1PORT Poe Injector Ac Input 802.3AF and Cisco Supported Review

(More customer reviews)Although Power over Ethernet (PoE) was once only a term used in IT departments of businesses, this technology is being implemented in more and more consumer electronics and is slowly becoming known in homes with a computer network as well.The concept is quite simple; running data and low voltage power across a single cable.While this may not immediately sound very interesting or important, PoE allows the installation of electronic, networked devices, without the need for an AC power source at the installation site.This is especially useful for products like network security cameras, VoIP telephones, and Wi-Fi amplifiers.There are two primary types of PoE power sourcing equipment (PSE).PoE endspans, which are Ethernet switches with built-in transmission circuitry, and PoE midspans, which are Power over Ethernet products that stand between a regular Ethernet switch and the device needing power.This review is for the PD-3001/AC single port PoE Injector, made by PowerDsine (now owned by Microsemi), which is a PoE midspan device.

I recently found the need to add PoE capabilities to my home network when I decided to install some new network security cameras around the house.I wanted ceiling mounted dome cameras, and most of the units I found were PoE cameras.I knew about PoE technology but had never had any direct involvement with it.I quickly decided that I did not wish to purchase an expensive PoE network switch for my home, so I needed to find a low cost alternative.That is when I found the PowerDsine 3001/AC PoE Injector.This device allows me to run a data cable from my Ethernet switch to the PoE injector, the PoE injector plugs into an AC wall outlet, and then another Ethernet cable comes out of the injector and runs to my PoE camera.This way I only have a single cable running to each of my cameras, rather than having to run separate power and data cables.

The important thing to know, when purchasing a PoE product, is to make sure that it complies with the IEEE 802.3af power distribution standard, from the Institute of Electrical and Electronic Engineers (IEEE).IEEE802.3af provides for 48 VDC over 2 of the 4 available pairs on Cat 3 and Cat 5 network cables, with a maximum current of 400 mA, for a maximum load power of 15.4W.You shouldn't have to worry much about the actual specifications as long as you make sure that both PoE devices on each end comply with the IEEE 802.3af standard.It is usually noted on the product itself or in the product specifications.And speaking of specifications, here are the technical specs. of the PowerDsine PD-3001/AC PoE Injector:
