Microphone - types?
We've just bought a Linksys WVC200 wireless webcam to make a low-quality
recording of a meeting. It comes with a built in microphone which doesn't have sufficient range to capture everyone talking. It has a socket for an external microphone and I've just tried plugging in an external Sony microphone (which has a little battery in it) what we use with our iRiver MP3 recorder but it doesn't work - no sound at all. I've asked Linksys to let me know the specification of the microphone socket or some recommendations for microphones but I'm not holding my breath. I'm about vague about AV and wondered if anyone could suggest somewhere good to learn about microphones. I suspect it's all to do with gain :-) This is a link to the camera itself: http://tinyurl.com/2rape2 Thanks, Rob. |

The microphone input is documented as a, and I quote from the vendor doc, "port". No detailed picture, either. Usually, ports like this are a 3 mm jack of some kind, with either 2 or 3 signal lines, and probably with built-in bias for an electret mic. A mic that is designed for use with a consumer PC sound card might work with it. That all said, the best kind of mic for picking up a conference is probably a PZM mic sitting in the middle of the conference table. I don't know of any that are designed to interface with your Linksys mystery box. |

I've got a microphone stand a home which I'll bring in to try. That all said, the best kind of mic for picking up a conference is probably a PZM mic sitting in the middle of the conference table. I don't know of any that are designed to interface with your Linksys mystery box. Thanks for the PZM bit - off to read about it. Thanks, Rob. |

probably a PZM mic sitting in the middle of the conference table. I don't know of any that are designed to interface with your Linksys mystery box. A standard PC stand-microphone does work but the range is not good enough as well as there being a lot of background noise. So on the hunt for a good quality omnidirectional directional desk microphone. Regards, Rob. |

What you need is a microphone and a mixer amplifier, and its hard to say if the camera has compression. Compression is needed regardless to hear all, including room noises. I would buy a cheap PZM type and a all purpose mic amp. Try looking in Guitar Center or something like that. Having an isolated output stage or transformer, may be critical to reducing hum. They also used to make remote mics for camcorders which may be another alternative. greg |

It turns out that a standard PC microphone will plug in except that Linksys have wired up the socket strangley. They are using the R channel which means that if you plug in a standard mono microphone, it doesn't work as R and ground are shorted together. Plug it in part way and it works :-) Rob. |

Do you have a model number or description of this, as Arny put it, "mystery" box? |

What's this "Linksys" box that you keep referring to? AFAIK Linksys is a
company, not a product. Do you have a model number or description of this, as Arny put it, "mystery" box? It was described in my original post. It's a Linksys WVC200 wireless webcam. I've ordered a 3.5mm mono socket to 3.5mm stereo plug adapter which is designed for use with stereo input camcorders but should also work with this device. Just quite why Linksys designed the WVC200 with a microphone socket which doesn't accept a standard mono-microphone is rather beyond me. Cheers, Rob. |
