Hi i have a couple questions about Security Monitor Pro before I purchase. 1. If i continuously broadcast but never view the stream, is there any data still being uploaded/being used? 2. If i purchase the current version is it free upgrade for subsequent versions? Thanks for your help.

When you start broadcasting Security Monitor Pro will start listening for a connection. Data is only transferred when you view a broadcast from a remote PC. If there is no client connected to the broadcast stream, there is no data usage. If you make a purchase of version 4, you will get free updates to all releases numbered 4.xx. When version 5 is released you will be able to upgrade at a low cost.
