JSON format

Field	Type	Description
stream_id	String	Camera ID
event_type	Uint64	Event type of the output message. For an intrusion detection event, the value is fixed to 196609, which is 0x 0000 0000 0003 0001 in hexadecimal format. For a loitering detection event, the value is fixed to 196610, which is 0x 0000 0000 0003 0002 in hexadecimal format.
task_id	String	Task ID
message_id	String	Alarm ID in the form of a UUID
timestamp	Uint64	Time when the alarm is triggered
image_base64	String	Base64 encoding results of the video image when the alarm is triggered
data	Object	Service output content

data parameter description

Field

Type

Description

event_set

List<Object>

List of events generated

Field	Type	Description
event_set	List<Object>	List of events generated

event_set parameters

Field	Type	Description
bounding_box	Object	Rectangle for the alarm object
detection_id	String	UUID of the alarm object
category	Int	Alarm target type. The value can be: 0: person 1: vehicle 2: other
start_position	String	Start position of the intrusion. This parameter is not generated for loitering detection. For an intrusion against a line, the value is the name of the side from where the object enters. For an intrusion into a region, the value is in or out. in: The intrusion starts inside the region. out: The intrusion starts outside the region.
end_position	String	End position of the intrusion. This parameter is not generated for loitering detection. For an intrusion across a line, the value is the name of the side where the object arrives. For an intrusion into a region, the value is in or out. in: The intrusion ends inside the region. out: The intrusion ends outside the region.

bounding_box parameters

Field	Type	Description
x	Int	Horizontal coordinate of the upper-left corner of a bounding box
y	Int	Vertical coordinate of the upper-left corner of a bounding box
w	Int	Width of a bounding box
h	Int	Height of a bounding box
