Baseus Security S2 Outdoor Camera 4K review: It sees the light

When you purchase through links in our articles, we may earn a small commission. A solar panel on a security cam is nothing new, but the panel on this one tracks the sun, rotating to gain maximum exposure. If you can mount it where it can harvest a steady supply of sunlight, the Baseus Security S2 Outdoor Camera 4K's tracking solar panel makes it one of the few outdoor cameras that can run truly unattended, capturing crisp 4K-resolution video as a bonus. For many households, outdoor cameras are the front line of home security. The devices watch over driveways, porches, and backyards, catching activity that doorbell cameras often miss.
