Generate a image CCTV-style surveillance footage capturing a stylish teenage girl walking past a security camera. She pauses, looks directly up into the lens with a bright, friendly smile, and waves her hand casually. Her movements are candid and natural, yet carrying a subtle, confident, model-like poise. She is wearing a casual, modern outfit, walking through an indoor public space such as a hallway or a lobby. The shot is captured from a high-angle security camera perspective utilizing a slightly distorted wide-angle lens. The visual quality is intentionally low-resolution and desaturated, nearly monochrome, to mimic authentic security footage. A digital timestamp overlay ticks in the corner, while subtle scan lines, digital noise, and heavy compression artifacts overlay the video. There is realistic motion blur on her wave, uneven lighting across the space, and harsh shadows. The entire frame has a grainy texture, embodying a raw, unpolished, and documentary-style surveillance aesthetic.
