The microphone arrived promptly from California. I installed according to the pictures provided here and on the M7 website.
Frankly, it didn't work at first. About the same time I bought this mic, a firmware update was released, which I installed, that caused the microphone to malfunction. A very recent firmware update, v1.2.7, fixed most of the problems, and it now works.
Like most microphones used outdoors, this one is susceptible to a lot of background noise due to wind and traffic. I have adjusted it now to work pretty well and recommend it for those who need audio.
The wiring is somewhat bulky and may require a covered outlet box for outdoor use.
I must say the Microseven camera is excellent. I have the wireless model working 200 feet from the house, no problem. And, the nighttime picture quality is excellent.
The M7 support staff was very helpful and responsive, by the way.
