Door Chime for Business/Home/Office/Store When Entering: - When the door opens, the door chime will alert you, so you don't have to worry about missing any customers. - You can install the door sensor on the door/window to alert you when children open the door/window, preventing them from sneaking out or encountering danger. When a thief is about to steal, you will receive a timely alert to protect your family and property. - The door sensor and receiver are already paired, making installation easy. Simply plug the receiver into a standard outlet, peel off the back of the tape that came with the door sensor (or fasten it with screws), and stick it to the door or window. - The door entry alert is equipped with 26 different ringtones and 5 adjustable volume levels, from silent to noisy (0-110 db), so you don't have to worry about not hearing the sound. - The acceptable range of 600Ft/182m is large enough to cover every door of a house or store. You can configure different bells for different sensors to know exactly which door or window was opened. - Amazon Logistics is SanJie's partner, and the company can quickly deliver the package to your home within 1-2 days. SanJie also provides a 30-day refund service. If there are any quality issues with the door chimes, please feel free to contact the company to ensure the best shopping and user experience.
