My Security Cameras Were Dead for 3 Days. Now They Fix Themselves.

I run three AI-powered security cameras at home. RTSP streams feed into a Python daemon that runs OpenCV contour detection, sends cropped regions to a vision LLM on an NVIDIA DGX Spark, and fires WhatsApp alerts when it spots something. It works great — until it doesn't. On April 13th, the cameras silently died. No alerts. No crash. No logs. The process was "running." launchctl showed a healthy PID. The dashboard showed the last captured frame — frozen, three days old. Nobody noticed until April
