From the inventors of the modern doorbell, the NuTone Knock allows homeowners to see and speak with visitors from anywhere in the world.
Always know when someone is at your door – whether they ring the doorbell or not – with motion detection that works day or night. Easily adjust the Motion Detection Region and Sensitivity to customize alert settings and prevent false motion alerts. The 180 degree camera guarantees there are no blind spots and 720p HD video was specifically chosen to let you see all the important details without the lag time of other major brands.
Feel confident that your doorbell can withstand the most extreme weather conditions, whether you experience brutal winters in the Upper Midwest or hot, dry summers in the Arizona desert. NuTone Knock is weatherproof, with a rating of IP65, to protect from dust and water. In fact, NuTone Knock has been tested to withstand a water jet sprayed on it from any angle! NuTone Knock does not require a battery allowing it to operate reliably from -22F to 122F.
Simply connect the NuTone Knock your existing doorbell wiring. With built-in voltage detection and extended Wi-Fi range, the Nutone Knock can be installed in just minutes. No need to track down and replace hidden transformers. If the voltage detector identifies that your voltage is too low to run both the Chime and Smart Video Doorbell, simply add the Nutone plug in Wi-Fi chime (LA227WH).

Optional in-app purchase of cloud storage service (only $2-$4 monthly based on subscription level) allows videos to be automatically saved in the cloud whenever motion is detected or the button is pressed. Compatible with iOS and Android devices. Requires a Wi-Fi connection.
