What are the differences between HD and Megapixel cameras?
Over the last year there has been an explosion in the number of manufacturers offering megapixel cameras, with many reaching over 3-megapixel.

HOWTO: Axis Internet Dynamic DNS Service
IP security cameras allow you to view your home or business from anywhere in the world with access to an Internet connection. To connect to your camera you need to know the IP address of your Internet connection that your camera is connected to. This is known as the ‘public’ IP address.
