Need help to setup service for live video camera

[David Harel]

Greetings,

I am looking for a recommendation on how to provide live video streaming
from one or more video cameras to several viewers on the web.

The cameras IP address should be kept secretive. 
The service should support one or more video cameras.
The end user should be able to select the desired camera (maybe using
different URLs).
The end user should be authenticated.

The end user interface should be similar to Israel National Road Company
