Security Video on the Edge

June 1st, 2012 | by admin admin | in Security Advice |    0   

Armed and Dangerous Male Wanted for Attempted Murder. The Burnaby RCMP issued an urgent public warning on Wednesday morning, May 30. Within three hours, the suspect and his green Aerostar van had been located. Angus David Mitchell, 26, died following a shoot-out.

Imagine if Mitchell had fled into Metrotown or Stanley Park, your office tower or parkade. Would he get lost in a crowd? How could you track that green van in traffic? Traditional surveillance videos don’t seem up to the job.

Just as high-definition video technology has changed how you watch TV, video security technology offers so much more today than grainy images on a monitor. High-definition video surveillance cameras capture six times the number of pixels of traditional cameras. That means you need fewer cameras to cover the same area.

But even if you could capture Mitchell’s image clearly on a security camera, how would you follow him in a mall full of shoppers?

Video analytics technology processes images to recognize patterns of movement. A security camera could lock in on, for example, the way Mitchell ran. Computer algorithms could separate foreground from background to track him.

Edge (on-camera) video analytics, meanwhile, takes high-definition video analytics a step further. By processing images in the security camera instead of transmitting them to a separate server, edge analytics automatically monitors a greater range and field of view. This on-camera solution bypasses bandwidth limitations and foreground/background computations.

Instead, edge analytics relies on advanced pattern recognition, using hundreds of thousands of models of humans, vehicles and boats, instead of modelling pixels. The sophisticated processor algorithms also adapt to changing input (feedback-based learning and adaptive analytics) to achieve higher accuracy with less need for processing power or manual adjustments. Manufacturers claim these HD video surveillance cameras with edge analytics provide 2X the range and 3X the field of view of traditional standard-definition security cameras.

It would be technologically possible to lock in on Mitchell as he entered a building, and automatically track him through a crowd of commuters. Check out these Youtube clips of surveillance video. The HD edge video analytics actively searches for recognizable patterns of movement and monitors those moving objects.

That’s security video on the edge.
