A realistic security camera footage showing the front door of a suburban American house at night. The porch light flickers faintly, illuminating carved pumpkins and scattered autumn leaves. Suddenly, a large brown bear charges the door from outside and knocks it down, ripping the door off its hinges — there are creaks, splinters, and a heavy thud as the wood crashes against the frame. The bear steps inside with heavy, deliberate movements, sniffing the air and looking around cautiously but confidently; its fur glistens in the dim porch light. The camera stays fixed, capturing the whole sequence from a wide-angle perspective; a timestamp appears in the corner and the footage has the slightly grainy, low-light quality typical of real security cameras. The atmosphere is tense and believable — sounds of breaking wood, blowing leaves, and distant ambient noises — as if the moment were accidentally recorded by a home surveillance system.
