Has anyone hooked a mic up? Will it support a passive mic?
yes, I have used a passive mic (mic arm snapped of an old headset) I've also connected a powered mic.

Both worked reasonably well. The huisun lacks the in built environmental noise reduction of my hikvision so background noise is a little loud though. I have been better able to adjust the volume and gain in both the camera and also blue iris to get better results from the powered one.
