emza is bringing a unique extremely efficient technology of Machine Learning based Computer Vision. This technology is the basis for our always-on intelligent visual sensors that operate for years on small batteries. Our proprietary Machine Learning system allows the sensors to be re-trained for practically any application. Our Computer Vision algorithms require a fraction of the memory and CPU power typically needed for such algorithms. Integrating the algorithms with custom made CMOS sensors and extremely lean processors yields a sub 1mW, coin-sized IoT sensor, that can detect and classify humans (or any other object), count people, perform queue monitoring and describe the observed activity.
