A professional, no modern 3D logo for "OPTIGUARD," centered on a dark, textured matte grey background. The central element is a detailed, realistic white bullet-style CCTV camera, angled forward and to the right, mounted within a polished three-dimensional circular frame. This frame is segmented, featuring a vibrant blue arc on the upper-left and a brushed silver-grey section on the right. The camera body itself is white with dark lens elements and details, and clearly displays the text "OptiGuard" in a clean, dark sans-serif font on its side. The camera is integrated with the frame via a subtle curved stand. Below the main circular emblem, the word "OPTIGUARD" is rendered in large, bold, metallic silver-grey 3D capital letters, casting a soft shadow on the background. The entire logo hasno realistic 3D depth, metallic and matte finishes, and professional studio lighting creating defined highlights and no shadows. The composition is clean, centered, and high-resolution. Aspect Ratio 1:1.
