Watchful OS is a physical security management platform designed for security teams, guards, and law enforcement. The system integrates with existing CCTV cameras, network video recorders (NVR), video management systems (VMS), sensors, and access control systems to provide centralized monitoring and management. The platform connects to various camera manufacturers and security infrastructure, allowing organizations to consolidate their physical security data sources. Users can configure automated security rules based on specific threat scenarios, unusual activity patterns, or custom conditions. The system evaluates events using its "Quill" evaluation engine, which can classify incidents based on multiple data inputs such as movement detection combined with access card validation. Watchful OS provides a review interface that displays potential security incidents with classifications such as "Potential Intruder" or "Possibly Staff" along with timestamps and location information. The platform supports workflow management for security operations and enables automated monitoring of properties. The system is positioned as a work management solution for crime fighting teams, offering data source management, workflow configuration, and rule-based automation for physical security operations.
