More Hitachi Video Analytics - Identifying an Intruder
There were a number of test videos that impressed me when I did the sample video clips for Hitachi Video Analytics. In my previous Digital Video Analytics -Test Results post, I expressed my amazement of how Hitachi Video Analytics can even filter out a blizzard. It can read and comprehend the difference between wind blowing snow and the snow on the ground from over five million pixels per second.
This is another one of those handful of tests that impressed me. In the clip (snapshot above), you can see that Hitachi Video Analytics Intrusion Detector may not recognize the animals as a cat, a racoon or a rabbit, it does understand that they are irrelevant as calibrated. What is impressive, is the person walking the dogs. Notice how the analytics also ignore the dogs, or the big blob of pixels that is the dogs and man, but just identifies the person walking the dogs and once validated as a human being intruding within the protected area, sends an alert. Intrusion Detector can be calibrated to recognize people.

When presenting this demonstration video, someone asked me if this Hitachi Video Analytics Intrusion Detector could recognize a person, if they were crawling.
Well, my curiosity got the best of me. I really wanted to know, and so, using the same camera and same calibrated Intrusion Detector, I decided to find out. After a few failed attempts at trying to convince someone to crawl around my front yard, I realized I would have to do it.
I really just wanted to know.
And so, because I’d rather not have a video on the Internet of me crawling around my front lawn, I decided to add Privacy Protector to the stream as well. It really doesn't matter who it is, only that its smart enough to identify a human crawling around like an animal, but not an animal.
I created the following sample, eliminating the various overlays of analytics meta data that you see in the previous test sample. I didn't re-calibrate the configuration and intelligence as it's difficult to do while crawling around the front lawn, but it appears I didn't have to; it recognized me as a human intruder and sent the alert.
