Quickly turning your lights on and off via a physical switch

I read here https://support.ring.com/hc/en-au/articles/115004155866-Controlling-the-floodlights-and-light-settings-on-your-Floodlight-Cam

That “Quickly turning your lights on and off via a physical switch is actually a manual override and is a safety feature of any brand of floodlight, not just the Floodlight Cam.”

What exactly does this refer to?

Hi @mandkring. Since the Ring Floodlight Cam can be hardwired into your homes electrical circuit, it is possible to add a light switch into this circuit. Flipping the light switch on or off, can cut power to the Floodlight Cam.
