Version: 3.0.6

Custom Integration

Ultinous AI Suite is not only a standalone solution but can be used in an integrated system as well. All important information that belongs to an incident (eg. location, timestamp, detection coordinates, etc.) can be sent instantly to a third party software.

HTTP message

An external API endpoint can be set for each alarm. Whenever an alarm is triggered, a POST message will be sent to the API with metadata that belongs to the incident.

To enable snapshot sending, tick its checkbox under the respective Solution's HTTP webhook settings.

Message schema

The content type of messages is application/json. The content is described in proto in this document.

End of event

It is possible to include an End of Event timestamp, which triggers if 5 seconds have passed without incidents after the initial event that triggered the HTTP message. End of Event occurs once the incident is over.

NOTE 1: detections is an empty array, and end_of_event is true.

NOTE 2: the id of this event is unique and it does not refer to any former event. This means that all events with this display_name and type are to be considered as having ended.
