Processing pipeline: decode video stream, run inference (object detection, tracking), generate events/metadata, optionally store video clips. Hardware: NVIDIA Jetson for AI inference, Intel OpenVINO for optimization. Privacy benefits: faces blurred or not transmitted, only anonymous statistics sent to cloud. Hybrid approach: edge handles real-time, cloud handles retraining and complex queries.
This is an advanced topic that goes beyond the core material, but understanding it will give you a deeper appreciation of the subject. Researchers continue to study this area, and new discoveries are being made all the time.
Did You Know? A single 4K camera generates 15 TB of data per day—edge processing reduces this to kilobytes of insights!
