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, sound, or sensor status change. At night, some of images are dark, but with a clcik one can turn a 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 administrator to inform him about burnt lamps in the Florence stairs.
