We collaborated with BDTI and TryoLabs to create MaskCam, a real-world 

demo showcasing the NVIDIA Jetson Nano’s deep learning capabilities.



EJ Technology Consultants was contracted by BDTI, a technology development and evaluation firm that specializes in embedded computer vision applications, to assist with evaluating the NVIDIA Jetson Nano’s suitability to real-world edge AI applications. The demo was a mask  detection smart camera that we developed from an initial concept into a production-ready prototype. A video showing MaskCam in action is available on our YouTube channel.


MaskCam utilizes NVIDIA’s TensorRT library to implement a high-speed vision pipeline that runs live camera frames through a YOLOv4-tiny model trained to detect masked and unmasked faces. The optimized pipeline runs at 14FPS on the Jetson Nano. The program reports mask wearing statistics  to a web server and saves recorded video if the number of unmasked faces is above a certain threshold.



EJ Technology Consultants contributed to the system design of the smart camera:


  • Wrote top-level system requirements and product specifications

  • Evaluated and selected hardware that met specifications while maintaining a low cost target

  • Integrated hardware drivers with embedded Linux operating system and troubleshot  software/firmware where necessary

  • Performed system testing



We collaborated with a cross-functional team of software, DevOps, and production engineers from TryoLabs, BDTI, and Jabil during the development process. We also presented with BDTI and Tryolabs at the NVIDIA GTC and Embedded Vision Summit conferences.
