The doorbell will activate its sensor to detect motion, and when motion is captured, it will record videos on an average of about 10 seconds. The videos recorded will be uploaded and saved in the home base memory or in the cloud if the cloud service is activated. (The recording time on doorbell can not be extended)
It is the most important function of our all devices since it relates to motion detection. All of our Aosu devices have motion detection function and the settings are almost the same, also, and some of our other devices will be a little different, but most are the same.
Here are settings of motion detection. Go to the app, Settings-Motion Detection.
