Don't buy it if you are trying to use it as a webcam ... or better yet don't buy it. For 150$ you get what you pay for. I didn't like the optics at all. It does support output to HDMI and RCA and USB. The downside is that if you plug in using the RCA or USB the camera shuts off. Pretty much useless for this type of activity.
Good concept, cheap, waterproff (apparently), about as small as an Iphone.
