There actually isn't anything particularly complicated about the setup you're describing. It is definitely doable but the first thing you need to decide on is a budget. There's no point in anyone tossing around product recommendations until you give people an idea of how much money you're able to spend.

Also, is this something that you want to set up and maintain yourself or are you okay with the idea of hiring a pro to do it? This is an important consideration since many of the products in this field are "protected" lines that are only available through authorized dealers and it can often be very difficult if not impossible for an end user to get the proprietary software needed to set the system up.
