How are AI Detection Distances Determined?
OpenEye AI detection distances vary depending on camera mounting position, lighting conditions and camera focal length, but not camera resolution. Video is scaled to ~640x360 (depending on original low stream resolution) before being processed by the AI. When calculating pixels per foot (PPF), use 640x360 for 16:9 aspect ratio cameras and 640x480 for 4:3 aspect ratio cameras.
AI Distance, Recognition, and Identification
To help predict detection distance, the AI DRI (Distance, Recognition, Identification) distances for an OpenEye camera model have been provided below. Distance is the distance at which people can be detected. Recognition is the distance at which people can be categorized by the color of their clothing. Identification is the distance at which people can be re-identified in other cameras by their facial details*.
