Automated camera activation

A system, comprising:

• one or more processors;
• and
• memory including a plurality of computer-executable components that are executable by the one or more processors to perform a plurality of acts, the plurality of acts comprising:
• receiving from a sensor that is separate from the system, a first sample of sensor data and a second sample of sensor data;
• providing the first sample of sensor data and the second sample of sensor data to a model that is trained using machine learning, that is configured to receive given sensor data from a given sensor, and that is configured to output a given confidence score that indicates a likelihood that a given firearm has been removed from a given holster;
• receiving, from the model, a confidence score that indicates a likelihood that a firearm has been removed from a holster;
• comparing the confidence score that indicates the likelihood that the firearm has been removed from the holster to a confidence score threshold;
• based on comparing the confidence score that indicates the likelihood that the firearm has been removed from the holster to the confidence score threshold, determining that a firearm has been removed from a holster;
• based on determining that the firearm has been removed from the holster, generating, by an event generator of the system, a software-recognized event that indicates the firearm has been removed from the holster;
• providing, by the event generator of the system and to an event publish/subscribe service of the system, the software-recognized event that indicates the firearm has been removed from the holster;
• determining, by the event publish/subscribe service of the system, that an event subscriber has subscribed to given software recognized events that indicate a given firearm has been removed from a given holster;
• and
• in response to (i) receiving the software-recognized event that indicates the firearm has been removed from the holster and (ii) determining, by the event publish/subscribe service of the system, that the event subscriber has subscribed to the given software-recognized events that indicate the given firearm has been removed from the given holster, providing, by the event publish/subscribe service of the system and to the event subscriber using a message queueing telemetry transport protocol, the software-recognized event that indicates the firearm has been removed from the holster, wherein the event subscriber is configured to transmit, to a video sensor, a request to generate video data.

One or more non-transitory computer-readable media storing computer-executable instructions that upon execution cause one or more computers to perform acts comprising:

• receiving, from a sensor that is separate from the computing-devise one or more computers, sensor data;
• providing the first sample of sensor data and the second sample of sensor data to a model that is trained using machine learning, that is configured to receive given sensor data from a given sensor, and that is configured to output a given confidence score that indicates a likelihood that a given firearm has been removed from a given holster;
• receiving, from the model, a confidence score that indicates a likelihood that a firearm has been removed from a holster;
• comparing the confidence score that indicates the likelihood that the firearm has been removed from the holster to a confidence score threshold
• based on comparing the confidence score that indicates the likelihood that the firearm has been removed from the holster to the confidence score threshold, determining, that a firearm has been removed from a holster;
• based on determining that the firearm has been removed from the holster, generating, by an event generator of the one or more computers, a software-recognized event that indicates the firearm has been removed from the holster;
• providing, by the event generator of the one or more computers and to an event publish/subscribe service of the one or more computers, the software-recognized event that indicates the firearm has been removed from the holster;
• determining, by the event publish/subscribe service of the one or more computers, that an event subscriber has subscribed to given software recognized events that indicate a given firearm has been removed from a given holster;
• and
• in response to (i) receiving the software-recognized event that indicates the firearm has been removed from the holster and (ii) determining, by the event publish/subscribe service of the one or more computers, that the event subscriber has subscribed to the given software-recognized events that indicate the given firearm has been removed from the given holster, providing, by the event publish/subscribe service of the one or more computers and to the event subscriber using a message queueing telemetry transport protocol, the software-recognized event that indicates the firearm has been removed from the holster, wherein the event subscriber is configured to transmit, to a video sensor, a request to generate video data.
