Survision License Plate Recognition technology combines OCR and Neural Networks to make our cameras “optically” read a vehicle’s license plate and transform the graphic data into digital information in real-time (20ms).
We took the heavy LPR servers away from the equation by providing our cameras with an AI-powered firmware to do the most challenging part of the job.
Why do we do that?
Our cameras don't need any physical device to activate the LPR process; they constantly scan for license plates on the fly; this is called No Trigger Mode. Survision LPR cameras are ideal for triggerless systems such as ticketless parking, free-flow tolling, etc.
Our cameras can also be activated by an external device (Classic Trigger Mode), just like any other camera in the market.
Our goal is to get rid of the physical triggers for good and save lots of money in infrastructure, but we know sometimes they are still needed; that is why our cameras cover the whole spectrum of possible scenarios.
LPR cameras are often part of a more complex environment in which LPR data interacts with other information (databases or events) in the whole decision-making algorithm. Survision LPR cameras have their SDK for communicating with your system and to be programmatically triggered (after checking on the database, after ticket retrieval, before opening barrier, etc.).
This feature is called software trigger and makes our cameras the ideal companion to intelligent solutions in Access Control, tolling, Security, Parking or smart cities.
In cases such as tolling, vehicles can go as fast as 250 km/h (155 mph); reading plates in these scenarios is achievable by high-speed LPR cameras; that is why Survision has focused on building LPR cameras capable of reading and processing license plates in only 20 milliseconds!
This opens a whole world of possibilities when thinking about barrierless, gateless, or ticketless operations by allowing vehicles to ”just keep going” with no speed reduction at all.
Survision LPR cameras can provide additional information for each reading:
Photo (JPEG) of the License Plate: Survision LPR cameras supply a JPEG of the plate for real-time and later manual verifications.
Continuous, real-time video flow: used for security matters and a better understanding of installation and setting issues.
Confidence ratio: Our cameras self-evaluate the probability that the plate was correctly read, helpful to decide whether a license plate has to be automatically processed or not.
Country and state: These are critical contextual identification elements for some countries or states sharing the same license plate syntax rules.
Direction (of movement): It helps the system eliminate counting or synchronization issues and helps drivers get noticed when going in the wrong direction.
Vehicle Speed: For informational or pedagogical purposes, public display of driving speed has been proved as a speed reduction method.
Independent from any weather condition or external artificial lighting, Survision LPR cameras have their own illumination source:
Shutter synchronized and automatically adjusted: Light powers on only when necessary; this enhances the LED’s lifespan, reduces heat, power consumption, and harmfulness.
Survision LPR cameras automatically adapt their lighting parameters to consider the surrounding lighting changes and maintain a clear image.
The right wavelength: All Survision LPR cameras are available in White Light, best for colored characters or 850nm infrared (IR) light for black characters.
Survision LPR cameras are built to do one job only: Read license plates.
Twenty-one years looking up to build an All-in-one camera that contains filming, processing and protecting components; cheaper and easier to install.
Survision cameras can resist as cold as -40°C / °F and hot as +55 °C / 131 °F
The secret for the perfect long-lasting LPR camera relies on the right hardware:
