New alarm system


I want to buy an alarm system for my house, preferably one that knows when myself or my partner are home so I don’t need to enter a pin on a keypad to am and disarm, but happy to if needed. I do want a normal looking sounder and beacon high level at the front of the house. When the motion sensors get triggered I would like my camera to begin recording and my lights to come on ( already have these working with ST so that’s not a problem).

Any recommendations on systems that are already built to work like this or would I need to get a code built and modify electronics in alarm panels etc.
