Thanks @Shoei , that was how I read it too.The only value quoted on the datasheet is 0.707V RMS max signal into the audio input, can't see anything about phantom power.

Hi Charlie,The cameras are poe
Why do you need an extra power supply?
Just plug the microphones into the jacks..
Are you aware of the legality of recording voices rather than just images?
This maybe a silly question, but would this one power all 10 microphones? Also, would the great distances (upto 75 metres) cause issues here?here. 4A, so easily power your devices/
What voltage is your POE power supply? The Bosch camera needs 12V but will work up to 48V. If the supply voltage is high enough the simplest way to power microphones would be with a POE splitter/regulator, this sort of thing..
Jim is correct here. We have already tried this and there isn't sufficient power to power the micOkay, fair enough, I must have missed that in the camera specs. I'm not convinced the order of mV is enough to power a mic amp to drive the audio line level input though.
The PoE is HIKVISION DS-3E0326P-E. Due to the distance, the PoE had enhanced power outputs on the switch ports.
I have heard mixed reviews on the splitters. Would these diminish the performance of the camera device itself?
Thanks Jim, you have been super helpful!It looks like your PoE switch is 100Mb/s not 10Gb/s. The splitters @Shoei linked to are compliant with a 100Mb/s newtork so I'd buy one and test it out
The cameras only need a couple of Mb/s each at full resolution so it may well be that a slight drop in network performance makes no odds.
