Visitors faces can be used as an identifier to get access to a place. In this you can complete the following actions:
enable/disable the face recognition feature;
choose a suitable similarity level (the lower the similarity level, the greater the error can be in scanning a face and granting access):
Low: the minimal similarity is necessary for access (changes in appearance (glasses, beard, presence of a hat) will not be taken into account);
Normal: some changes in appearance are taken into account, but not detailed (recommended for homes and offices);
High: the maximum similarity is necessary for access (recommended for high-security places).
set the appropriate mode (Live Detect):
Software: the software recognition algorithm is used, and there is a possibility of giving access by photos;
Anti-spoofing: more detailed software recognition algorithm is used to prevent access by photos;
3D (is available for panels with a built-in 3D sensor): detailed face recognition using IR sensors and building a face heat map to prevent spoofing.
