VIDEO ANALYTICS – WHAT DOES THAT MEAN AND WHAT THEY CAN DO FOR YOU

What are video analytics?

To increase overall security, and to protect people and assets from incidents, theft, and terrorist attacks, the number of video security cameras being utilized is increasing at a high rate.  Consequently, the number of security personnel has not increased at the same rate, resulting in an average range of 25 to 50 cameras (or more) being monitored by each security person. The need to view multiple monitors and multiple cameras simultaneously causes viewing fatigue which can lead to a higher probability of missing critical events.  

Video analytics is a technology which can alert personnel of certain activities by analyzing video information.  Using this technology can help your personnel quickly detect certain conditions, and to minimize potential damage through a prompt response.  Analytics can also be used during recording and search operations, allowing personnel to search recorded video for certain event types. This enables you to quickly locate an incident, thereby saving valuable time.

What type of analytics are available?

There are many different types of video analytics available today, and each solution will work differently depending upon the manufacturer.  However, they all work in the same basic way – you set up certain parameters for the activity to look for, set up an alert notification system, and then when the activity that meets your search criteria is detected, the software alerts you.  Analytics vary from manufacturer to manufacture, and even by model. Here are some examples of what video analytics can be used for, along with a brief description of each:

  • Virtual Line Crossing Detection – An object crossing a designated virtual line can be detected.  The direction of an object crossing the virtual line can also be specified.
  • Motion Detection – Movement can be detected within the entire scene or in a designated virtual area that can be defined.
  • Object Left Behind Detection – An object appearing in a designated virtual area and remaining there for longer than a preset time can be detected and reported.
  • Object Removed Detection – An object disappearing from a designated virtual area and remaining gone for longer than a preset time can be detected and reported.
  • Tamper Detection – Detects sudden changes that may affect the normal monitoring of a camera.  Such conditions may include:
    • Movement of the camera due to an impact
    • Loss of video due to the camera being covered, spray painted, or intentionally blocked by other means
    • Significant loss of camera focus
  • Face Detection – Identifies human faces by identifying key features of a human face
  • Business Intelligence – Analytics such as people counting and heat mapping can be used to analyze customer behavior and improve your customer experience.

How can video analytics help you?

Video analytics offers many benefits, such as more efficient use of staff and faster access and retrieval of stored video.  The typical idea of video surveillance system is a security guard sitting in a room watching the security monitors of live camera feeds, hoping to catch suspicious activity.  Different security guards may have differing levels of focus or different ideas of suspicious activity. Research in the United States has shown that human observers of video systems start showing signs of fatigue in as little as 12 minutes, overlooking up to 45% of activity in the camera scenes.  After 22 minutes, that increases up to 95% of overlooked activity.  

Video analytics leverages your software to monitor video feeds 24/7/365, alerting your staff to pre-defined activity, so they will only need to watch the cameras when something happens.  This will help you best utilize your surveillance system, saving you time and effort and creating increased business value by delivering more specific and targeted information.

Conclusion

A video surveillance system is only as useful as the incidents that you can actually capture and watch.  By analyzing surveillance video in real-time, video analytics will make your system more efficient and reduce the fatigue on your security staff, making your system more cost-effective and easier to manage.  Leveraging analytics technology can enable a single individual to monitor many more cameras and reduce the amount of missed critical events, therefore enabling a prompt response making it possible to prevent a crime rather than just respond to it after the incident.
