  Inspired by [this discussion](https://ai.stackexchange.com/q/1481/8) about recognizing human actions, I have found the [Fall-Detection](https://github.com/harishrithish7/Fall-Detection) project which detects humans falling on the ground from a CCTV camera feed, and which can consider alerting the hospital authorities.
  
  My question is, are there any existing real-life implementations or research projects **which specifically use live video feed from the surveillance cameras in order to detect crime** using convnets (or similar approaches)? If so, how do they work, briefly? Do they automatically inform the police about the crime with the details what happened and where?
  
  For example car accidents, physical assaults, robberies, violent disturbances, weapon attacks, etc.
