Your Guide to PoE
Power over Ethernet (PoE) is fast becoming a preferred
option because of its reduced total cost of ownership,
enhanced operability, and easy integration with power
backup systems. It’s especially valuable when installing
surveillance cameras, adding wireless access points
(WAPs) that allow easy access to your network or the
Internet, and implementing access control devices such
as card readers, automatic door locks and automatic
gates, with or without biometrics.
PoE makes applications like these easier and more
affordable. But how do you get started?
This guide can help. It provides the basic knowledge
you need about PoE, no matter what your role is in a
PoE project. If you install PoE-based solutions, this guide
will help you to design and configure the most effective
solutions for your customers. If you’re an end user of
power equipment, you’ll find this guide can help you
make the most informed purchase decisions when
considering a PoE solution.
PoE Background
PoE was designed for the information technology
market and initially focused on IP phones (devices that
use Voice over IP, or VoIP, technology), along with IP
cameras, WAPs, and access control devices. PoE is
also working its way into industrial applications,
including process control.
Initially, the only cabling topology supported by PoE
was a star topology. Now there is advanced managed
power source equipment that can be configured in a
ring or mesh topology to provide signal redundancy.
These installations can use cabling that is Category 5e
or higher.
