Wifi Soft 8 Port POE Injector

Amazing product, accurate power. Professionally designed, worth money.

The vendor sells other versions if you want a "system" that includes power supply and the injector. This is just the injector, no power supply. This is for those who have custom power requirements. I recommend that you do not order this if you haven't read up on POE and don't understand how to use it. I have found that almost all POE kits that include power supplies, whether passive injectors like this or POE network switches, do not provide enough power to fully populate all ports at full 802.3af at 15.4 watts per port, let alone 802.3at at 25.5 watts per port. This is fine for most systems where average power per port is less than maximum but if you have long-distance IR illuminators that take more power you'll find your cameras dropping out intermittently or even premature power supply failure. To fully power 8 ports of 802.3at you need a 204 watt power supply; 8 ports of 802.3af requires 124 watts. If you look at 8-port POE injectors or switches, almost none have power supplies that can fully support the standard. This is a topic for which Wikipedia is your friend. There's a great article there. For 48v, figure just at a half amp of power supply current per 802.3at port at full power, or 4 amps for one of these injectors. To prevent premature failure, I recommend using a power supply rated for 1 amp per port, or 8 amps for this injector, so that you're operating at 50% capacity over time, extending the life of the power supply. If you need more power than the kits have, then this no-power-supply version is great. Why buy a kit with a power supply that won't work for you? If you don't need full power then why include more-expensive power supplies in the kits? The seller of this item has plenty of kits that offer a great balance of power versus cost for most people. No, I don't have any affiliation with them. Other than them responding to a technical question I posted here on Amazon once, I've never had any contact with them. But when your needs are outside of the 80%, I'm thankful to them for selling this injector that I can customize myself. I purchased a 48v power supply from Amazon: Genssi 48V DC 7.3A 350W Regulated Switching Power Supply and mounted it in a metal box I purchased elsewhere (the only suitably-sized, inexpensive, box I could find was a box made for a DSC 1832 alarm panel; just search). The power supply I ordered did not come with mounting brackets. I can't find the link where I ordered the brackets for a lot less than this link but here's a link where you can order the mounting brackets to fit Mean Well power supplies: Mounting Brackets for Mean Well Power Supplies . For better prices - much better prices - on the brackets, search for MHS014 and look for Mean Well (or Meanwell) in the results. Put this all together and you have a super reliable POE system that can fully power all ports.

Einfach und sehr Günstig um aus einem "normalen" Ethernetanschluß einen PoE Anschluß zu machen. Einzig das Fehlende Netzteil, was aber deutlich beschrieben ist und die sehr Dürftige Dokumentation (gerade zur dimensionierung des Netzteils) trüben das sehr positive Gesamtbild etwas. Trotzdem volle Sterne.

Attenzone che è un pò delicato. Poco protetto, in plastica. Fa il suo dovere ma va installato in ambiente protetto

Great simple product but be aware does not come with a power supply.
