Quadrocopters with cameras are now at their peakpopularity: courier services use them to deliver goods, military - to protect borders or intelligence, and bloggers - to get fantastic photos from a bird's eye view. Sunflower Labs also decided to use them in a rather unusual way - for protection of housing. Just imagine.It is a dark evening, no one is on the street, and you are sitting at home in a comfortable armchair and reading your favorite book. And suddenly a loud crunch was heard outside the window. What's this? Dog, cat or enemies? You need to check, but do not go yourself! You can send a drone that will transmit to the smartphone screen an image of what is happening right now in your yard or in the area near your house. And the concept of "smart home" implies much broader functionality. Luminaires with sensors are located along the entire perimeter of the site, which monitor everything that happens. If something unusual happens, the system sends a notification to the landlord and launches the quadcopter to the scene. There, he turns on the camera and automatically starts broadcasting live to his phone. Thus, even if you are on a business trip or honeymoon on the other side of the world, you will always know what is happening near your front door or who climbed over the fence at night.
