Counting Mode
: You can do precise face counting with two default function databases
(all people database and exclude people database). The faces detected by the camera
will be uploaded to the all people database automatically; the face in the exclude
people database will not be counted. Add faces that you do not want to count (such as
repeating faces and loitering faces) into the exclude people database so that the
system will not count the faces after detecting them.
Step 4 Click next to Enable to enable the face detection function.
Step 5 (Optional) Click other icons at the right side of the image to draw detection area, exclusion
area, and filter targets in the image.
●
Click to draw rule line in the image.
When targets enter or leave the detection area along the direction line, their face
images will be uploaded to the all people database, and then the system will determine
whether to count it after comparing with that in the exclude database.
This icon is only available in counting mode.
