10/100/1000Mbps 10 Port Ethernet POE switch 24V/48V IEEE802.3af/at
for IP camera
How does POE work?
Network cables, such as Cat 5e and Cat 6, comprise eight wires
arranged as four twisted pairs. In 10 and 100BASE-T Ethernet, two of these pairs are used for
sending information, and these are known as the data pairs. The other two pairs are unused and are referred to as the spare pairs (Gigabit Ethernet uses all four pairs).
Because electrical currents flow in a loop, two conductors are
required to deliver power over a cable. POE treats each pair as a
single conductor, and can use either the two data pairs or the two
spare pairs to carry electrical current.
Power over Ethernet work
Power over Ethernet is injected onto the cable at a voltage between
44 and 57 volts DC, and typically 48 volts is used. This relatively
high voltage allows efficient power transfer along the cable, while
still being low enough to be regarded as safe.
This voltage is safe for users, but it can still damage equipment
that has not been designed to receive POE. Therefore, before a POE
switch or midspan (known as a PSE, for power sourcing equipment) can enable power to a connected IP camera or other equipment
(known as a PD, for powered device), it must perform a signature detection process.
Signature detection
Signature detection uses a lower voltage to detect a characteristic
signature of IEEE-compatible PDs (a 25kOhm resistance). Once this
signature has been detected, the PSE knows that higher voltages can
be safely applied.
10 ports POE ethernet switch
10 ports 10/100/1000M POE Switch is a Gigabit POE Switch,Which is cost-effective provide network
layout need to simplify wireless access point (AP) and IP-based
surveillance cameras network cameras in order to install in
commercial network and home network. The devices far away from
power socket are very suitable for hanging on the wall or ceiling.
PoE eliminates the need for connecting these devices to power
socket. So it make more flexible for those difficult to connect
with AC power socket, and cut down the installation cost. It is
ideal choice for those want to deploy a small commercial network
and home network that use wireless access point (AP) and IP-based
surveillance cameras.
