CHECK DVR AUDIO INPUTS Before thinking about the mics, think about the DVR .  The microphones (even ones built-in to cameras) need an input on the DVR.  Buying 8 cameras with 8 mics for an 8 channel DVR that only accepts 4 audio inputs is a frustrating experience.  Make sure to view the specs of the DVR for the audio inputs and don’t forget the speakers.  The DVR will have an audio output but the speakers do not come with it
