When watching the live broadcast, the image and sound are delayed and the troubleshooting method:

1. The router network problem, the router bandwidth is insufficient, check method: whether the mobile phone can play network video smoothly after connecting the router, or whether the Internet speed of the router is normal through the speed measurement software?

2. The installation location of the device is too far away from the router, and the WIFI signal is weak due to the installation location of the device. Please install the device close to the router.

3. If the mobile phone is connected to the router, please move the mobile phone close to the router to watch the live broadcast of the camera. If the mobile phone uses a 4G network, please check whether the mobile phone can smoothly watch the network video or speed the mobile Internet speed through the speed measurement software.

4. Manually reset the device, directly search the device through the “AP mode” of the APP, and check whether the image is smooth in AP mode? If it is smooth, it is caused by network problems. If it is not smooth, it is a hardware failure of the device. Please resolve it after sales.

If none of the above methods work, please power off and restart the router once.
