M7WP-MIC waterproof outdoor Microphone for M7B77-POE, M7B57-WPS, M7B77-W,M7D77-POE, Any IP Network Surveillance Camera & PTZ IP Camera with Audio Interface -An IP camera external microphone

Great outdoor microphone. Using this mic in conjunction with Night Owl 8 Camera HD DVR. Use this Audio cue to hear when the delivery truck from Amazon gets near - look up to the monitor screen and the Camera confirms the delivery person before they ring the bell. Mount with mic facing down so moisture and dust won't get into the mic. Stars:* High sensitivity. Will pick up dog panting from 30 feet away. Only need one mic if your cameras are less than 30 feet apart.* Easy to connect, use the regular BNC cable fitted with BNC-RCA connector.* Power cord splitter comes with the mic and just plug and play.* Reasonable price for a good performing mic. Works well with Night Owl 8 Camera HD DVR.* Rugged Aluminum body to protect the mic unit from outside elements.Strike: - Will let you know as only time will tell about durability. NONE working good after 2 years in outside environment very sensitive mike. Bird built nest above it still works well.Will buy one more of this mic for interior audio recording for all (4) indoor Video Camera. Amazon has great delivery and customer service. Wished I bought Amazon stock way back then.

great mic for the price, but it really needs a beefy windsock if you want to use it outdoors. the slightest breeze clips the mic without one. i ended up making myself one out of foam and it works great. i can hear conversation fine at over 30 ft away.

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 bought 2 of these microphones, failing to notice that I had no RCA to 3.5mm connectors, I had to wait a while to get everything set up to test. Plugged one into the 3.5mm "in" on my camera, this was a new 3.5mm cable, used a 3.5mm to mono RCA adapter and then the included RCA to RCA. Then plugged the power in using a 12V 1A transformer. No output. Swapped the 3.5mm cable, swapped the 3.5 to RCA adapter. Then swapped the Transformer to an active POE splitter that outputs 12V, 1AMP. Finally opened the 2nd mic, swapped the RCA to RCA, and finally swapped the mic. Nothing. Power confirmed from the POE splitter and the transformer.Unplugged everything, pulled it all upstairs to my desktop. Connected everything to my PC, and set it up as a mic, no sound coming through. Repeated my replace a single component test until everything was replaced. So having replaced all components of the system, both mics were DOA.Unfortunately for me, the time it took for me to sit down and troubleshoot this, my window to return had expired. Would not recommend unless you can test immediately.
