Face Detection - Speco O2BFR User Manual

※ Configuration requirements of camera and surrounding area
1. Cameras must be installed in the area with stable and adequate light sources.
2. The background color (like floor color) should be light color.
3. The lens of the camera should be adjusted straight down to ensure that the whole head of the people can be captured.
4. The installation height of the camera depends on the actual focal length of the lens. The entrance/exit in the image should make
up over a half of the width of the entire image and the head of a single person should account for about 1/5 of the height of the
entire image. Remember leaving a certain space on both sides to let the entrance/exit lie in the center of the entire image.
5. Various changeable lights will disturb the people counting and the dark scenes will reduce the accuracy of counting.
6. If someone is moving at a high speed (passing the detected area within 2 seconds), it may result in detection failure. However, if
someone is moving at a low speed, staying more than 15 seconds in the detected area, the camera will give up tracing.
7. If the cloth colors of people are similar with the color of the background, it may cause detection failure.
8. More headwears which probably conceal the head features will lead to detection failure.
