This whitepaper explains how modern surveillance design aligns with IEC 62676-4:2025, introducing updated operational requirements such as overview, discern, characterize, and scrutinize. It presents the pixel density model, which links required image detail to camera resolution using pixels per meter based on human face width. Higher pixel densities enable deeper identification, from simple detection to high-certainty recognition. The paper emphasizes that while pixel density is a useful guideline, real-world performance is influenced by factors such as lighting, optics, and compression. Using advanced planning tools that incorporate these variables allows organizations to optimize camera placement and ensure the right balance between cost, coverage, and forensic detail.
