Cloud native motion detection microservice

This software implements the motion detection portion of well known motion-project as a microservice. For the tiling counterpart see camera-tiler repository.

In a nutshell:

• It brings the MJPEG stream into the cluster
• Performs highly optimal JPEG DCT coefficient based motion detection without actually decoding the JPEG frame to a bitmap
• Writes events to MongoDB
• Generates thumbnails based on JPEG DCT coefficents
• Uploads screenshots and corresponding thumbnails to S3
• Exposes endpoint for distributing MJPEG stream inside the cluster, eg for the camera-tiler
• Exposes endpoint for inspecting DCT blocks where motion has been detected

Developing

Bundled docker-compose.yml brings up:

• camdetect bypass stream
• camdetect debug
• Minio
• Mongoexpress
• Prometheus
• mjpeg-streamer

To manually trigger event:

docker kill -sUSR1 camera-motion-detect_camdetect_1
