The Hik DS-2CD1043G2-LIU was NOT defective. An earlier wiki entry wrongly
concluded it needed RMA (dead event engine) based on a silent alertStream
+ diskfull/EventScribe:except + dead RTC surviving a full factory reset.
Real cause: no detection AREA was drawn on the frame. With no region, the
camera detects nothing -> generates no event -> posts nothing. The instant
an area was drawn, the first vehicle produced a clean POST.
- Flag "draw the detection area" as the FIRST thing to check.
- Document the confirmed real payload: multipart/form-data (MoveDetection.xml),
EventNotificationAlert with eventType=VMD, eventState=active,
targetType=vehicle (vehicle/human classified on-device), targetRect bbox.
Note the dateTime is garbage (dead RTC) -> use our own receive time.
- Reframe the SSH diagnostics: diskfull/EventScribe/RTC are RED HERRINGS,
not proof of a dead camera; don't escalate to hardware fault while a basic
config precondition is unmet.
- Append a log correction (append-only) superseding the earlier conclusion.
