Joyzan High Sensitive Weatherproof Preamp, Microphone Audio Pickup Microphone Device 100 Square Meters Wide Monitoring Range Portable Life Recorder for CCTV Security Camera

Looks like a golf ball on the ceiling. Wide response range, very powerful while only drawing .3a of 12v I'd love to test more products from this company.

My USB hard drive plugged in to the other side of my computer started smoking when I plugged it in to my computer I guess the 12 goes right thru it and into my 5v USB plug & started smoking stuff I didn't think that would happen but now I do and so I'm telling you too. Had USB to 1/8" mic and speaker adapter and the 12volt between the two of them was not isolated. Yep dried my brand new hard drive I don't want to blame anybody. My hard drive screwed up brand new. It was $50. Lost all my data that I just put on it but I don't know somebody could have said something about it. Probably not to use on a USB or something. Now I know it's not like I just hook 12 volts up to my USB plug. You know I just plugged in this Howard microphone so don't think that everybody should know that it's going to go through everything and burn it up. Other 12 volt of things do not do that but just wanted to put it out there. Maybe it works good. I don't know. I've never seen it work yet. The microphone anyway. That was that happened and that was that

It says 100 meter range however the only thing you can hear is when its being touched. Can barely hear anyone in the room talking even when they are right up on it.
