Hi, I'm interested in implementing smart home features in my new condo unit, but have zero knowledge on the how and what is required. I'm thinking something along the line of smart door lock for the entrance door, several units of camera for monitoring remotely, alarm system, remote control of lighting/aircond units and smoke and fire detection alarm, perhaps coupled with several smart socket that could turn on and off other legacy appliances. How much does it cost to implement the above and is there a trusted and reliable contractor/vendor that could give advice and perform the installation?
