Smart Homes allow automated control of everything from lights and locks to curtains and cameras, TVs and temperature, with the promise of increased convenience and security — but Marketplace reveals the more devices you have, the more vulnerable you could be. In this episode, we find families whose security cameras are streaming live on the internet, showing them in real time how they are being watched by strangers around the world.
