Your video doorbell can be onboarded on a 2.4GHz or 5GHz Wi-Fi network. During setup, connect your doorbell to the same Wi-Fi network as your phone.

For devices/customers in Canada: 5GHz networks will have limitations in Canada due to Industry Canada (IC) regulations; 3 of the 4 bands need to be disabled, as a result you may experience connectivity issues on the 5GHz frequency.

What is the aspect ratio of the video doorbell's image?

Your video doorbell captures visitors from head to toe with an aspect ratio of 9:16 in vertical view.
