A door closing alarm is a security device designed to alert you when a door is closed or opened, offering added protection for your home or business. Typically, the alarm is activated by a sensor that detects the movement or vibrations of the door, signaling when it is closed. The device emits a loud sound, such as a beeping or ringing noise, to notify you of the door's status. Some models feature adjustable sensitivity settings, allowing you to customize the alarm based on the strength or force of the door’s movement. Door closing alarms are commonly used in high-traffic areas, homes with young children, or businesses to monitor access points and prevent unauthorized entry. Easy to install and use, they provide an affordable way to increase security by keeping you informed whenever a door is opened or closed.
