AT&T lets people control homes using smartphones

US telecom titan AT&T launched a service Friday to use smartphones or tablets to activate home alarm systems and perform other duties like open doors for guests or adjust the temperature, AFP reports. A Digital Life home security and management system tailored for mobile Internet lifestyles was rolled out in an array of US cities for monthly subscription prices starting at $30 after installation charges. "People rely on their mobile devices more than ever, so Digital Life offers an easy and convenient way to secure their homes, protect their families and simplify their lives from virtually anywhere," AT&T senior vice president Kevin Petersen said in a statement. Applications tailored for personal computers as well as smartphones or tablets powered by Apple, Android or Windows mobile software let people remotely control cameras, door locks, lights, thermostats and appliances. Digital Life includes alarm systems and monitoring centers, according to AT&T. The service can be customized, and options include being able to view online feeds from cameras or remote-controlled door locks.
