Crestron is a brand that allows portable digital devices (iPhone’s and iPad’s) to remotely control other devices, IT-enabled appliances. Such as lights, TV, DVD player, security system and thermostat. Using their application, the user can experience a SmartHome by controlling most of it with their cellphones.
The links below mention and comment Crestron as one of the leading brands in the building of a SmartHome. Considering the prestige of The New York Times and Forbes as sources, I think that this brand would be reliable and valid for use.
