IEEE 802.3af camera and POE injector

[richard951 0]

I am looking in purchase IP camera with IEEE 802.3af compliant camera. to get Power, I've got a POE injector like such:

Can IEEE 802.3af compliant camera operate with 12V feed from the POE injector? Or do I have to supply a 24V or 48V to the POE injector?

802.3af requires 48vdc. And I would not trust that piece of junk from ebay you linked to...(no offense)

Odds are, even if you have 1 camera now, you'll want to add more so you would be better served by getting a PoE switch. Look for one that is full power on all ports as cheaper ones tend to have power budgets that limit how many ports you can use. I use ZyXel on the lower end, about $70 for an 8 port switch (4 are PoE) and no power brick, plugs straight into an outlet.

Agreed, and Zyxel is good quality/reliable I've found

I saw the same Ebay POE injector from Johnathan Oxer SuperhouseTV. With your advise, I decided to go with the POE switch. Thanks! However, I would like the POE Switch to be mounted on the camera pole next to three IP CAM. Can I use one Ethernet with 48VDC injector/slitter to power the switch from 50-75ft? I also created a new post with same question.
