Vanxse® Mini Microphone High Sensitive Pickup Audio Mic waterproof Metal Case for Cctv Security Camera DVR System

Very good microphone. It can pick up the sound of a hedgehog eating biscuit at 20 metres away!! and that is not even set at maximum gain!! Easy to install and wire up. Sound quality is very good for my amateur ears with my CCTV. It will even pick up conversations in the house so be warned!!!!

Performance is too bad and never recommendable.

I purchased this to provide sound on my CCTV system. It is easy to fit - just screw it onto the surface and plug the power and sound cable into the lead to your DVD. It works very well picking up the sound well with not a lot of background noise.

1 star off for misleading ad or box? 4 stars for decent sound at a low price. Ad says 16000hz, Box says 6000hz. VMS software only lets you select 16khz or 32khz. But it works, so either VMS doesn't really care its 6000hz, or its really 16000hz & the box is wrong? This one makes much less humming than the "power passthrough" version. That one wouldn't work well and made a loud humming noise with the "denoise" feature on from VMS. Whether you used power passthrough or not. Much better sound with this one with "denoise" on. I made a wind sock from AC pre filter "open cell foam". I cut a length a bit wider than the mic, wrapped the mic twice, then used lo temp hot glue to keep it in place. Then glued the open sides shut like a pizza roll if that makes sense. This made it even better because we have a slight constant wind in michigan which would cut out any sound that isn't loud. Windsock pizza roll worked perfect and its very clear. Hope this helps someone.
