2. Preface
Power over Ethernet (PoE) has found widespread applications in markets
such
as VoIP telephony, wireless LANs, IP video security and access control, since
its standardisation in 2003. It is
gaining popularity across the
spectrum of IP surveillance and
access control applications.
But what is PoE?
The follows will analyze it step
by step.

5. 1Basic Concept of PoE

6. ➢ Power over Ethernet (PoE) is a technology that supplies power to video surveillance cameras
through an Ethernet cord. It allows network cables to carry electrical power to the surveillance
cameras and at the same time gives each camera direct network access. It simplifies the
installation of digital security cameras because you will not need a power supply socket for
each camera since the network cables carry electrical power.
Basic Concept of PoE
➢ PoE is a technology that was initially developed in 2000 by Cisco for VoIP
phone systems to reduce noise, and has since then emerged as a simple
solution when installing networked video surveillance systems. The wider
application of PoE to IP cameras and wireless systems has resulted to the
implementation of standards that foster uniformity among PoE device
manufacturers. With PoE, installation of multiple surveillance cameras for
your security network requires only one cable for the PoE switch and all of
the security cameras, using a single power supply.

7. ➢ PoE is defined across a single network link which includes three basic components. The first
component is an equipment delivering power to the cable (often referred to as a PSE, which
stands for power sourcing equipment). The second component is a device receiving power
from the cable (also known as a powered device, or PD). The third is the cable itself.
➢ Typical PDs include IP cameras, wireless access points, and the PSE would normally be a PoE
switch or a midspan power injector, patched in to add PoE capability to a non-PoE network
switch channel or similar. These two configurations are shown in the following picture. Note:
this part will be described more clearly later in this article.

9. 2Advantages of PoE

10. ➢Time and cost savings
by reducing the time and
expense of having electrical
power cabling
installed. Network cables do
not require a qualified
electrician to fit them, and can
be located anywhere.
Advantages of PoE

11. ➢Flexibility
without being tethered
to an electrical outlet,
devices such as IP
cameras and wireless
access points can be
located wherever they
are needed most, and
repositioned easily if
required.
Advantages of PoE

12. ➢Safety
POE delivery is intelligent, and designed to protect network equipment from
overload, underpowering, or incorrect installation.
Advantages of PoE

13. ➢Reliability
POE power comes from a central and universally compatible source,
rather than a collection of distributed wall adapters. It can be backed-up
by an uninterruptible power supply, or controlled to easily disable or
reset devices.
Advantages of PoE
√

14. ➢Scalability
having power available on the
network means that
installation and distribution of
network connections is simple
and effective.
Advantages of PoE

15. 3Applications of PoE

16. ➢VoIP phones
the original POE
application. Using POE means
phones have a single
connection to a wall socket, and
can be remotely powered down,
just like with the older analog
systems.
Applications of PoE

17. ➢ IP cameras
POE is now ubiquitous on
networked surveillance
cameras, where it enables fast
deployment and easy
repositioning.
Applications of PoE

18. ➢ Wireless
Wifi APs and RFID readers are
commonly PoE-compatible, to
allow remote location away
from AC outlets, and relocation
following site surveys.
Applications of PoE

19. 4How PoE Works

20. ➢ PoE is designed to operate over
standard network cable: Cat 3,
Cat 5, Cat 5e or Cat 6 (often
collectively referred to as Cat 5),
using conventional RJ45
connectors.
How PoE Works
➢ The principles of carrying
electrical power over Cat5 are
no difference to those of other
power distribution systems.

21. ➢ The arrangement and connection to the cabling used for PoE also
differ slightly from conventional power wiring, in order to work around
the existing standard for Ethernet data. Cat 5 network cables contain
a bundle of eight wires, arranged as four twisted pairs shown in the
following picture. In the most common type of Ethernet, 100BASE-T
or Fast Ethernet, only two of the four pairs are used to carry data;
each pair carrying a signal in one direction. These are known as the
data pairs, and the remaining two are unused and are referred to as
the spare pairs.
How PoE Works

22. How PoE Works

23. Although each data signal can be carried within a single pair, PoE treats each pair of wires
as a single conductor (a reason
for this is that using both wires
haves the overall resistance).
As electrical current must flow
in a loop, two pairs are required
to allow power to be carried by
the cable, and either the data
or spare pairs can be used for
this. The PD must be able to
accept power from whichever
pairs the PSE delivers it to.
How PoE Works

24. 5How to Connect PoE

25. A PoE switch (such as WI-PS205,WI-PS210,WI-PS128G) is a network switch
that has power over Ethernet injection built-in. Simply connect other
network devices to the switch as normal,
and then the PoE switch will detect whether
they are PoE compatible and enable power
automatically. PoE switch is available to suit
all applications, from low-cost unmanaged
switches with a few ports, up to complex
multi-port rack-mounted units with
sophisticated management.

32. Wi-Tek 250meters Long-Range PoE tech
Due to the complex monitoring environment, when making cabling and networking ，
it very often to encounter the problem of inadequate network transmission distance,
the distance of each camera terminal to the monitoring center is different, some
only a few meters, some hundred meters, while others are more than kilometers. WI-
