1. Ensure that you have connected your mobile device to the correct band. For EZVIZ devices support 2.4G Wi-Fi only, you must connect your mobile phone to 2.4G Wi-Fi.
2. Ensure that your Wi-Fi network connection is good. Most EZVIZ devices perform better when the upload speed is greater than 2 Mbps for each camera.
3. Ensure that your Wi-Fi network signal is good. Try to avoid obstacles and interferences such as walls, elevators, microwaves, washing machines, and Bluetooth devices.
