Is there a minimum distance and height to place the camera for optimal ALPR?#

Yes! Please refer to our article on Camera Set Up for Best ALPR.

Does the color of the image or video/camera feed impact ALPR accuracy?#

Yes, from our experience, both Snapshot and Stream ALPR engines perform better with color images rather than black and white images.

Yes! Our Vehicle Make, Model and Color dataset is derived from over 9,000 vehicle make models sold globally.

What does this error message mean: “Your account status has not been checked in the past 30 days. An Internet connection is required.”?#

For our Subscription services, our software sends a few bytes of data each month to validate the subscription. For added clarity, we do not send any images back from the on-premise version of Snapshot, Stream and ParkPow.

To resolve this issue, just make sure that the machine has some (intermittent OK) Internet access or a private VPN to our servers to validate the subscription.

How come Plate Recognizer is not able to correctly read this license plate?#

Our service offers great ALPR accuracy but it won’t work in all cases.

As a rule of thumb if a human can read the plate, then our ALPR engine should be able to as well. If a human can squint and read most of the plate except for maybe a character or two, then there’s a decent chance that our ALPR engine can decode it. However, if a human has a really hard time reading the license plate, then Plate Recognizer may not be able to read it correctly.

If you repeatedly get a few characters of the plate decoded incorrectly, please double check the Region ID. Please refer to Plate Recognizer API Docs for all the region codes.

Also, please share a few images with us via email so we can take a look.

Is Plate Recognizer ALPR software GDPR compliant?#

Yes. Our On-Premise SDK can run on your hardware in your IT environment. Snapshot SDK processes all images on site and Stream processes all video/camera feeds on site. Both products do not need an Internet connection to work.

Please read more about Plate Recognizer GDPR compliance.

How is Plate Recognizer better than an open source OCR solution?#

Our Plate Recognizer core plate detection and plate decoding algorithms are far superior to plain OCR solutions. Further, we have added a number of enhancements in our ALPR solution to take into account various real-life situations, such as blurry images, diverse lighting conditions, low resolution, images with vehicles taken from the side, etc.
