Sigmoid-LPR automatic license plate recognition

We offer license plate recognition systems for a broad set of applications, on a broad set of devices and platforms. Our set of stock applications includes:

• surveillance systems for villages / towns,

• gate control/fee calculation for parking places,

• in-car and handheld mobile devices for police and security.

Among the license plate recognition core, our applications include a rich set of features, like query log with filtering, export, import and statistics capabilities, stream formats (MxPEG, MJPEG, H264, H265 etc) support of input and output devices, various possibilities to send and receive data to/from other software, and access to various remote license plate databases, for example the official on-line Hungarian national car database. (This specific program module was certified by the Hungarian Ministry of Justice and Law Enforcement.)

Sigmoid offers client-server applications which makes it possible to use and to administer the recognition server from distant sites.

We also offer large systems by connecting the distributed recognition servers together, forming a unified multi level surveillance/access control system covering hundreds of cameras.

Using MOBOTIX can yield a 3-4% performance boost in recognition rate, thanks to its superior image quality over other brands. Our LPR engine uses handwritten optimized native MxPEG decoding since 2006. At that time it was the very first LPR solution for MOBOTIX cameras in the world. And we are very proud of it.
