TROUBLESHOOTING GUIDE
Q1. There is no live picture sometimes.
• It may be caused by the poor network due to Wifi interference, obstacle blocking and
so on.
• When you are viewing the live picture from the Cloud, please make sure the
network connection between the NVR and router works well. At the same
time, make sure the router provides enough upload bandwidth. To improve
the quality of network, you can reboot the router regularly.
• When you are viewing the live picture from the same network as your
router’s, please make sure the network connection between the camera
and NVR works well. You can check the quality of the Wifi signal from live
interface.
• If the Wifi signal is good but the live picture of all the
channels still buffers and lags, another device may
interfere the connection between the NVR and cameras.
Please try to get rid of it or change the Wifi channel from
System Setup > Network Setup > Wifi Setup > Wifi Channel.
• If the Wifi signal of one channel is poor, move the camera
close to the NVR to check whether the strength of Wifi
signal is stronger and make sure the antenna of the
camera is fixed well and pointed at the right direction. If
the Wifi signal of all channels is poor, please slowly move
the antennas of the NVR until they point at the right
direction as mentioned in the section of Adjust the
antennas to the appropriate angle on page 28.

Q2. There is no live picture when using a browser to log in to the NVR.
• Please go to System Setup > Network Setup > Web port to check whether the
Web port has been changed from 80 to another number, e.g. 1111. If yes, input
the IP address and :1111 into IE to visit. For example, the IP address is
192.168.251.106 and the Web port is 1111, then please input
http://192.168.251.106:1111.
• Make sure you have installed the Web View Control correctly on your IE browser.
