modern corridor 3d model

Create a clean synthetic privacy-sensitive entrance corridor for a CCTV technology demo. The scene should resemble a modern anonymous building entrance where a caregiver and child could pass through, with neutral grey matte walls, darker matte floor, soft overhead lighting, a plain doorway in the distance, and subtle CCTV monitoring atmosphere. The style should match a realistic but fully synthetic licensing demo: calm, professional, technically refined, not sci-fi, not cartoonish. Include space for a small ceiling CCTV camera and a wall-mounted edge module, but no people in this asset. No real place, no logos, no signage, no text, no numbers, no school, hospital, airport, station, brand, dashboard, source code, formulas, or readable labels.
