IEEE802.3af Active Wall-mounted Poe Injector For Wireless access point

What is a Power over Ethernet (PoE) injector?
Let’s start with a definition. PC Magazine defines the PoE injector as follows:

“A device that adds power to an Ethernet cable for Power over Ethernet (PoE) equipment. Although Ethernet switches are available with PoE capability, millions of regular “non-PoE” switches are in use and continue to be installed.”

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.

How does a PoE injector work?
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.
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.

Data In port
Let’s use the example of an IP security camera. The Data In port connects the security camera to the local network, the NVR camera port, or a network switch. If this port is not connected to the security camera, the local network is unreachable.

PoE/Data Out port
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.
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.
