Smart doorbells without a subscription store camera footage on a memory card or on an included base station. You can watch footage and download it via the app on your smartphone. Because you store the footage locally, you don't have to depend on an online cloud service from the manufacturer. You don't have to pay any monthly subscription costs either. With some smart doorbells, the memory card isn't included in the packaging. Make sure to check if it's included with a smart doorbell with local storage.
