Chasecam PD100 = 720 x 480, 30fps, ??mbps, max 32GB CF card .... This is DVD quality with the assumption that is records at 4mbps.

RCA Lyra X2400 = 640 x 480, ??fps, ??mbps, max 2GB CF card .... This is VGA quality with the assumption that is records at 30fps.

I think that the recorder choice depends on your plans for the final video result. Do you want it for youtube or to create broadcast quality videos .... John Stead
