# Face Login/Enroll error list and mitigation ways

> These steps will help ensure a successful face enrollment process, resulting in accurate and reliable recognition.

### Face Enrollment Guidelines

### Positioning

* **Face the Camera**: Look directly into the camera and ensure your face is centered in the frame.
* **Frame Your Face**: Position yourself so that there are 1-2 inch margins around your face, avoiding extreme angles and poses.
* Only one person should be present during face registration.

### Expressions

* **Neutral Expression**: Keep a neutral expression, avoiding exaggerated facial movements.
* **Remove Glasses**: If you are wearing dark glasses or tinted lenses, remove them to ensure both eyes are clearly visible.

### Lighting

* **Avoid Bright Backlighting**: To prevent shadows and glare, ensure the lighting is even. Avoid bright lights directly behind you.
* **Optimal Lighting Conditions**: Use soft, even lighting to enhance the clarity of your image.

### Focus & Movement

* **Image Clarity**: Ensure the captured image is sharp and not blurry, as image focus is crucial for accurate recognition.
* **Adjust Distance**: If the camera is having difficulty focusing, you might be too close or too far from the device.

These steps will help ensure a successful face enrollment process, resulting in accurate and reliable recognition.

![Face Login/Enroll error list and... - screenshot 15](https://mintcdn.com/oloid-999c42b2/9D2pDBnahjm71jl4/images/intercom/9668957/image-a00f1854.png?fit=max\&auto=format\&n=9D2pDBnahjm71jl4\&q=85\&s=7dcb104f90ace4dca945bd4e3649e1e4)

* **Description**: The captured face image does not match the reference image stored in the system, possibly due to changes in appearance or image quality issues.
* **Mitigation Strategies**:
  * **Match Reference Conditions**: Try to replicate the conditions under which the reference image was taken. This includes similar lighting, facial expressions, and camera angles.
  * **Update Reference Image**: If your appearance has significantly changed (e.g., wearing glasses, new facial hair), consider updating your reference image in the system.
  * **Ensure High-Quality Image Capture**: Make sure the image captured during login is clear and well-lit. Avoid blurry or low-quality images by keeping the camera steady and ensuring proper lighting.
