Symptom Possible Cause/Solution

Gray images are seen

repeatedly

The network quality is not good.

Seeing lots of gray images in live view mode indicates that many data packets which

carry video data are dropped during the transmission. This might be caused by network

congestion, wireless congestion, or the limited upload/download bandwidth of your

network. To measure the upload/download capability of your network, you can use

eitherthe“NetworkBandwidth”testingtoolinthenetworksettingspage,orvisit

speedtest.net(http://speedtest.net/).

When using wired connection:

Please test your bandwidth in the way we mentioned above to determine whether this

has been the result of poor network quality. Or try connecting your camera to your

viewing computer directly to see if there are any faulty devices on your network.

When using wireless connection:

Besides the possible network bandwidth issue, the wireless signal strength could also

come into play. Low wireless signal strength may also lead to the same problem. You can

check the wireless signal strength in the camera’s network settings page. The wireless

signal level seen in the network settings is measured in dBm. To gain the optimal

wireless connection quality, a signal level greater than -60 dBm is recommended. When

the signal level gets too low, you may have to place your wireless Access Point in a

dierent location, use a wireless repeater, or remove obstacles between the camera and

the wireless AP.

A warning message

saying “Your video

quality is too high

for your internet

bandwidth” popped

Network quality is not good enough.

This means the camera’s browser interface, WebVUer, could not receive a steady stream

of video data from your camera. The loss of video data might also be caused by network

congestion or insucient bandwidth. Please refer to other related troubleshooting tips.

Additionally, if the CPU usage on your viewing computer is too high, the same warning

message will be showed. You can monitor the CPU usage by right clicking on your

Windowstaskbarandchoose“taskmanager”,andthenclickthePerformancetab.
