We purchased cameras DS-2CD2755FWD-IZS and microphones LE-770. We were told the microphones would plug into the audio in jack on the cameras and would NOT need external power. We hooked it all up to test and we weren't hearing any audio. We also noticed that the audio input dropdown in the camera GUI only lets you select "line in". There is no "mic in" option available. So either the microphones won't work with these cameras and we do need external power, or the firmware for these cameras are missing the "mic in" audio input option. Has anyone ran into this, or have any clue what's going on? We are in a pinch and just trying to get audio to work before installing.

So basically we need to get a line level mic with external power instead of the ones when have, correct?
So we purchased the Louroe line level mics now. We have audio, but it echoes and barely picks up any audio. Almost have to be right on the mic for it to pick up. Hikvision is killing me.
Don't think so. We were quoted the line level mic with a small power supply. Louroe is telling us we should get the interface adapter because it has a gain control on it. That may be our ticket to hear the audio better. These are the items we have:

Louroe is saying we should get this instead of the Northern power supply:
