It's powered by a USB plug... is there a way to convert PoE to USB power?

And the connectivity is through Wifi. (And Bluetooth during Setup)

For sure, there are tons of off the shelve adapters that'll do it. But may be hard to fit in your package.

The big part, is the power is delivered at a pretty high voltage, so you are going to need a buck converter to get it down to the 5V usb expects.

The PoE to USB solution is a "PoE splitter" and they're cheap and very useful. The website says the device has a USB-A connector for power. That's a bit of an odd connector to power a device from (since A is supposed to be a host port). Is that port really an A?
I am referring to something like this: https://www.newnex.com/images/usb-2-a-male(UH2-AE)_small.png

Isn't this called a USB-A plug?

EDIT: I cannot respond to the child comment, but yes: The Device has a male USB plug, and then the cable goes right into the device, no receptacle on the device.

I think I'm misunderstanding. The device has a captive cable with a USB-A plug on the end (i.e. not a female receptacle on the device), doesn't it?

Edit: I understand. I'm used to devices with receptacles rather than captive cables. Any reason why you went that way?

I was going back and forth on this for a long time, but ultimately I decided that a cable entering the device looks sleeker than a plug that is plugged into a socket on the frame.

Also makes it easier to place it on the included stand.
