IP camera kits ( 6 cameras ) with audio as well as video

Hi all!

Does anybody know of any outdoor IP kits, that come with 5 or 6 cameras, where each camera also provides audio (or has microphone in on the camera), so that each channel has both audio and video?

I've looked high and low and can only really see video on these things yet my ancient camera has a built in microphone so looking to upgrade but the audio is quite critical really.
