What is the advantage of using a power over Ethernet injector?

A power over Ethernet injector is a device which allows the transfer of both data and power over the same cable system rather than the two cables normally required for this purpose. This type of cable follows the IEEE standards and finds use in numerous modern communication devices some of which are network routers, network webcams, VoIP phones, network time protocol wall clocks, hallway amplifier speakers, mini network switches, wireless access points and network systems such as intercom, paging and public address systems. The use of Ethernet injector in PoE circuitry is highly preferred due to numerous advantages it offers. The advantages of power over Ethernet injector are:

1. Lowering of cost – As instead of 2 cables we are now using a single cable the cost is considerably reduced. While not only this is not possible in normal conditions but under the normal conditions we would be using two cables or the USB connection which has too less speed for most practical uses. There is a further advantage that you need not satisfy the building requirements for running an AC cable.
2. High speed data transfer – Power over Ethernet injector provides extremely fast data transfer facility. The speed attained with this cable can reach to 1GB per second which is the highest data transfer speed reached with any cable.
3. Easy functioning under power outage – In Power over Ethernet injectors, operator has the option of directly connecting the 48 volt powered DC battery array. This is helpful in putting up a infrastructure system for backup in case of power outages. This means that Power over Ethernet ejectors are not affected by the power rationalizing unlike other normal systems.
4. This cable has the advantage over the USB system of power symmetry. While an USB cable has only one sided power transfer i.e. from the female connector to male connector side the Power over Ethernet injector has the freedom of double sided transfer technology due to which power and data can be transferred from either side. This gives the freedom to installation of the cables and outlets even before location for the power source is decided.

Even if your system does not have a PoE injector even then they can convert your system to PoE injector system by installing a DC trap.
