Record your video in a quiet space, a room where you can control the sound, where you can close doors and windows.

Generally you want the camera / microphone as close to the subject as possible.

Take care not to touch the camera during recording as that sound often gets transferred to the camera microphone. A tripod is helpful.

Lastly try to be aware of background sounds: a squeaky chair, shifting papers on a desk, a refrigerator, an air conditioner. Keep these background sounds to a minimum (unless they are intended part of your video) .

Good luck with your web series.Camcorder microphones, any Camcorder, the best audio quality can be had at a 4 foot distance from the camcorder. Beyond that, audio quality starts to diminish. They noisier the environment, the steeper the fall off.
Keep the person at a good distance from the mic, speak clearly, don't be too close or too far away from it.
