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

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.

The Vanxse Microphones I Rate as one of the Best out there for Outdoor use, Although I do have mine installed in a Plastic Box (Plastic Electrical Receptacle Boxes) to keep the Rain & Snow off of them. They are Very Sensitive, with Volume Control. I can actually hear the Deer eating Grass, Squirrels chasing each other, etc etc..! Superior Sharpness against other Microphones I have tried..!You can hook them up on the Audio Input Port on the back of your Surveillance DVR for recording Audio along with the Surveillance Video Cameras, or what I had to do, was order a Mini Hi-Fi Microphone Stereo Audio Amplifier. I believe it was around 13 bucks, and 2 Mic's can be hooked into it, then I ran a pair of old Computer Speakers off the Amplifier.. (My DVR sounded like Crap with Audio Microphones hooked into it)Vanxse Microphones seem to be getting harder to find, so I Always order Extras for Backup, Mainly because Lightening Storms here on Top of my Mountain, Close Lightening Strikes do Take them out. Over 13 Years I've had to replace mine out on my Workshop metal Building 3 times already due to Lightening Storms..Overall, Best Bang for the Buck, Order Extras, you'll be Glad you did..!

Wanted to have sound for one of my cctv cameras that would be 20-30 feet off of the ground floor. I used a bnc cable (with rca adapters) to connect the audio output plug from the mic to my DVR audio input, along with power. Once I connected the mic, I could hear, very clearly, conversations 20 feet away, and other sounds more than 30 feet away clearly. I was shocked how well this little mic could pick up sounds. Awesome little device! If you're thinking about purchasing a mic for your security camera....this should be on your short list.

Great security microphone. When I took it out of the box, I was a little skeptical. I got it hooked up to my system and I was surprised at what I could hear with this thing. It is amazing. It has a gain screw on the under side of the unit, I adjusted mine full clockwise then backed it off a quarter turn with a small phillips head screwdriver and it picks up everything and it's not even at full gain! I recommend this product. I really don't think you'll be disappointed. I plan to get another one of these.....It is well worth the money.

This product is amazing except it doesn't work...or at least I haven't gotten it to work and it seems pretty straightforward.

No matter how I wired this and what filters I ran it through I still got a certain degree of static and interference. I have yet to solve the problem of why it did not work well. It appears to be made very well if I could never work out the problem why there's an interference it will be worth the money.

So I ordered this to add audio to a remote CCTV camera, and wasn't sure how well it would work, but this thing is pretty awesome. It's smaller than I thought, with a solid metal case and small holes for the mic and gain control. At full gain it could easily pick up a quiet conversation at 20 feet. I think it will serve my needs very well.

If you wanna capture the neighbors squealing tires, revving engines, loud music, and dogs barking all at 4 am this works very well, worked for me. Once the cops told them I had the video with sound and I could use in to file formal charges, the nonsense stopped. If you want to hear a cat fart down the alley, nope not that good.For the cost, it did exactly what it said it would do and exactly what I needed.
