g. , a rainfall, a snowstorm and direct sun exposure, and require additional power supplies being physically routed to them even though these smart device normally can communicate data with a remote server or a client device wirelessly via one or more communication networks. Each outdoor smart device must be configured to attach firmly to a surface in the outdoor environment, have an access to a power supply source, function reliably under various severe weather conditions e. g. , water intrusion from a rainfall or snowstorm that could happen, and last for a long duration in the outdoor environment. As such, there is a need to mechanically mount a smart device to an outdoor surface in a compact and robust manner and with a convenient access to a power supply source, while incorporating into the smart device some resistance mechanisms against potential severe weather conditions. Accordingly, there is a need for systems and/or devices with more efficient, accurate, and effective methods for mounting, powering and operating a smart electronic device in an outdoor environment. A convenient and efficient approach is to integrate the smart electronic device into an existing outdoor electronic device, such that the smart electronic device can take advantage of existing infrastructures of the outdoor electronic device for mounting, powering and operating the smart electronic device. For example, a camera module can be integrated with a doorbell device, providing its functions of illuminating, capturing, and analyzing scenes, among other things in addition to doorbell functions. 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.
