   Device for Analysis

   Time Period

   Set a time period for counting the appearance times of a detected person.

   Appeared Times

   Set threshold times for regarding a detected person as a frequently appeared person.

   If the times that a person is detected by the specified camera(s) reaches or exceeds the threshold within the time period you set, he/she will be regarded as a frequently appeared person.

   Set a time interval for filtering out invalid counting.

   If a person is detected for multiple times within the time interval, the system will regard he/she only appeared for one time.

   Similarity

   Drag the slider to adjust the similarity threshold based on your facial recognition requirements. The higher the threshold, the preciser the recognition will be. The lower the threshold, the higher recognition rate will be.

   Once the similarity between a detected face and a face picture in the selected face comparison group(s) reaches the threshold, the detected face will be recognized and a face comparison record will be generated.
