Such systems, devices, and methods optionally complement or replace conventional systems, devices, and methods for illuminating, capturing, and analyzing scenes. The present disclosure describes compact doorbell camera implementations having capabilities of high power on camera processing, low light e. g. , night time illumination, concurrent transmission of multiple HD video streams, and wirelessly communication with other devices over multiple protocols e. g. , Wi Fi, Bluetooth, and IEEE 802. 15. 4. Such a doorbell camera also complements, replaces and/or expands conventional doorbell functions based on these processing and communication capabilities. The doorbell camera is mounted on or in proximity to a doorframe where a conventional doorbell may be mounted, and is electrically coupled to a power supply that may have been used to power the conventional doorbell. Specifically, the doorbell camera has one or more of a speaker, a microphone, a lens assembly, an image sensor, a waterproof device housing, a waterproof button assembly, light emitting diodes LEDs, infrared IR illuminators, a rechargeable battery and corresponding compensation circuit, an adjustable mounting plate, antennas and transceivers, a processor, and memory storing programs executed by the processor.
