What it does
Cool new way to monitor your stuff. I would love to know if other people are snooping through my stuff when I’m gone. Duo is a sensor that uses light, motion and a cell modem to send instant alerts when any space is triggered. It can help reduce accidents and identify theft. Think this could help a lot of people.
