Firearms And Knives Detection

New Technology aims to improve Firearm Detection and Save Lives with VisionAI.

Firearms And Knives Detection

Detection of firearms and knives event

Overview

Firearms detection refers to the use of technology and methods to identify the presence of firearms in a particular location or setting. The goal of firearms detection is to prevent violence and ensure public safety by detecting and responding to the presence of firearms including knives, guns and other weapons.

There are various methods and technologies used for firearms detection, including metal detectors, X-ray machines, and millimeter-wave scanners. All these solutions are invasive.

With the advent in technology, our VisionAI solution for fire-arms detection is non-invasive in nature and it works by analyzing video footage to detect the presence of firearms or other weapons.

Vision AI based monitoring

Vision AI based monitors can be used to detect Firearms and knives events by providing real-time video feeds of the factory area. The cameras scan every frame to ensure there is no sign of firearms and knives.

Events

VisionAI model's generated events would be:

  • Person brandishing firearm
  • Person brandishing knives

Model Details

Dataset

The dataset for this scenario is based on real-world firearms and knives events. The dataset consists of images and videos collected from various sources including UC Berkeley Anomaly Detection Dataset, UCF Crime Dataset etc.

Model

The model is based off of the YOLOv5 algorithm. The model is trained on a custom dataset of images and videos. The model is trained based on the above dataset compiled by our team.

Model card

Dataset size Version Camera support Accuracy Recall F1 score
4230 v7 Ceiling 98.2 95.2 95

The model is adaptable enough to run on any edge computing device.

Scenario details

The business logic for this scenario is as follows:

  • We use existing camera feeds from the premises to detect firearms and knives events.
  • VisionAI system is able to run on edge devices. It uses camera feeds for processing.
  • We detect people in the camera feed and we monitor whether the person is carrying any firearms and knives.
  • If the person is detected with this event, an alert is raised.

To test this model & scenario, you can use the following steps:

  • Install the visionai package from PyPI

    $ pip install visionai

  • Test the scenario from your local web-cam

    $ visionai scenario test firearms-knives-detection

Downloading models for scenario: firearms-knives-detection



Starting scenario: firearms-knives-detection..

  • You should be able to see the events generated on your console window with the detections of firearms and knives within the camera field of view.

VisionAI app is available at a Azure Market place, one can download and use it by following steps mentioned here

Features

The VisionAI solution is the most efficient way of implementing this scenario, as evidenced by the following features:

  • Unmatched accuracy

    Trained and Tested to give the best results. Our systems are trained to detect firearms and knives at the earliest detection with an accuracy of 99%

  • Lightning Fast and Response Time

    Our Ultra-fast Processing provides real-time inference results and feedback (~30 frames per second processing).

  • Minimizing false-positives/negatives

    Our systems create a fail-proof system by ensuring there are no false-positives or false-negatives.

  • Scalability and Deployment

    Our pre-trained/custom models can be deployed instantly and are camera independent which means they can be pre-installed with existing cameras on site. We also offer cameras, IoT sensors and edge devices with strategic placement that helps scale a large workplace area with minimum installations.

  • Custom Integrations

    Our detection system can be integrated with other safety systems, such as building management systems or alarm systems, allowing for a coordinated response to emergencies.

Training with custom data

The scenario is provided as part of our GPL-v3 package for VisionAI. If you wish to train this with custom datasets, please contact us and we can provide you with the training code. You can do custom training with your own datasets for free, as long as it complies with GPLv3 license (you give back the code to the community). If you are interested in a custom license, please (contact us)[contact.md].
