Requirements

Open ALPR Agent is the software developed by Rekor Systems, which is capable of analyzing video images for vehicle license plate detection and reading. As a requirement, the agent needs to be run on a workstation with recommended specifications, such as the latest generation Intel i5, to process approximately 20 frames per second of video at a resolution of 720p, allowing for the capture of license plates from vehicles moving at different speeds.

In other words, an agent can handle three cameras for low-speed vehicles, two cameras for medium-speed vehicles, and one camera for high-speed vehicles.

The Open ALPR agent maintains constant values for ROM and RAM memory consumption. Each analysis thread uses 500 MB of memory (CPU core). The agent stores JPEG images of recognized plates on the disk, but the required space depends on the number of detected plates.
