Ruby: Grab a single JPG image from an authenticated IP CAM and save to a file

Question

Using ruby, what is the easiest way to grab a single JPG image from an IP camera that requires authentication and write the image to a file? For example an IP camera that has uses a URL:

http://192.168.69.81/cgi/jpg/image.cgi

I don't need to perform any manipulation of the image.

Thanks in advance.

Open the remote location and write the file as a jpeg image called image.jpg:

require 'open-uri'

url = 'http://192.168.69.81/cgi/jpg/image.cgi'

open(url, :http_basic_authentication => ['username', 'password']) do |f|
  open('image.jpg','wb') do |file|
    file.puts f.read
  end
end
