Detector is a software object (part of the software environment) that represents an algorithm or a set of algorithms that allows you to analyze video and audio streams according to a predefined scenario and signal the analysis results by creating events within the software environment.

Sub-detector is a detector that processes the data received from the parent detector.

By default, no action is performed in the system when an event from a detector or sub-detector is received. To perform an action, you must create an automatic rule (see Automatic rules) or macro (see Programming).

Also, the default detector list displays camera inputs (see Configuring the Input object) that you can use in an automatic rule.
