You don`t necessarily have to get rid of a working analog CCTV system in order to update to a broadcasting video that can be monitored from any internet connected station or 3G phone. Video capture cards can digitally convert the pictures for broadcast. Until recently, there had been no real attempts to standardize the new IP cameras; every make and manufacturer functioned a little differently. And when you throw web cameras into the mix, finding one software to control them all was heavy.
