Wireless doorbell systems have come a long way in recent years. They allow you the ability to speak with visitors via an intercom, and most now come with HD video, and door buzzer app that allow you to see and communicate with guests with your smartphone or tablet, and open the door if you want.
Door buzzer systems alert you when someone buzzes your home or business. You can see exactly who is at your door, talk to them before letting them in, and you can even control access when you combine wireless video doorbell systems with a electric door strike.
