In some implementations, when face recognition is implemented locally, it is simplified according to local computational capability available at the doorbell camera 106. As a result of the facial recognition, the push notification is sent to the client device 220 indicating whether a known person has been recognized or a visitor is an unrecognizable person e. g. , a stranger. In some implementations, face recognition is only conducted after a user press on the doorbell button is detected. Alternatively, in some implementations, face recognition is conducted before a user press on the doorbell button, and triggers a process to monitor and detect the user press on the doorbell button.
