Which miniature camcorder has continuous composive video out?

    I've been playing with the Sony HQ1 miniature camera, but the quality
    is not what I need.

    My Sony HC1 HD camcorder is great quality (using the same video to USB
    frame grabber) but much too big, and also it shuts down if not
    actually recording to tape.

    I need a small camcorder which can just run for say 10 hours,
    generating a composite video output. I don't care what media it might
    record to. It will need external power of course. Doesn't need to be
    HD.

    The problem is I can't go into a shop, with my laptop and a video to
    USB converter, and sit there for a few hours to make sure the thing
    does what I want...

    Basically, I want a high quality webcam! But there aren't any. The
    most expensive Logitech ones are actually pretty crap - I've tried
    them.

    Any suggestions would be much appreciated.

    That's right. It just will not respond to the 'record' button.
    Somebody thinks there is:

    Firewire usually carries DV25, while USB usually carries MPEG2. The
    degree of "quality" is of course in the eye of the beholder.
    Some of them are even 100base-T ethernet - probably even 1Gigabit too.

    Riiiight. And I bough a pair of "High Quality" computer speakers
    at the dollar store last month. For a dollar.
    Since the OP is reporting that conventional USB webcams are
    NOT high enough quality for his requirements, we already have
    a reference point for "eye of the beholder".

    In my experience all miniDV camcorders will do what you want.
    They continuously pump out both firewire and composite for as long as
    you want...
    You can get a used one very cheap. Don't bother if the tape mechansim is
    broken, since you won't need it!

    Thank you for the tips - I will try a few things.

    I did plug the video o/p from my Sony HC1 camcorder ($3000 2 years
    ago) into the USB frame grabber and the resulting video was excellent.
    These frame grabbers are c. $60 on Ebay and all use the same Philips
    chip - a 9-bit per colour ADC and a USB interface.

    I have a Logitech webcam, top end one, which should do broadcast
    quality video, by looking at the # of lines resolution, but the end
    result is nothing like that, as one would expect.

    The Sony HQ1
    http://www.dogcamsport.co.uk/sony-hq1-550-helmet-camera.htm
    is a waterproof camera designed for outdoor mounting on rally vehicles
    or motorcycle helmets; its quality is better than the Logitech webcam
    but there is quite a bit of geometric (pincushion) distortion which I
    suppose one could fix up in my Premiere Elements (not sure though) but
    the resolution is again nothing like the 576 line PAL spec.

    This video
    http://www.zen74158.zen.co.uk/misc-files/tempelhof-vcd5.mpg
    came from the HQ1 camera, and the details are here

    The video suffers from having been done through a curved window, but I
    can get around that.
