I need 3 consumer level Hi Def camcorders with wireless microphones to record 3 simultaneous workshops indoors for a total of 8 - 9 hours. I have no preference for either Hard Drive or sd cards storage. The camcorders will be plugged in the entire time. The videos will be edited for viewing either on youTube or Vimeo.
The cameras will be on tri-pods no more than 20 - 30 feet away and turned only to focus on one panel member at a time.
The audio should be reasonably clear and doesn't need to be perfect broadcast quality.
Any suggestions about which camcorder, external microphone & place to buy them? I'd prefer cost of each camera/mic set to be no more than in the five to six hundred dollar (US) range.
