A doorbell is a device installed near the entrance of a home that alerts residents when someone is at the door. Typically activated by pressing a button, doorbells produce a sound, such as a chime or ring, to notify occupants of a visitor's presence. They can come in various styles and designs, ranging from simple mechanical bells to modern wireless systems with video capabilities. Some doorbells may also include features like intercom systems, motion sensors, or smartphone connectivity, allowing homeowners to see or communicate with visitors from a distance. Doorbells enhance convenience and security by providing a way to announce visitors before they enter.
