When it comes to license plate recognition (LPR) cameras, toll road applications and parking/access control systems serve distinct purposes and face unique challenges. Inex IZA800 family of toll road cameras and IZA500 family of parking and access control cameras may appear similar, but their design and functionality are optimized for very different environments. This article explores the key differences, helping you understand how these cameras meet the specific needs of toll roads and parking systems.
Key Similarities of Toll Road and Parking Cameras
- All-in-One Design: Both IZA800 and IZA500 cameras integrate LPR algorithms directly into the camera hardware. This all-in-one approach ensures real-time processing and eliminates the need for external computing systems.
- High-Resolution Sensors: Both camera types feature high-resolution sensors capable of capturing detailed images of license plates within a single lane of traffic.
- Flexible Operation Modes: The cameras support both triggered, non-triggered modes and hybrid modes, enabling versatile deployment based on site-specific requirements.
- Ability to Read All Types of Plates: Both camera families employ multi-spectral imaging technology, capturing license plates in visible and near-infrared (IR) wavelengths. This ensures dependable performance for a wide range of plate types, including reflective, non-reflective, legacy, and temporary license plates. The advanced imaging capability guarantees accurate reads regardless of plate material or environmental conditions.
While these similarities demonstrate shared strengths, the differences in their design and functionality are tailored to the distinct needs of toll roads and parking/access control systems.
Hardware Differences in Toll Road and Parking Cameras
- Built-in and External Illumination: Both camera families include built-in illumination, but toll road cameras often require additional external strobe illuminators. These ensure optimal performance in challenging conditions, such as high-speed traffic at night or glare from direct sunlight. Parking cameras rely solely on their built-in illuminators, which are sufficient for slower-moving vehicles in controlled lighting environments.
- Global Shutter vs. Rolling Shutter Sensors: Toll road cameras exclusively use global shutter sensors to eliminate motion blur, ensuring clear images of vehicles moving at high speeds. Parking cameras, which deal with slow traffic, may use one or both rolling shutter sensors without any loss in performance.
- Extreme Lighting Adaptability: Toll road cameras excel in handling extreme lighting conditions, such as direct sunlight reflecting off license plates. While still important, this level of adaptability is less critical for parking cameras, which usually operate in more predictable lighting scenarios.
Software Features in Toll Road vs. Parking Cameras
- Processing Speed and Efficiency: Parking cameras prioritize ultra-fast processing to avoid delays at entry and exit points, delivering license plate reads within fractions of a second. Toll road cameras handle more complex tasks such as integrating with toll road management systems which do not require real-time processing.
- Continuous Traffic Flow: Toll road cameras are designed to handle high-speed, continuous traffic flow, processing several vehicles per second. Parking systems, in contrast, manage one vehicle at a time, focusing on controlled access.
- Transaction Logging and Redundancy: Sophisticated transaction logging is a key feature of toll road cameras, ensuring no data is lost. This prevents missed toll transactions, which can otherwise lead to revenue loss or delayed error detection. Parking cameras require less complex logging mechanisms since errors are addressed in real-time.
- Custom vs. Standardized APIs: Parking cameras are built to integrate with standardized APIs from parking management or access control systems, ensuring seamless compatibility. Toll road cameras, however, often require custom APIs tailored to the unique specifications of each toll system.
Conclusion
Toll road and parking cameras share advanced technology but are engineered to meet very different operational needs. Inex’s IZA800 and IZA500 cameras deliver exceptional performance, whether managing fast-moving highway traffic or ensuring smooth access in parking facilities.
