There is a ubiquiti poe injector, 48V output.
And there is a device that requires 12 (IP camera).

YES, definitely

Answer 2

it's tantamount to eating if you owed the bank 12 rubles and the bank said that you owe 48, mathematics and fantasy are our everything, don't touch it)))

Answer 3

Understanding electronics is very easy with examples from fluid dynamics. The analogue of voltage is pressure. Imagine that you sent water at a pressure of 48 into a pipe that can withstand 12 atmospheres? What will she do? Will burst.

Answer 4

put a PoE splitter on the other side, which will convert 48 to 12 and allow you to power the camera.
look at the documentation for the camera, many ip cameras can work via PoE /
