AI analytics are increasingly applied to surveillance video streams to automatically flag unusual activity in real time, but their accuracy falls short. Oyla’s approach is fundamentally different: obtain better data as input to the AI in the first place. To this end, Oyla has developed a unique AI-based video surveillance system which augments the video with a an inexpensive proprietary 3D sensor. The 3D sensor is integrated with the video sensor at a hardware level, and collects 3D data across the video field of view at up to 50 meter range. The 3D data stream is independent of the video stream, and so statistically improves the accuracy of the video AI. This 3D sensor provides its own infra-red illumination and so can operate in complete darkness. It can also be used to define very accurate intrusion detection perimeters.
