Firstly, the TP-Link Tapo C420S2 is in a round-shaped design and at the front, you will find its two spotlights, a light sensor, status LED, motion sensor, and of course the camera’s lens. At the back of the camera, you will find a cover with a mounting hole and a USB charging port. Remove this cover by turning it anti-clockwise and you will find the camera’s battery compartment and a Sync/Reset button. Below the camera, you will also find the camera’s speaker and another mounting hole that enables you mount the camera on a table.
