Introduction
The Face recognition model is designed to provide access through the turnstile/door by facial recognition.
Camera location
Camera location
The camera must be located in the same room as the relay it will control, otherwise the relay will not work on recognition/detection.
Analytics settings
In the camera edit, switch to the Video analytics section.
Click Edit on the Face recognition model.
Select the desired camera from the list.
Basic settings
- Face size in frame — ratio of frame height to face height. It can be set by manually entering a value between 0 and 1 in the field or by interactively selecting the size on the image.
- Sensitive — level at which recognition occurs. The number is from 0.1 to 1. The lower the number, the higher the sensitivity.
- Passage intent threshold — value at which passage will be completed. A number between 0 and 1.
- Face recognition threshold — a value indicating the extent of matching between a face and an employee's photo required for identification. A number from 0 to 1.
Setting the Sensitive parameter
When the sensitivity of the face detection model is high, it may be triggered by noise and distortions not related to the face.
The sensitivity is adjusted experimentally to ensure guaranteed face detection in the frame while minimizing false alarms due to noise.
An example of an ultra-high sensitivity of 0.01.
Detection zone
Detection zones — the areas in which recognition occurs.
Click the Add zone button, place a zone on the image through white dot interactions.
Configuring the detection area of the detection zone
By default, once the detection zone is created, it is formed as a rectangle placed in the center.
- Left mouse click with holding on the blue area of the zone — move the whole zone;
- Left mouse click with holding on the white dot — move the edge of the zone;
- Left mouse click on the edge of the selected zone — create an additional zone point.
Actions
Move the switch to the active position, click the Add action button.
Then select the type of action — Relay/Record to archive, the desired relay from the list, and the relay action — Open/Closed/Pass.
