CCTV Microphones

Hello all.

There are CCTV microphones on ebay that have 3 input jack, one of which is data cable (audio out). Also the ones that have 3 cables, two of them are for DC and one for data (like this one)

Are these wireable to Arduino as the electrets like this one, i mean to get ADC response relative to the noise in the environment?

Possibly but that web page does not give many technical details.

Then you will need an envelope follower on the end of that sparkfun circuit.
