Considerations For Implementing An LPR Camera System
LPR camera systems can vary in terms of features, capabilities, and quality. Therefore, it is important to look for the following aspects when buying or choosing an LPR camera system:
LPR camera systems should have high-resolution cameras that can capture clear and sharp images of the license plates, even in low-light, high-speed, or wide-angle situations. The cameras should also have features such as infrared illumination, wide dynamic range, or image stabilization, to enhance the image quality and accuracy.
LPR camera systems should have advanced OCR software that can analyze and interpret the images and convert them into text, even in complex, noisy, or distorted situations. The software should also have features such as multiple plate reading, different format recognition, or different language support, to enhance the OCR accuracy and speed, to enhance the OCR performance and reliability.
LPR camera systems should have seamless integration with the database of license plates that the system compares the text with. The database should be updated, accurate, and secure, and the system should be able to access, query, and update the database in real time or near real time, depending on the application and network availability.
Some LPR camera systems fail to recognize characters correctly. It is better to look for cameras that return the best matches as opposed to exact ones even when an instance is not found in the database. Modern LPR systems “fuzzy match” characters to return the closest match even when characters are not recognized or captured properly.
Angle, Distance And Location
When installing LPR cameras, instead of having a large field of view, it is better to have a single “choke point”, which is a zoomed in area focused by the camera to return the highest quality image. This is specific to gated areas like parking lots, toll booths, drive-throughs where the vehicle passes through a specific pathway.
LPR camera systems should have reasonable and affordable costs for the owners or operators of the system, considering the initial investment, operational expenses, and maintenance fees. The system should also have features such as cloud storage, wireless connectivity, or solar power, to reduce the costs and increase the efficiency of the system.
