My experience trying to power the MR24 with "passive PoE" and/or less than 48V were not successful. You really need a standards compliant PoE injector for them.
Apparently there is/was a patent on the chips that do/did the IEEE PoE standard, which made them too expensive (I recall something like $15/chip) for commodity grade hardware and so price-sensitive vendors like Ubiquiti basically said "F-you" and used lower (12-24V) voltage PoE instead. Meraki isn't price sensitive hardware.
