Significant advancements in video monitoring standards underscore the evolving needs within the security sector. Last year, the International Electrotechnical Commission (IEC) released a major update to its monitoring standard, IEC 62676-4:2025, replacing the existing DORI framework with the more comprehensive OODPCVS classification.
This development reflects rapid advancements in digital imaging and analytics, which have necessitated more detailed and applicable classifications for security applications.
The new OODPCVS framework emerged in response to substantial shifts in technology since the DORI classification was introduced in 2014.
Developments include improvements in camera resolutions and the capabilities of AI-driven analytics, which demand more precise detail definitions. The DORI framework’s four levels—detection, observation, recognition, and identification—no longer sufficed for modern, complex monitoring needs. OODPCVS introduces seven distinct levels: overview, outline, discern, perceive, characterize, validate, and scrutinize.
Advances in video technology necessitated the update of classification standards. Camera resolution has significantly progressed, with current systems leveraging high-resolution, multi-sensor cameras that outperform previous technical assumptions.
Sophisticated AI analytics now require higher pixel densities for tasks such as facial recognition and vehicle plate identification. Diverse industry applications further fuelled the demand for refined image detail definitions across various complex scenarios.
The former DORI framework, detailed in IEC 62676-4:2014, included four image detail classifications: detection (25 px/m), observation (62 px/m), recognition (125 px/m), and identification (250 px/m). In contrast, OODPCVS provides more granularity with levels designed to accommodate specific operational needs. For instance, identifying a person or license plate now requires 500 px/m under the “Validate” level, as opposed to 250 px/m under DORI’s “Identification” level.
The implementation of the OODPCVS framework enhances operational effectiveness in video monitoring systems. It enables precise system planning, aligning camera deployments more closely to pixel density requirements for specific monitoring zones. This alignment improves AI performance by matching each task to its corresponding operation and pixel density level, enhancing overall reliability and system performance.
The new standard promotes a unified approach across the security sector, facilitating improved collaboration among manufacturers, integrators, and end users. This common framework reduces ambiguity in system design and execution, ensuring that all stakeholders work towards aligned objectives.
In response to these changes, Hikvision is updating its product specifications and design tools to align with the OODPCVS framework. These updates are intended to assist their partners in implementing solutions that meet contemporary standards while also supporting legacy systems. Hikvision remains dedicated to offering guidance and solutions that ensure compliance with new industry requirements, facilitating success in their partners’ security endeavours.
