Sorry to hear about this happening, @MaxB. If your device was recently damaged and is not not working suddenly, this may require a closer look form our support team. Bringing your Doorbell indoors nearest the router, and charging it fully (if battery-powered), will help you test whether the video concern is connection or power related. You can perform a reset on your Video Doorbell by holding the setup button for 20 seconds, to see if this might improve operation.
If not, please give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support.
