What cameras / server do you guys use? How about reliability? I have two jobs for the same guy who wants us to put 8 cameras in two of his homes so he can monitor usage of the houses from his third home. All 8 will be bw infared with 2 needing audio. I've played with the greyfox cameras here @ the office and the seem to pretty much do the job but they don't do audio. Thanks in advance for the advice
