Update camera AI thresholds

Update AI confidence thresholds for a camera

POST/api/camera/updateCameraAIThresholds

Authorizations

x-auth-apikeystringheaderrequired

Your Rhombus API key. Must be accompanied by the x-auth-scheme header set to api-token (or partner-api-token for partner endpoints).

Authorizationstringheader

Instead of an API key, an OAuth access token: Bearer <token>, with the write scope.

OAuth explains tokens and scopes.

Headers

x-auth-schemeenum<string>headerdefault: api-token

Authentication scheme identifier. Use api-token or partner-api-token with the x-auth-apikey header, api or partner-api with x-auth-apikey plus a client certificate, api-oauth-token or partner-api-oauth-token with x-auth-access-token, and federated-token with x-auth-ft. A request with Authorization: Bearer <token> and no x-auth-scheme is treated as OAuth, and federated-token may also be sent as the x-auth-scheme and x-auth-ft query parameters.

Available options: api-token, api, api-oauth-token, federated-token, partner-api-token, partner-api, partner-api-oauth-token

x-auth-orgstring<RUUID>header

Client organization UUID (22-character RUUID), for partner credentials only. With it the call runs in that client organization with the partner support authority's role. Without it a partner credential runs as the partner organization, which outside the partner endpoints is deprecated (responses carry Deprecation and Sunset: Tue, 05 Jan 2027 00:00:00 GMT). A malformed value returns 400 INVALID_AUTH_ORG; a client organization the partner cannot access returns 403 PARTNER_CLIENT_ACCESS_DENIED.

Length: 22 to 22

Body

application/json · object

Request to update AI thresholds for a camera.

cameraUuidstring<DeviceFacetUuid> | nullbody

RUUID with optional appended facet information

Example: "AAAAAAAAAAAAAAAAAAAAAA.v0"

consecutiveHumanFilterinteger<int32> | nullbody

Require this many consecutive frames of seeing a human to include that human detection in results. Set to 1 to always include detections, or higher to avoid false positives due to transient motion like bugs/spiders/rain. Default is 2 consecutive frames.

Example: 3

consecutiveVehicleFilterinteger<int32> | nullbody

Require this many consecutive frames of seeing a vehicle to include that vehicle detection in results. Set to 1 to always include detections, or higher to avoid false positives due to transient motion like bugs/spiders/rain. Default is 2 consecutive frames.

Example: 3

faceConfidenceThresholdnumber<float> | nullbody

Confidence threshold for face detection. Set to 0 or null to use the default. Maximum range of 1. Default = 0.7

Example: 0.8

faceMatchConfidenceThresholdnumber<float> | nullbody

Confidence threshold for face matching (determining if two faces are the same person). Set to 0 or null to use the default. Maximum range of 1. Default = 0.7. We no longer support device specific face matching threshold. This property is deprecated and will be removed.

Example: 0.8

humanConfidenceThresholdnumber<float> | nullbody

Confidence threshold for human detection. Set to 0 or null to use the default. Maximum range of 1. Default = 0.6

Example: 0.7

lprConfidenceThresholdnumber<float> | nullbody

Confidence threshold for license plate detection and character recognition. Set to 0 or null to use the default. Maximum range of 1. Default = 0.8

Example: 0.9

maxEventDurationMsinteger<int32> | nullbody

Set the max event duration for an alert in milliseconds. Default is 30000, lowering down to 4000 will result in faster alert delivery but shorter alert clips.

Example: 15000

vehicleConfidenceThresholdnumber<float> | nullbody

Confidence threshold for vehicle detection. Set to 0 or null to use the default. Maximum range of 1. Default = 0.6

Example: 0.7
