PoE (Power over Ethernet) technology has earned itself great reputations by improving network agility and scalability in an efficient way. While capable of delivering power and data simultaneously on twisted pair Ethernet cabling, PoE has also gained a universal acceptance in applications including IP camera, VoIP phone, wireless access point and video surveillance system. Various styles of PoE devices exist, such as Gigabit PoE switch, PoE injector and PoE splitter and PoE adapter. Here we will focus on addressing basics of PoE injector and how we can benefit from it.
What Is a PoE Injector?
A PoE injector, or midspan, supports Gigabit speeds while powering compliant devices over a single cable (Cat5e/Cat6/Cat6a). The injector adds power (from the external power supply) to data that is coming from a non-PoE switch to “endspan” (IP cameras, wireless access points and LED lighting). PoE injector is perfect for low power devices that need to be set up in locations where a power outlet is unavailable. It thus enables more flexibility by offering access to install devices in hard-to-reach areas, with a minimal impact on existing structures and budget. The video below introduces the basics of PoE injector.
The following are some distinct features of PoE injector:
And we could benefit from using PoE injector in these ways:
How to Use a PoE Injector?
PoE injector excels in sending data while providing PoE to standard-based PoE and PoE+ compliant devices. If you have a non-PoE switch, a PoE injector should be used to power devices like network access points. Here we illustrate the steps for powering IP camera (it could be other PoE enabled devices) with a PoE injector and a non-PoE network switch, all you need is IP cameras, PoE injectors (depends on the number of powered IP cameras), standard network switch and Cat5e, Cat6 or Cat6a Ethernet cable.
1. Test all equipment to ensure the IP camera, PoE injector and management of the camera is working. Make all video and network configurations before mounting the IP camera.
2. Plug the Ethernet cable into the PoE injector’s Power/Data port and into IP camera’s PoE port.
3. Mount your IP camera in the place where adequate light is available so it could capture a clear image on the screen.
4. Plug another Ethernet cable to connect injector’s Data port and the Ethernet switch.
5. Plug injector power cord into a local AC electrical outlet.
Considerations for Buying PoE Injectors
So what makes the right PoE injector? You need to consider these three aspects before making the choice.
Small as it might be, PoE injector greatly enhances network flexibility and scalability by remotely powering PoE devices at points where no power outlet is available. And it also fixes the problem to connect non-PoE Ethernet switch to PoE enabled devices. FS provides simple to use and robust Gigabit PoE injectors for Ethernet PoE power supply and data communication. For more information, just reach us via firstname.lastname@example.org.
