I would like to access the hive mind of DSX. I have a client that is looking to be able to place a mic on the outside of a building for a full year, and get recordings through all that time. The recorder can be inside the building so that part of the equation is covered. But any advice on a mic that can handle the heat and condensation of the hottest days in summer, the rain blasts that come with Spring and the sub-zero temperatures and ice that are a part of winter would be appreciated. Ideally the mic would be self contained as if a blimp is needed I think it would just get waterlogged after hours in the rain.
I have found some mice that are meant for outdoor intercoms and similar applications but they are very far from offering a full frequency range. Crown makes a boundary mic that is the best thing i have seen so far, but its frequency range does not go very high.
Let me know if you have any ideas.
Would a DPA 4060 heavy duty mic do?
The specs say it will handle temperatures between -40°F to 113°F and humidity up to 90%.
These videos go a bit further then the specs:
and from DPA
Let me know.
I think your construction depends on the quality and budget of such a project. If you need high resolution, a good microphone is necessary. DPA has some robust microphones, like the 4006 series. They are not cheep but they will deliver the source of 365x24h of recording! And you need to protect them. Putting them on a rooftop is not a good idea. In case of heavy rain or strong wind, you will not get any good results in recording, only distortion if the wind can full attack the microphone. Can you place it somewhere under the shelter? Otherwise I’d recommend you to bild something like a bird-house with a roof and put the microphones into windshields. Temperatures arn’t such a problem, I recorded at minus 30° up to 45° Celsius. Temperature is a problem when equipment get shocked, for example if you bring your frozen stuff into a warm room.
Moisture is probably the biggest enemy on such a project. Why not using a dry bird-house to protect the microphones?
Also checking the installation from time to time would be a good idea. A bird-house is not thought for microphones, and maybe you will find a bird-family living together with your expansive gear. If that happend, please send us a pic!
And let us know how and if you did that, would be interesting to hear about.
A friend of mine uses XM8500s. I’m pretty sure that’s the model number. He uses them to stream what’s going on outside his house to the internet via a Raspberry Pie I think it is to the internet. I think he’s had them out for a year or more in his garden and they’re still fine.
They are dynamic microphones. Obviously they will suffer from wind noise and the sound of rain-drops donking on the mic if not sheltered at all and obviously they will need to be secured but they are inexpensive and sound good for their price-point.
