Video camera output

Hi,
I have two factories with many people workin in them. I have installed CCTV camera and can watch the activities in my cabin television.

My question is ... Is it possible to view these images on the internet ... Why ?
Because if I am sitting at some other location I can still see what is happening in my other workshop ??
Pls advise if u know abt the hardware n software capabilities....
Or if there is a web site which can help me with this complex Problem.

Thnks for your reply
