Bullet cam Microphone position in open top sports car?
Discussion
I tried my new bullet cam yesterday at Brands. The image quality is excellent but the sound is awful, it sounds fluffy and distorted. It was in my open top race car and I had the Mic near the floor of the car on the passenger side.
Where would be the best place to put the Mic and should it have something wrapped around it to avoid wind noise?

You need a "dead-cat".

You can either make yourself one (platic fizzy drink container, drill hundreds of holes in it, cover in fluffy stuff) or buy one.

Hi Tim.
What took you so long! How's life in the 'Easy' track?
What Joust said. I had terrible trouble myself. Problem eventually solved by cheapo mike from cheapo shop.
Good luck.

Steve, it's been too cold to go out, Easy Track is still the same and Marcus never changes
The microphone I have is a tiny lapel mounted type thing that came with the camera, should I get a bigger one of just do as Joust says and stick this one in a drinks container? Hankscorpio said:
No help at all but was that the Jaguar with the cam on the roll bar?
If so, it was very nice indeed and lovely to see.
Yes that was my car, it got a tad wet later on though but was good practice for a bit of wet weather driving.
I need to get a Fire wire cable so I can upload some to the PC and have a go at editing it.
As Steve says, the cheapest, "cheerful" and generally largest microphone you can get your hands on, stuffed in a dead cat, generally produces the best results.
Small ones, especially "directional" ones, suffer from wind noise more as the diaphram is smaller and hence more prone to generating wind eddies around it.
Something cheap and cheerful like this should be quite good..

Here's a short clip from Brands

It's 25mb so may take a few minutes to buffer before it plays. Steve as you have dial up, forget it.

OK, I bought a cheapo mike and it didn't work. I went to Maplins (cheapo shop) and the nice man says it needs to be a powered mike. He then showed me what I need and when I asked about the connections he said the poor sound is also because I am using phono leads and it either needs line connections(I think) or a pre-amp. Think I'll stick to crap sound and dub some music over the top.
You might want to consider a pair of mini clip on drum mics and a cheapo mic pre-amp.
Or you could try a Beyer MCE72. It is a stereo mic that can be battery powered. It includes a cable that terminates in a stereo mini-jack, I would assume that iswhat your mic input will be on your camera?

I am currently experimenting with three small preamps to cure this very problem (to allow use of a normal microphone whilst using a bullet camera). I will get back to you with my results after i've finished a bit of testing (nice excuse to rev the car )
The mic input on the camcorder is disable when using a bullet cam in the AV in, hence needing a mic with preamp.

I did look at a powered mic but when I asked about the conections, Maplins man said the phono connections are a problem. How big and heavy are pre-amps? this is going in a race car and space and weight are limited.
Ran my RF Concepts Bullet Cam with the Mic that came with it in my Westy for the 1st time a couple of weeks ago at Donington and mounted it just forward of the gearbox.
I'd wrapped in an half inch of foam and got great engine and gearbox noise.
I'd heard a lot of people say they couln't get much sound from there's but had no probs. It works great.
