def camera_video_uri(size = :full)
  case size
  when :thumbnail
    resolution = "160x120"
  when :medium
    resolution = "480x360"
  when :full
    resolution = "640x480"
  end
  "http://#{hostname}/axis-cgi/mjpg/video.cgi?resolution=#{resolution}&text=0"

#snapshot_jpeg(size = :full) ⇒ Object

Returns JPEG data with a snapshot of the current camera image.

To dump the JPEG data to a file, you can do something like this:

# Instantiate c as a AxisNetcam::Camera object, and then...
data = c.snapshot_jpeg
f = File.open('/tmp/test.jpg', 'wb')
f.binmode
f.write(data)
f.close
