What is most important for 24 hour License Plate Recognition of fast moving cars?
Correct Answer: C
For 24-hour License Plate Recognition (LPR) of fast-moving cars, adequate illumination is crucial. Infrared (IR) light is essential because it allows for clear image capture in low light or nighttime conditions. IR light ensures that the camera can consistently capture high-quality images of license plates regardless of the time of day, which is vital for accurate LPR. PoE (Power over Ethernet), processing speed, and interlaced scanning are also important, but without IR light, the system cannot reliably operate 24 hours a day. This information is verified from Axis Communications' documentation on LPR systems and best practices for lighting.
