Three new Node-RED trigger nodes in BetterFrame Triggers palette:
bf-trigger-motion (red) — fires on MotionAlarm, CellMotionDetector,
VideoAnalytics/Motion, FieldDetector topics. Outputs msg.active
(true/false) for motion start/stop. Camera ID filter optional.
bf-trigger-anpr (blue) — fires on LicensePlateRecognition, Plate,
ANPR, LPR, NumberPlate topics. Extracts msg.plate (string) and
msg.confidence (number) from vendor-specific payload fields
(Hikvision PlateNumber, Dahua plateNumber, etc.). Camera ID filter.
bf-trigger-event (green) — generic catch-all. Topic substring filter
+ camera ID filter. Outputs msg.source + msg.data as key-value objects
parsed from ONVIF SimpleItems. Use for line crossing, intrusion,
digital input, tamper, audio detection, or any unknown topic.
Server side: ONVIF events (source_type=onvif) now additionally forward
to the fixed onvif.event route so all three nodes receive events without
needing per-topic Node-RED route registration.
