Compatible M7WP-MIC Waterproof Outdoor Microphone for M7B77-W, M7D77-POE, Any IP Network Camera & PTZ IPCamera with Interface -an IP Camera External Microphone

I installed and tested the Microseven microphone onto a Sunba 405 PTZ IP camera and along the way also tried 2 other microphones because I was unhappy with the quality of the audio and I thought the microphone was to blame. We use the mics is to listen to backyard sounds from the birds and other wildlife through several backyard cameras all managed through a Network Video Recorder and displayed on a TV. We can select any camera and hear the audio through the TV. After much testing, we discovered the Sunba IP camera was the issue, greatly limiting the audio bandwidth. The external microphones, all 3 of them were decent performers with the MicroSeven being the best of the three (Microseven, USA SALES and Tonto were there 3). Read on for our test results.The Good:-- EASY INSTALL: The Sunba 405 camera came audio-ready with an audio RCA connector and a power connector on a dongle to attach to the mic. Just plug and play. Also, the body of the microphone has a bracket with a hole to attach to a surface.-- NICE IT INCLUDED RCA ADAPTER: The kit came with an RCA male to male adapter barrel which was great as that was necessary to connect the mic to the Sunba camera.-- SOUND SENSITIVE: The mic picked up quiet high-frequency sounds. For example, I have ultrasonic mole repellers stakes in the ground that give off a high-frequency chirp every 60 seconds. The chirp is very quiet to the naked ear and the mic pics those up easily.-- EASY TO HEAR NATURES SOUNDS: I could hear doves, birds chirping, hummingbirds squawking at other hummingbirds and owls at night-- MISTAKENLY BLAMED THE MIC FOR POOR FIDELITY: I measured the audio bandwidth of the camera-external microphone system and after much testing using special audio analysis software and a special test microphone, came to the conclusion that the IP camera was causing the poor audio fidelity, NOT THE MICROPHONE! The Sunba IP camera cut off audio bandwidth at about 4KHz while the microphone bandwidth extends well past 12 Mhz. See the attached plot showing the narrow camera bandwidth and the much larger microphone bandwidth. The IP camera digitizes the analog audio from the mic and this particular Sunba camera uses a low sampling rate resulting in very poor fidelity when you listen to it through the IP camera. The bandwidth through the camera provides an audio quality more like an old dial-up analog princess phone. The microphone performance by itself, while by no means Hi-Fidelity is very functional and provides plenty of reasonable bandwidth to 12KHz and beyond out to 20 KHz to get good quality audio....... Im don't know if there is an IP camera that will provide good bandwidth but I know the Sunba 405 IP camera does not.-- THE BEST OF THREE MICS: I tried 3 different mics during my adventure to improve the IP camera's audio and while they were also reasonable performers, the MicroSeven had the best bandwidth over the audio range.The Bad:-- NO POWER "Y". There is not a power "Y" cable connection to allow one to share the camera's DC power.Conclusion: The microphone performs well on its own with bandwidth out to 20 Khz and very reasonable levels out to 12 kHz. If you feel your audio is not up to par, look at the camera first as the likely limitation.

I was initially unimpressed with this microphone. It seemed *too* sensitive and any moderately loud noise would result in static and screeching.Recently I moved it from an old Foscam camera to a new Amcrest camera and that made all the difference. The old camera's audio input must not be impedance matched correctly and that was just overwhelming it. On the new Amcrest (an 8MP dome) the quality is great and I can finally hear what everyone else was talking about in their reviews... ability to pick up distant sounds like birds chirping, as well as nearby loud noises like my garage door opening up mere inches away, without blowing things out. It's really well balanced between the soft and loud noises.So, if you have an experience with a camera (or anything else) where the sound just seems to blow out, it's probably not the mic, it's the input circuitry on the camera.

Have had this in use for 2 years with an outdoor camera. It easily picks up loud voices from well over 100' away, picks up airplanes at well over 2000' high. Has withstood the elements nicely. I have it mounted facing down and have a piece of foam over the opening to keep out critters and the elements.I'd say whatever you can hear standing next to it, it will hear and send up the line. Speaking of line -- I have this mounted 100' away using cat 7 cable (using an adapter at each end) without any loss at all (I could power through the cat 7 as well, but simply steal the power from the camera itself without any feedback issues with video (using cctv coax cable).I'd recommend this a a simple, durable and quality mic.

This is a no-brainer install, so that wasn't an issue. I installed it with the power "y" cable, got nothing. The Dericam has audio inputs in and out. I tried disconnecting the power, switching inputs just in case, powered back on, still nothing. The Dericam software allows you to select microphone or line inputs..this is powered, so I tried both (similar to phantom power, you can't hurt the mic if you connect the mic THEN power it up), got nothing either way. Bought a separate Dericam 12v power supply, one for the camera, the other for the mic in case amps were too low. Still got nothing. Covered all the variables except one...I just happen to have ANOTHER Dericam S1 in the back yard so I tried it all on that one, too. Same amount of nothing. Tried the it on a Tascam 701D, with both line and microphone settings (I use that for podcasts), got nothing out of it either. You can hear a very faint crackling on either setting when the camera starts recording but that's it. I tried the input and output volumes at different levels throughout the range, didn't do anything either. I'm a good enough tech that I know what I don't know. But I've exhausted every avenue and spent every second I plan on to try and make this work with this camera (which is the best of the four PTZ's I've tried, bar none). I've no doubt it likely would have worked with my old CCTV set up, but I'm done. Input from seller? Use 12V power supply. Seriously? This is going back. I'd try the Dericam dome mic that says it's for this camera but the reviews scream "cheap junk". And this mic doesn't feel or look cheap, so the problem is with the interface, or somethings broken. I bought a different Dericam branded mic that I'll try tomorrow, and I'll bet I have exactly the same experience.
