Hands up detector for video surveillance systems

Do you know what is the most common sign to indicate that we’re in dangerous situation in face of a robbery?

– Hands up!

If you got it right, it is because unfortunately you have witnessed or experienced situations like this.

In Ebenezer Technologies we know that is hard to deal with these situations. That is why we have been offering to our clients a concept equipped with intelligent video analytics ideal for video surveillance systems, wich we have called: Hands up detector or Invisible panic button.

That’s right! Like these devices, it would work silently without for some kind of switch or button to send alerts in an emergency.

For this reason, in the following article we will tell you how this technology with Artificial Intelligence works, and what you need to deploy this detector in your security camera system.

Action recognition with AI

Before delving into this solution, it is necessary to know what is behind this technology in charge of detecting people’s actions. This Deep Learning application uses a neural network to analyze images or videos and detect patterns that indicate the presence of a specific action, such as walking, running, jumping, etc.

All this is done by monitoring the position or actions of people through a skeleton tracker, which consists of a system that uses computer vision technology to track the position and orientation of the bones of the human body in real time. This is achieved through the use of cameras and motion tracking algorithms.

The data collected by the tracker is used in applications such as game control, digital animation, physical therapy, human movement research, or video surveillance.

Alice Security for surveillance systems

Now that we know in a general way how this technology works, we will transfer this whole concept to the world of security and surveillance. Here we start from the need to provide solutions equipped with Artificial Intelligence that allow us to improve or optimize security work.

It is evident that every day we see criminal acts of all kinds that violate the security of both people and the site in question. Where dangerous situations occur almost instantaneously, preventing an effective reaction by the personnel in charge of monitoring the site.

It is at these critical stages that Alice Security comes in to mitigate these events by using AI algorithms through the focus of security cameras. Giving you the possibility to see further and have a situational analysis of the environment; allowing you to classify people, objects and actions in real time.

How the hands up detector works

In the event that you find yourself in the middle of an assault, robbery or any type of threat, the action of raising your hands is detected by the security camera and instantly generates an alert or notice of the event to the monitoring center.

One of the advantages that Alice offers is its versatility when it comes to managing the alerts that are received. This means that the control point operator can previously configure the alerts so that he can confirm them once they are generated. or do it automatically.

Once this action is confirmed, Alice allows you to perform the following security actions:

• Send notification with image and video of the facts through the Telegram mobile application.
• Confirm the alerts generated on the web platform or via Telegram.
• Activate in a matter of seconds any type of alarm, strobe light, loudspeaker system, anti-theft smoke or any device that has been previously configured with Alice.
• You can send these alerts to the nearest law enforcement authorities or police stations for immediate action.

This gives us a better reaction to this type of situation where what is sought is to act in the best possible way, helping to reduce and prevent the risk that these generate.

Main benefits of Hands up detector

• Better risk reaction and control: Traditional surveillance systems simply record and are not capable of instant deterrence of critical events.
• Reduction of personal risk: Although robbery or theft situations are situations of great care, an action detector system can provide peace of mind that all evidence is recorded and alerted to the pertinent persons or authorities.

Smart Alerts

As we have been showing you, Alice’s smart alerts are generated in real time and can be confirmed automatically or manually in the event of a false alarm or mistaken raising of hands.

Also, when an alert is generated, Alice show a little windows notifacation in the lower right corner with a image and type of event, which can be seen in greater detail in the alert management panel with the following valuable information:

• Date and time of alert.
• Photo and short video of event.
• Animated GIF with the generated action.
• Geographical location of the event.

Where Hands Up Detection Can Be Used

This solution requires choosing those strategic points where the hands-up detector will be installed through the creation of safe zones. For this, the ideal is the selection of points where there is greater vulnerability, such as: cash registers in shopping centers, bank tellers, building receptions, prisons, among others.

What do I need to deploy hands up recognition

These solutions require the connection with IP or analog cameras through the ONVIF RTSP protocol in order to perform video analytics on the server with Alice Security.

To achieve optimal functionality, it is necessary to carry out a security analysis where a study of the site is carried out and the camera is calibrated according to the lighting conditions of the environment, camera position and others.

If you want to test this functionality in your current security camera system, contact us and let us provide you with the solution that best suits your needs.
