One of many companies out there that provide the complete package and service for whatever you want to do whatever you want, they were a company i delt with a couple of years ago on some office buildings and they supplied some very flash gear that did all the things your after but it cost a tonne of money.

But if you say moneys no option the choice will be endless. From past experience its worth considering using a specialist of some kind to make ensure everything will work together in a user friendly package, theres loads of companies like this about.

Good luck, Cheers,
