# What does the facial recognition matching level mean?

**Facial Recognition Matching Level** defines how strict the face comparison is when users authenticate with face recognition. Higher levels require a more accurate match and allow less face occlusion.

Available levels:

- **Low:** Users can pass recognition if no more than **15%** of the face is covered (mouth not included).
- **Normal:** Users can pass recognition if no more than **10%** of the face is covered (mouth not included).
- **High:** Users can pass recognition if no more than **5%** of the face is covered (mouth not included).
- **Highest:** Users can pass recognition only when the face is almost completely visible.

> [!NOTE]

> Higher matching levels improve security but may reduce recognition speed or tolerance in real deployment.

**Face Living Recognition Matching Level** defines the anti-spoofing strength of the device. It determines whether photos or screen images can be used to bypass face recognition.

Available levels:

- **Close:** Paper photos and electronic photos can pass recognition.
- **Low:** Black-and-white paper photos (single camera) and electronic photos (dual cameras) cannot pass recognition.
- **Normal:** Black-and-white paper photos and electronic photos cannot pass recognition.
- **High:** All paper and electronic photos (color or black-and-white) cannot pass recognition.
- **Highest:** Only real human faces can pass recognition.

> Use higher liveness levels in high-security environments to prevent photo or screen spoofing attacks.
