6.1.4 POE Mode Installation
What is POE (Power Over Ethernet)
Power over Ethernet (POE) is a technology that lets network cables carry electrical
power.
For example, a digital security camera normally requires two connections to be made
when it is installed:
A network connection, in order to be able to communicate with video recording and
display equipment.
A power connection, to deliver the electrical power the camera needs to operate.
However, if the camera is POE-enabled, only the network connection needs to be
made, as it will receive its electrical power from this cable as well.
Why Use PoE?
Specifying Power over Ethernet brings many advantages to an installation:
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.
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.
Safety - POE delivery is intelligent, and designed to protect network equipment from
overload, underpowering, or incorrect installation.
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.
Scalability - having power available on the network means that installation and
