What do you need to know about PoE injectors?

The typical use of a PoE injector will require 3 devices. The PoE injector itself, A connection to the network, usually a router, or a switch, and the device that requires the PoE injector in this case an IP security camera. The Data In port is used to connect the security camera to the local network.

What kind of power does a Poe camera need?

PoE standard provides up to 15.4 W of DC power. This is the older standard of the two but many cameras will have this as a listed specification still and most of regular IP cameras work on this standard. 802.3at. PoE standard also known as PoE+ or PoE plus, provides up to 25.5 W of power and is backwards compatible with 802.3af devices.

Do you need PoE injector for PTZ cameras?

PoE standard also known as PoE+ or PoE plus, provides up to 25.5 W of power and is backwards compatible with 802.3af devices. The PTZ cameras need a PoE injector that supports this standart (since the PTZ cameras require a lot of power to function properly).

What does the Poe data out port do?

The PoE/ Data out port does two things, it provides power to the camera and also completes the network so data transmission can be complete. Without this port connected the camera will not power up, and will not connect to the NVR/network. How much power can the PoE Injector provide to the IP camera?

Why to use PoE injector?

A PoE injector connects your PoE-enabled network device to a non-PoE LAN switch port. More specifically, a PoE injector can be used to connect a wireless access point, IP phone, network camera or any IEEE 802.3af/at-powered device (PD) to a network switch. Using a PoE injector avoids the need to run AC power lines for your wireless access point, network camera or IP phone, because you use the existing LAN cabling to deliver both DC power as well as data.

Do you need a PoE injector?

If you didn’t want to upgrade your non-PoE enabled network switches, you’d have to use a PoE injector for every single device on the network. Sure, this wouldn’t be an issue if you were setting up a home network with only a few devices – on the other hand, as the network scales and more devices must be added, trying to use PoE injectors to solve the problem would quickly turn into a big jumbled mess of wires.

What are the PoE injector specifications?

Electrical specifications for PoE injectors include inlet type, input voltage, data line pin-out, category 3 (CAT-5) cable pin-out, supply voltage, maximum current, nominal available output power, and nominal output voltage . Input currents may be specified at 110 VDC and 220 VDC, or over 100 – 250 VAC.

What is the difference between a PoE injector and a Poe splitter?

The difference between an injector and a splitter is that a PoE injector sends power to PoE equipment that receives data through existing non-POE switches. A splitter also supplies power, but it does so by splitting the power from the data and feeding it to a separate input that a non-PoE compliant device can use.
