Security surveillance cameras have come a long way from grainy resolution and minimalist functions. Those old cameras used “motion detection” to create an alert for suspected security breaches. Unfortunately, most of the suspected breaches were birds, roaming animals, and people walking by without ill intent. Modern security surveillance applies smart video analytics to eradicate nuisance alarms and draw attention to only credible threats.
Where is the analysis done?
Today, most camera systems provide advanced field-of-view analytics. These systems are classified into two categories: onboard analytics and server-based analytics.
Surveillance cameras with onboard analytics run the analytics before the video data is sent across the network to viewers and data storage appliances. Server-based analytics require powerful computers to analyze video streams that come in from surveillance cameras.
What types of behavior can be detected?
In most cases, the presence, activity, and identity of people are the main concern. Who is in front of the camera and what are they doing? With high definition cameras, identification can be accomplished post-incident or live if the camera is being monitored by a security officer. But, with most facilities having so many cameras, it’s extremely helpful for the camera system to generate an alert for something abnormal. Early notification can prevent or mitigate crimes.
Common behavior detection criteria:
• Line crossing
• Multiple line crossing
• Crossing a line in a specific direction
• Following a specific path
• Loitering
• Parking in no parking zones
• Entering a restricted area
Using the common criteria above can assure officers that their attention is focused on detecting questionable behavior.
Beyond unauthorized behavior
Video analytics are commonly used for additional capabilities such as people counting. Knowing the number of people that enter a building and where they go once inside in the form of a heatmap can provide operations teams with critical information about employee traffic patterns in warehouses or industrial buildings or in venues such as stadiums or arenas.
This is accomplished by placing dual-purpose cameras in “birds-eye-view” positions. Panoramic cameras can not only provide a security function by recording visual images, but also look down on the scene from above and recognize, through advanced analytics, the head and shoulders of a human while ignoring carts, industrial machines, and other objects in the scene.
