IPC HTTP POST Format (v2.1)

Verification of direct camera posts on v2.1 firmware is in progress. Until this section is complete, log the raw post body and check for messageType, the smartType spelling, and where the plate list result appears.

Cameras on v2.1 firmware report httpPostVersion 2.1.0. On a v2.1 LPR camera running 5.3.1 firmware, the HTTP POST V2 event list in the web interface is ALL, MOTION, SENSOR, AVD, and VEHICLE, and the data-type element is named subDataType. See httpPostV2 Data Types and Webhook Configuration.

V2 rows and the V1 sender

On LPR-IP4 firmware 5.3.1, saving a V2 (httpPostV2) row in the web interface also turned on the legacy V1 httpPost sender, aimed at the same host, port, and path. The page has no separate V1 switch. In testing with a V2 row saved for VEHICLE, every post received used the V1 layout: config version 1.7, no messageType on plate posts, and smartType VEHICE. No V2-format posts were received. Plate posts from this firmware therefore follow the IPC Event Format (v1.x), including vehicleListType for listed plates.

No V2.1-format post body has been captured yet, so this page does not document one.
