AI-powered video analytics for law enforcement, urban security, and large-scale video data analysis
Tevian solutions help law enforcement agencies and Safe City programs automate investigative and monitoring tasks. The platform enables video-based search, identification of relationships between people and vehicles, perimeter control, and analysis of large video streams. The solution is scalable and integrates with existing government and municipal IT systems.
Face Recognition
Real-time and forensic identification of individuals in live video and archives
The system delivers high-accuracy face recognition in dense crowds and under challenging camera angles. Detected faces are automatically matched against watchlists and investigation databases. Both real-time monitoring and retrospective archive search are supported.
What does the system provide:
- ●Instant identification: Automatic real-time matching of detected faces against watchlists.
- ●Deep archive search: Processing of petabyte-scale video archives for investigations and forensic analysis.
Search by attributes
Searching for individuals without photos using appearance descriptions
The solution is designed for cases where no photograph is available or image quality is insufficient. Search is performed using attributes such as gender, age, clothing, accessories, posture, and gait. Cross-camera tracking enables reconstruction of a person’s movement across locations.
What does the system provide:
- ●Effective investigation without reference photos
- ●Cross-camera tracking across complex camera networks
- ●Detailed recognition of clothing and appearance features
License Plate Recognition
Monitoring and analysis of vehicle movements
The system automatically recognizes vehicle license plates from multiple countries. A centralized database of vehicle movements is created.
What does the system provide:
- ●Movement history by vehicle plate number.
- ●Detection of wanted or suspicious vehicles.
- ●Traffic flow analysis.
Vehicle Search
Identification of vehicles based on visual characteristics
Enables vehicle search without knowing the license plate number. Used to locate stolen vehicles or vehicles involved in incidents.
What does the system provide:
- ●Search by multiple visual attributes.
- ●Fast filtering and analysis of large video archives.
Social Links Analysis
Identification of connections and interactions between individuals
The analytical module identifies relationships based on co-occurrence in video footage and meetings across locations.
What does the system provide:
- ●Visualization of contact networks.
- ●Spatiotemporal correlation analysis.
- ●Analytical support accelerating investigations.
Crowd Monitoring
People counting and crowd density control
A module designed for public event management and urban safety. It estimates crowd size in real time and helps proactively detect anomalies and risks.
What does the system provide:
- ●Crowd density heatmaps
- ●Accurate people counting at public events
Vehicle Reidentification
Tracking vehicles without license plates
Tracks vehicles across cameras even when license plates are hidden or obscured.
What does the system provide:
- ●Tracking vehicles with obscured plates.
- ●Full route reconstruction.
- ●Effective operation in sparse camera networks.
