Drone Monitoring in Concrete Structure: A drone equipped with a camera hovering above a concrete structure. The drone's body is black, and it features four propellers on each side, which are also black. A green light is visible at the center of the drone's front section, where the camera is mounted. The drone appears to be in motion, as indicated by the blurred background. In the background, a concrete structure with yellow lights can be seen. The overall impression of the image suggests that it was taken for monitoring purposes, possibly during nighttime or in low-light conditions.
