Sure. Here's the search for some camcorders.,aps,277&rh=i%3Aaps%2Ck%3Awireless%20microphone%20for%20camcorder

I don't see you providing camcorder details or a manual so in short, there are such things but temper your expectations as anytime you add more layers to the audio or video channels you lose a little quality.

My favorite remote audio recorder is a Sanyo ICR-XPS01M. Later in post production (some call that video editing) we can add this audio back in.
