This is often done by companies that hold hazardous chemicals in storage, and that have things that can be taken. Medicine is placed in a separate area when it comes to pharmacy, this helps to reduce the risk of drugs being stolen: Whenever the door is opened the chime is set in motion, and it alerts them of entry. The noise could be a loud external noise, or you could also choose for it to go off on certain computers and devices. It needs to alert only certain individuals.
You can as well decide who should get in and out of the building by using an intercom. The door chime will be used as a link for allowing people entry to the building. The intercom either calls the desk or an apartment and the receiver decides whether to buzz the person in. When the chime goes off it means that the door is open and that the person has been granted passage. This is especially common in large buildings and apartments. It helps with order in the buildings and prevents many people from accessing the buildings all the time. There is, of course, a system of using an entrance code, that allows the people who work there to enter without asking for permission.

It might be that the best door chime is one that goes off when the door is open. Its not the ideal choice because it can become disorderly. Some door chime systems allow you to turn them off and on. This allows the receptionist to turn it off when they have gone on a break and are away from the desk. You can also set up such chimes on a timer so that it turns on at a particular time of the day. This helps to keep the people inside safe when the receptionist has gone.
