- PTZ (Pan-Tilt-Zoom) Cameras: Move in multiple directions and zoom remotely, giving control centers the flexibility to follow incidents, track vehicles, or monitor specific areas in detail.
- Multi-Sensor Cameras: Combine multiple lenses in one housing to deliver wide, customizable coverage of large intersections without gaps, giving operators detailed visibility across several directions at once.
- Fixed Cameras: Maintain a consistent field of view, capturing reliable footage at critical points such as stoplights, crosswalks, or highway on-ramps where consistent coverage is essential.
- 360 Panoramic Cameras: Capture an ultra-wide field of view with a single device, reducing blind spots and providing full-scene awareness in complex or crowded intersections.
- Thermal Imaging Cameras: Detect heat signatures, allowing accurate detection of vehicles, cyclists, or pedestrians in poor visibility caused by fog, rain, or nighttime conditions.
2. Enforcement Cameras
- Speed Cameras (Radar or LIDAR-Based): Automatically detect vehicles traveling above legal limits and capture timestamped images for violation processing using radar or laser sensors.
- Average Speed (Section Control) Cameras: Calculate average vehicle speed between locations, promoting steady, compliant driving behavior.
- Red-light cameras: Detect and record vehicles that enter the junction after the signal changes, reducing crash risks and improving compliance.
- Stop sign cameras: Identify vehicles that roll through or fail to stop completely at intersections, helping law enforcement reduce collision risks in residential and rural areas.
- Seat belt and mobile phone detection cameras: Automatically flag drivers who are not wearing seatbelts or using mobile devices, utilizing AI-based recognition; these cameras promote safer driving habits.
- Bus lane / HOV lane cameras: Monitor occupancy and usage of designated lanes to ensure only authorized vehicles access priority routes.
- Toll enforcement cameras: Utilize high-resolution imaging and license plate recognition to facilitate accurate toll collection and violation detection, all while maintaining optimal traffic flow.
3. Automated License plate Recognition (ALPR/ANPR) Cameras Fixed ALPR Cameras
- Fixed ALPR Cameras: Mounts on poles or gantries to continuously scan license plates, matching data against law enforcement or tolling databases for fast identification.
- Mobile ALPR Cameras: Mounts on vehicles, allowing patrol cars to scan plates on the move, supporting real-time detection of stolen vehicles or outstanding violations.
- Covert ALPR Systems: Built for discreet operation, covert setups gather data in sensitive or high-security environments without alerting targets to their presence.
4. Smart / Intelligent Traffic Cameras
