Architecture:

STM32 or i.MX RT processor (Low Latency), + Time-of-Flight (ToF) FPGA, all housed in a waterproof enclosure rated for depth to allow for the above use cases.

Connectivity:

Ethernet (via penetrator cables) or Optical Modem

Special Considerations for Underwater Ruggedized Cameras:

Thermal Management (using Aluminum Core PCBs), Use of Corrosion Resistant Connectors, and Lens Domes.

Reference Example:

Carnegie Mellon's Underwater ToF camera project utilizes custom two-layer FR4 PCB for LED drivers (for ToF Cameras) and uses Aluminum Core PCBs for thermal management. The underwater camera is housed in a waterproof enclosure with an acrylic lens dome.

Edge AI Camera (On-Device Intelligence)

Edge AI Cameras leverage onboard processing power to allow inference and decision-making at the time of capture and are mostly used in retail, traffic management, license plate recognition, and ensuring safety compliance.

An architecture would typically include:

  • An NVIDIA Jetson Nano/Orin processor or a Raspberry Pi and Google Coral processor or an ESP32-S3 with TensorFlow Lite.
  • AI models, such as YOLO (for detecting objects), FaceNet (for recognizing people), PaddleOCR (for reading text and license plates).
  • Real-time inference and metadata streaming using MQTT, with others having low bandwidth operations.
  • Utilizing powered devices from 5V to 12V, which is higher than the other architectures.

For example, a traffic camera that captures license plates, recognizes them locally, and sends only the license plate number and time to the cloud rather than sending all video, thereby saving 95% in bandwidth and 95% of the cost of that traffic camera in the cloud.
