How does RA-CCTV work ?

The camera is behaves like an internet server hosting a website. When the user types in the web address of the camera, it returns a video feed to the user as though the user were watching a clip on youtube.

If the camera is connected directly to an internet cable, the way this works is -

1. User types in web address
2. The web address is automatically translated into a number - the IP address. This number is like a postcode signifying where the camera is physically located so that your computer can communicate with the camera
3. The camera opens a line of communication with your computer and then sends your computer a video feed.
   

If the camera is connected through a router the process is slightly differnt -

1. User types in web address
   
2. The web address is translated into the IP address of the router
   
3. The router then forwards any communication to the camera. All dialogues between your computer and the camera are sent through the intermediary - the router.
