What kind of photo is needed so that the device can recognize an employee? / Photo requirements

For the Clockster facial recognition device to accurately identify an employee, it’s important to upload a high-quality photo that meets all system requirements. Below are the exact guidelines to help you avoid recognition errors:

Photo requirements for facial recognition:

  1. Face position must be strictly in the center of the frame.

    • The head should not be tilted, turned sideways, or thrown back.

    • The gaze should be directed straight at the camera.

  2. Background – light and neutral.

    • The background must be solid and neutral. Ideally light (white or gray), without objects, shadows, or textures behind the person.

  3. Photo type:

    • The photo should be frontal, like a passport photo.

    • Ears and forehead must be visible.

    • The face should occupy about 70–80% of the frame.

  4. Accessories and clothing:

    • No headwear, glasses, masks, or headphones.
      Exception: Religious head coverings are allowed if they do not cover the face.

    • Sunglasses and even transparent glasses are not recommended.

    • Clothing — no hoods or scarves.

    • The neck and shoulders should be visible so as not to interfere with the recognition algorithm.

  5. Lighting:

    • Good lighting.

    • No glare, strong shadows, or overexposure.

    • Lighting should be even, without colored lamps or neon effects.

  6. Photo relevance:

    • The photo should be recent (not older than 1 year) and reflect the employee’s current appearance.


File format and size:

  • Format: JPG or PNG

  • File size: up to 5 MB

  • Recommended resolution: 480×640 px or higher


🔄 Tip: If the employee has significantly changed their appearance (e.g., new hairstyle, beard, weight change), it’s best to update the photo in the system for more reliable biometric recognition.
