On this installment of Designing Spaces, we look at three measures homeowners can take that will upgrade their home and provide for a more fulfilling and secure lifestyle. First, we start visit one home with a recently installed, wirelessly connected security system that covers everything from carbon monoxide detection to professional monitoring and notification of any undesired activities. Then we roll up our sleeves and take on a DIY project that breathes a new life into the wood deck in a backyard. Finally, we kick back and enjoy music and sound like never before with a digital audio system.
