Abstract: Systems and methods provide a notification of a connectivity problem of a video doorbell to a smartphone. A first communication link between the video doorbell and a backend server is determined unavailable, such as when a password used by the video doorbell to access a local area network (LAN) is not accepted by the LAN.

Abstract: Managing operations associated with one or more voltage changes and one or more frequency changes. A voltage change request and a frequency change request are associated with dynamic voltage and frequency scaling (DVFS) operations. The DVFS operations are transmitted by the processors to be executed by one or more direct current assemblies.
