Visibility and Security – whether you're home or away

No more wondering "Who's there?" No more guessing if the children get home safely from school, or whether the mailman delivered your package. NuTone Knock lets you know when someone is at your door. The motion-sensing camera works day or night, so you never miss another visitor. You can even speak to anyone who rings the doorbell from anywhere in the world – with the convenience of your smartphone or tablet. The Do Not Disturb feature lets you set quiet hours for family time, movie time or naptime.

Ideal for challenging weather conditions, NuTone Knock can handle the sweltering heat of the desert or the extreme cold of the upper Midwest. With an IP65 rating to protect against dust and water, it is more dependable than other leading brands. NuTone Knock works with a home's existing doorbell wiring and installs in minutes.
