K&F Concept DQ201 Quick Start Manual page 34

Processing Steps of Camera and Wi-Fi connection failure:
1.Please make sure you are using 2.4GHz Wi-Fi. In our experience, most
users fail to connect the WI-Fl because of selecting 5GHz Wi-Fi and
adding the camera incorrectly.
2. Make sure you use the correct Wi-Fi password and a fast Wi-Fi
network.(Note: It requires that the Wi-Fi password doesn't have special
characters such as (/l!@#$))
3. Make sure the QR code on the phone screen is normal and the
distance between the phone and the camera lens is 10-15cm
(3.9-5.9inch) during the scanning process.
4.If none of the above steps take effect, please try to re-download the
APP, restore the product to factory settings, restart the router, and then
add it again.
5.After multiple attempts have failed, please contact customer service:
