Just this morning the Bulb Cam outside my garage door captured a pair of people in hoodies walking down the street with flashlights. One of them walked up on the driveway and began to shine his light into the bed of the pickup parked there, and then Bulb Cam and its paired Accessory Bulbs brightened from 40% Ambient Light to 100% based on Person detection, and this person immediately changed direction and increased pace to walk away. I really like those features in these products.
