A tiny stdlib HTTP server that logs every request (source IP, method, path, full body, JPEG part stripped) to verify whether a Hikvision camera actually POSTs its Alarm Server events — independent of our app's parsing/acceptance. It cracked the 2026-06-27 "auto-exit" investigation: proved the exit camera was sending NOTHING (corrupt config DB), then later that it sent plain VMD without targetType=vehicle. python3 test-post-camera-events.py [port] # default 8099 Point a camera's Alarm Server at this host:port; drive a car. A line from the camera IP = it sends (debug downstream); silence = the camera isn't POSTing. Claude-Session: https://claude.ai/code/session_01Xcm6ikLgGoCxxHrxtjkk5V
