally, passive PoE devices run on 18 to 48 volts. It is important to note that it may likely cause permanent electrical damage to the device if the wrong voltage is connected.
