If the camera cannot read the QR code: How to adjust the focus

Issue Description

• The camera cannot read the QR code

• The camera LED remains flashing red during setup and does not change

Possible Cause of Issue

The GRAN EYE camera has a structure that allows focus adjustment by rotating the lens.

Therefore, when removing the lens cap, the lens may rotate slightly, causing the focus to shift.

If the focus is off, the QR code cannot be recognized properly.

Solutions

Focus Adjustment Procedure

1. Rotate the lens clockwise and tighten it until there is no gap between the lens and the body.

2. From there, slowly loosen it 1-2 turns counterclockwise.

3. Point the QR code toward the camera and try scanning it while moving it closer and farther away.

4. If it does not scan, gradually loosen the lens (counterclockwise) and hold the QR code up again.

5. When scanning is successful, the camera LED will flash green.

Tips if it doesn't work

• Set the screen brightness to maximum on the device displaying the QR code

• Turn OFF the device's night mode/blue light filter

• Point the camera directly at the QR code and minimize hand shake

• Gradually adjust the distance, as it may not scan if too close or too far away

If the issue persists
