Andersen Windows’ VeriLock integrated sensors allow occupants to monitor their windows and patio doors while at home or when they’re away through remote access. Users can view multiple zones from a central monitor to see whether windows and doors are open and closed, as well as locked and unlocked, ensuring the home is secure. We spotted the sensors while walking the trade show floor at the 2015 Greenbuild International Conference and Expo in Washington, D.C., in November. Check out the video above to learn more about the product.
