Quadcopters with cameras are now at their peakpopularity: courier services use them to deliver goods, the military uses them to protect borders or for reconnaissance, and bloggers use them to take fantastic photos from a bird's eye view. Sunflower Labs also decided to use them in a rather unusual way - to protect homes.Just imagine.It's a dark evening, there's no one on the street, and you're sitting at home in a cozy armchair reading your favorite book. And suddenly there's a loud crunch outside the window. What is it? A dog, a cat, or enemies? You need to check, but you can't go yourself! You can send a drone that will transmit an image of what's happening right now in your yard or on the property near your house to your smartphone screen. And the "smart home" concept offers much broader functionality. There are lights with sensors around the perimeter of the property that monitor everything that happens. If something unusual happens, the system sends a notification to the owner of the property and launches a quadcopter to the scene. There, it turns on the camera and automatically starts a live broadcast to your phone. Thus, even if you are on the other side of the world on a business trip or honeymoon, you will always know what is happening near your front door or who climbed over the fence in the night.
