Installing a home theatre sound system can be difficult, so when you're planning the upgrades, remember the advice of Techs in the City's Stuart Davies: be prepared.Training can vary. You can either go to uni or TAFE - I went to TAFE because I think there's more of an emphasis on teaching practical information there.
You need the person to understand your specific needs, because the field of IT is so vast. You don't want someone to baffle you with jargon. Make sure they're listening to what you need, and make sure they have a good knowledge of the different types of home theatre sound system that are available.
Any person setting up a home entertainment system is often privy to your passwords, so you need to know that they're trustworthy. They could gain access to your emails or even your security systems, so honesty is a huge factor here.
The goal is to have all your data in a central place, with the ability to view it around the home. So rather than having a few computers with photos scattered everywhere, you have just one that stores all your pictures, music library and movies, and then these can be played anywhere in the house.
I set up all my systems to back-up every week, and I also strongly suggest doing an offsite back-up every month.
If you're building your home then I'd suggest you run CAT-5e wires throughout and have data nodes in each room. Otherwise wireless is great, especially because you avoid drilling holes in walls. A wireless home theatre sound system has become very affordable - you just need to find the system that suits your home and budget.
