The person who opens the door.
A door knob turns to let people open or close the door. For vehicles, a lever or button-lever opens the door. For swinging doors, body weight (pushing) opens a door.
A security door chime can serve as a doorbell and as a security device. By wirelessly transmitting a signal and sounding an alarm, the chime makes sure people know when their door opens and closes. This type of product provides essential information to the occupants of the status of their door. Businesses can benefit from a security door chime because it will alert employees when a customer has entered their store or office. This helps them provide prompt customer service and avoid unnecessary surprises. For a relatively small price, families and businesses can feel more secure.
