Add on porch light cam

it’d be awesome to have an add on cam for my existing porch or garage lights! I picture a device that taps into power of existing lights and can hang below, on side or above them…almost as if they belong together. So essentially u can use a fixture of your choice and add a camera to any of them.
It can be sleek, small and inconspicuous.

Would love to switch to Ring from my current solution, but will not until Ring provides a porch light security camera product. Porch light security cameras make so much sense as they provide constant power, easy install, integrated lighting, and are aesthetically pleasing (Ring flood lights and spot cams are just plain ugly and stick out like a sore thumb).
