During our coverage at CES 2009 we utilized Sanyo XACTI cameras for our back channel coverage. The reason we picked the XACTI this year was due to the fact that they devices encode in H.264 / MP4 format.
Last year we utilized cameras that recorded in .AVI and we lost a lot of time converting the videos into a format we could push to streaming sites.
Sanyo is introducing a full line of new XACTI cameras this year. If your looking for a easy to use camera you will want to check out what the folks at Sanyo have in plan for the XACTI line this year.
