Here are the power requirements

WV-SFR311 DC power supply: 12 V DC/340 mA/Approx. 4.1 W PoE Device: 48 V DC/130 mA/Approx. 6.2 W* (Class 2 device) WV-SFR310 DC power supply: 12 V DC/310 mA/Approx. 3.7 W PoE Device: 48 V DC/120 mA/Approx. 5.8 W* (Class 2 device) * ONLY CONNECT 12 V DC CLASS 2 POWER SUPPLY.

"PoE Device: 48 V DC/130 mA/Approx. 6.2 W* (Class 2 device)"

This is what you want to look for. With POE transmitters, shouldn't be too hard to find.

I don't have a way to power this outside of POE

If this is the case why did you say you had 12VDC?

You do not have12VDC power. You have PoE only. and you injected a random bit of info from the manual about using 12VDC to a PoE discussion. This would be a problem.

I thought it related to the POE power consumption of the device and it doesn't.

The manual has this information:

Power Source and Power Consumption
WV-SFR311 DC power supply: 12 V DC/340 mA/Approx. 4.1 W
PoE Device: 48 V DC/130 mA/Approx. 6.2 W* (Class 2 device)

So you have PoE and this is the voltage you need. 48V with 130ma / 6.2W available.

48V is standard negotiated PoE, that almost everything uses. You can find these anywhere. You just need to find a unit that supports the power you need.

UBNT famously uses the 24V passive PoE standard for the UAP line and is not a company you should be buying PoE injectors from.

Brand not withstanding something like this would work.

I use these when I need third part injectors for something.

That's very helpful information. Thanks

And is what I could not recommend until now because the question was muddied.

I agree with you. Sorry

the camera has a 12V DC power supply. Do I need a specific POE injector? I'm assuming I do.

WOW, all than angst!

I read this on my phone at first and read it to mean (though in reading it now on my computer i could see others taking it to mean something different) that the camera could take EITHER 1) a 12 VDC wall wart OR 2) POE.

POE is a known specification, so just buy something saying it will provide POE and you should be golden.

But it looks like you're already sorted.. so that's good.
