    Audio issue

    Hello everyone. I have a couple of questions. I have purchased 8CH AHD DVR with 4 ports for audio input(picture provided). Also I have 3 cameras and 2 microphone of different types(the one of the picture does not have model number). The product models are listed at the bottom. I managed to wire the microphone(pictured) on to the RC49 cable and plug it to the audio in port in the DVR using BNC to RCA connector. The other microphone I tried to hook it via the camera the first time and the second time only the microphone without the camera. I tested the audio sound of the microphones with CRT TV hooked on the audio out port but the DVR did not record any sound at all. Also I have tested the sound in real time but, you can hear the sound if you are speaking directly to the microphone but it is modified and is overshadowed by a large noise. How can I capture a clear audio sound from a long range distance to my DVR without noise? Also based of the audio out port on my DVR, what types of speakers (how many ohms also) can you recommend in order to listen the captured sound(a couple of examples of product models would be fine).
