When it comes to knowing whos at your door before you actually open it， theres nothing better than a video doorbell. After all， peepholes can get smudged， wet， and physically blocked， which means you may not know whos on the other side. Is it a relative， your neighbor， the pizza delivery guy， or a total stranger？

A video doorbell eliminates （消除） these possibilities， helping you feel more secure in your home. Regardless of whether or not youre at home， youll be able to see whos come and even hear and talk to the person standing on your doorstep.

Recently， the number of thieves has been increasing in Singapore. One easy way to safeguard against property theft， home invasion （入侵）， porch pirates （海盗）， and even unwanted solicitors is to identify who is at your doorstep before opening your door.

Enter the video doorbell， a first line of defense for homeowners that not only lets you see and speak with whoever is outside， but will also record footage （片段） of visitors that approach your door while youre away or unable to answer. Its called the Video Doorbell—a smart doorbell that notifies（通知） homeowners when they have company. That is to say， it doesnt just notify with the ring of a bell. Unlike a traditional doorbell， it can send push notifications directly to your phone—whether youre home or away—acts like a surveillance camera so you can view activity outside your door， and has a two⁃way talk feature that allows you to interact with visitors.

The video doorbell camera works by allowing you to view live video of whoever is outside your door， without having to open the door， move a curtain or peep through a window... This allows you to discreetly （谨慎地） view who is at the door without making your presence known！ Not only does this make it possible to screen your door visitors the same way caller ID works for your phone calls， but you also dont have to let a stranger or a potential intruder （闯入者） know you are home.

Which of the following will make the traditional peephole lose its function？

A.The property theft.

B.Strangers at your doorstep.

C.The pizza delivery guy.

D.An intentional block.
