attacks
IP68 dust-proof and waterproof standard and IK04 protection standard
2MP starlight CMOS sensor camera with WDR function, which enables the terminal to recognize
faces under extreme lighting conditions (0 to 100,000 lux)
Mask detection and facial verification are both available while using masks.
Supports static QR code and Dynamic QR code with ZKBioSecurity Mobile APP optional
There are two types of card modules available: 12.5 kHz EM card and 13.56MHz IC card (optional))

Correct face registration and authentication method
Recommendation for registering a face
Maintain a gap of 40cm to 80cm between the device and the face while registering it.
Be careful not to change your facial expression. (Smiling face, drawn face, wink, etc.)
If you do not follow the instructions on the screen, the face registration may take longer or may
fail.
Be careful not to cover the eyes or eyebrows.
Do not wear hats, masks, sunglasses, or eyeglasses.
Ensure that the screen does not have two faces. You can only register one person at a time.
It is recommended for a user wearing glasses to register both faces with and without glasses.
Recommendation for authenticating a face
Ensure that the face appears inside the guideline displayed on the screen of the device.

even more if it has already been registered. Authenticate the face with the previously worn
glasses if they face with glasses has been registered.
If a part of the face is covered with a hat, a mask, an eye patch, or sunglasses, authentication may
fail. Do not cover the face, allow the device to recognize both the eyebrows and the face.
