Which technology is commonly used for license plate recognition in access control and parking management?

• A. CCTV cameras
• B. Video analytics
• C. License plate recognition
• D. Biometric readers

Answer: (C)

License plate recognition is the technology that automatically reads vehicle license plates from camera images. It works by locating the plate in a frame, enhancing the image, and using OCR to decode the characters, even in challenging conditions like glare, motion, or nighttime with infrared lighting. In access control and parking management, this capability is paired with gates or parking software to verify whether a plate is registered or permitted, log entries and exits, and enforce time or payment rules, enabling smooth, scalable, hands-free operation for many vehicles. While CCTV cameras provide the capture hardware, the actual recognition is done by LPR software; video analytics can include plate recognition as a feature but isn’t the specific technology by itself; biometric readers, on the other hand, read human identifiers and aren’t used for vehicle plates.
