The Comelit 4680 A/V Module with B/W Camera (Ikall Series) delivers integrated audio-visual capability for access control and intercom applications, combining a compact form factor with reliable black-and-white imaging for entry monitoring and visitor verification.
This module is engineered as a Lock/Strike component within the Ikall ecosystem, supporting up to 120,000 concurrent users across networked installations. The black-and-white camera provides dependable image capture in varied lighting conditions, ideal for applications where clear facial recognition and entry documentation are required without the overhead of color processing. The fixed B/W sensor maintains consistent performance in low-light environments typical of building entrances, lobbies, and secure access points.
Dimensionally compact at 4.02" width × 2.17" height × 1.5" depth, the module integrates seamlessly into door frames, wall-mounted enclosures, and modular intercom installations. Its form factor accommodates retrofit and new-build deployments where space constraints or aesthetic requirements demand a slim profile. The rugged industrial construction suits both indoor and sheltered outdoor mounting scenarios common in multi-tenant buildings, gated communities, and commercial facilities.
Integration within the Comelit Ikall system leverages the platform's distributed architecture, enabling centralized management across multiple entry points. The Lock/Strike classification indicates direct compatibility with electric strike mechanisms and access control relay outputs, streamlining wiring and reducing auxiliary component count. This modular approach supports phased expansion—operators can deploy units incrementally and manage them through a unified dashboard, simplifying administrative overhead for facilities managing dozens of entrances.
The 120,000-user capacity supports enterprise-scale multi-site deployments, making the module suitable for large commercial campuses, hospitality chains, and government installations where credential management and audit logging span thousands of personnel. Each A/V transaction is logged within the Ikall framework, creating an auditable record of access attempts and visitor interactions.
Key technical highlights include:

The Comelit 4680 is purpose-built for facilities operators who need straightforward A/V entry verification without overcomplicating their infrastructure. The B/W camera and integrated lock strike control eliminate the need for separate cameras and relay modules at each door. At this scale (120,000 users), it's positioned for multi-building accounts; verify your facility count and credential load before ordering to ensure the Ikall platform's management layer aligns with your audit and reporting workflows.
