Weather
Live images of web cams installed to check the weather, and doors. Each cam is capable of sending an e-mail every time there is an image change. At night, some of images are dark, but a motion sensor turns the light ON to trigger an e-mail. Simultaneously, we may detect a burnt light bulb that needs to be replaced. I enjoy calling, from Berkeley, the building manager in Sesto Fiorentino to inform them about a burnt lamp in the building stairs.
