SignalGateProcessor Class

A signal gate determines when to block (gate) incoming media, and when to allow it through. It gathers input events over the activationEvaluationWindow, and determines whether to open or close the gate. See https://aka.ms/ava-signalgate for more information.

All required parameters must be populated in order to send to Azure.

SignalGateProcessor

Constructor

SignalGateProcessor(*, name: str, inputs: List[azure.media.videoanalyzeredge._generated.models._models_py3.NodeInput], activation_evaluation_window: Optional[str] = None, activation_signal_offset: Optional[str] = None, minimum_activation_time: Optional[str] = None, maximum_activation_time: Optional[str] = None, **kwargs)

Variables

type

str

Required. Type discriminator for the derived types.Constant filled by server.

name

str

Required. Node name. Must be unique within the topology.

inputs

list[<xref:azure.media.videoanalyzer.edge.models.NodeInput>]

Required. An array of upstream node references within the topology to be used as inputs for this node.

activation_evaluation_window

str

The period of time over which the gate gathers input events before evaluating them.

activation_signal_offset

str

Signal offset once the gate is activated (can be negative). It determines the how much farther behind of after the signal will be let through based on the activation time. A negative offset indicates that data prior the activation time must be included on the signal that is let through, once the gate is activated. When used upstream of a file or video sink, this allows for scenarios such as recording buffered media prior an event, such as: record video 5 seconds prior motions is detected.

minimum_activation_time

str

The minimum period for which the gate remains open in the absence of subsequent triggers (events). When used upstream of a file or video sink, it determines the minimum length of the recorded video clip.

maximum_activation_time

str

The maximum period for which the gate remains open in the presence of subsequent triggers (events). When used upstream of a file or video sink, it determines the maximum length of the recorded video clip.
