Developed for smart IoT mobility solutions:
CARRIDA enables MQTT and LPR-based travel time measurement

CARRIDA Technologies, provider of leading LPR software solutions, has released version 4.8 of its CARRIDA Edge LPR software and an extensive update to the CARRIDA SDK engine. CARRIDA Edge now supports MQTT to publish reading results and images and thus enables the integration with IoT devices and networks. In addition, the hashing of license plate strings for fully anonymized storage and transmission is now supported in CARRIDA SDK 4.7. This makes the software a perfect choice to setup solutions with LPR-based travel time measurement for smart mobility, traffic management, tolling, enforcement and many more data-driven applications.

The LPR engine can be flexibly deployed as OEM library, web solution for easy setup and configuration of edge devices, or with the CARRIDA App for any Android device. On top, CARRIDA offers validated platforms and components for easy, quick and cost-effective developments of individual LPR applications.

CARRIDA Edge 4.8 offers support for MQTT as well as an improved display of LPR results, among other new features.

With CARRIDA Edge 4.8, MQTT publishing features have been added and enable the configuration of one or more MQTT servers. Devices using the Software engine can thus be easily integrated in IoT networks and can securely transfer data to other devices. Data security has also been improved with public key authentication for FTP actions and certificate based authentication for HTTP data transfer. The LPR server is now even more robust and reliable and the Video4Linux (v4l2) camera handling has also been improved.

The WebGUI for easy setup of edge devices comes with enhanced features in CARRIDA Edge 4.8. Configuration of parameters is now much more efficient and faster, and the design of result visualizations has been improved. Also, statistics of the edge devices’ operation and further information is now available in the WebGUI.

CARRIDA Edge is based on the CARRIDA SDK engine, which is now released in version 4.7. This update also provides major changes, such as new license plate verification features for a better suppression of unwanted readings. Added parameters for state recognition improve reading results and enable even faster identification. As a newly introduced feature, the CARRIDA engine now recognizes if vehicles are approaching, leaving or static, based on changes in size of the detected license plate.

CARRIDA Edge can optionally use securely hashed strings to transmit and store license plates, guaranteeing full anonymity of licence plate readings. Combined with MQTT data transmission, applications can measure time of travel for vehicles passing two or more cameras, all in compliance with highest data security standards. Both new software versions are available immediately.
