The left video shows a market-leading thermal camera which does not detect a UPS truck at close proximity. There is also a person off in the distance which is not detected. The UPS truck close-in is not detected because this system does not employ GPS-based sized filters, and has difficulty determining an object's actual size. In the right video, the SightSensor not only shows more image detail, it is also detects multiple targets of various sizes. Because of GPS filters and image processing, accuracy can be maintained in these imaging environments of widely varying target sizes. Note the person off in the distance that is detected.
