1. About the doorbell camera, Usually in standby mode, the host is in sleep state. Therefore, you cannot use the APP to actively access the camera. When the doorbell button of the host is pressed, the host will enter the working state and make a video call to the APP.
2. The cloud storage services are not free. But the doorbell can capture pictures to your mobile APP for free.
3. When you install the Kement APP, Please check your phone system settings and make sure all the permissions are enable. Including notification management in mobile phone settings, and application permission management. this is very important!
4. About the Android mobile phone, if the Kement APP can not receive the doorbell message in time when someone press the doorbell. It may be because of the Android system version is too low, or maybe the phone memory capacity is insufficient, which will cause the Kement APP fail connect to the Internet when the screen is locked. Please know it before make purchase.
