Try these steps:

1. Make sure your app is version 6.0.10 or above

2. After scanning the QR code, confirm the device makes a "beep beep" sound

3. Try binding using your phone's hotspot, then update the camera to the latest firmware

4. During binding, keep the device 1-2m away from the HomeBase/router

5. If using HBmini: use a 5V/2A power adapter

6. Can't scan the QR code on your phone? Check if your phone is in dark mode — switch to light mode or increase screen brightness

7. Make sure the QR code is fully displayed and not blocked on your screen

8. This device only supports 2.4G WiFi. If your router uses a mixed 5G/2.4G band, remove "5G" from the WiFi name

9. Watch the binding tutorial video and follow the steps

If the issue persists:

Please contact support and have the following ready:

• Your device SN (serial number)
