Daewoo E&C has been installing a smart-home IoT service connected with communication companies at its Prugio brand apartments.

The company, in fact, installed a smart service mixed with IoT and the AI technology that can pick out certain voices, which the residents can use to operate a number of home appliances including refrigerators, air cleaners, thermostats, washing machines and those communication facilities connected with communication firms. The residents can get such information as exchange rates, share prices, the translation of languages, shopping and weather forecasts from the communication facilities.

The construction firm plans to add the Big Data and Deep Running technologies to its home network system and other services tailor-made to the residents’ life styles starting from the Prugio brand apartments to be allocated from the fall.

The construction firm also plans to use the 5ZSC (Five Zones Clean Air System) to measure the air from the gates and the interiors of the apartments to see if it is clean or not. The company will install the E Hall Clean Air System to measure the air outside the apartments including at the parking lots and other areas inside the apartment complexes.

The Smart Air Quality Control System will be installed inside the apartments to control the air automatically comparing the air inside the apartments and outside.

The Five Zones Security System will be installed at the Prugio brand apartments, which will include smart door cameras at the entrances of those apartments while the CCTVs with 2 million pixels will be set up along the walls of the complexes and inside the elevators to watch what’s going on including the cars in and out of the apartment complexes, and as unmanned guard systems.
