Does anyone know if there are audio extenders that can be added to the system?

This camera works terrific.  Get's a full range of video.  However, the audio doesn't cover the entire area covered.  Does anyone know if there are audio extenders that can be added to the system?  We do not need another camera because we have the coverage needed but the audio is only clear for sounds closer to the camera.

Use of a computer to view/download the videos may be useful since there's more control over audio.
