Symptom

Possible Cause/Solution

 

Network bandwidth is insufficient.

 

Without sufficient bandwidth, video quality will deteriorate and image errors like

 

pixilation or frame-drop may occur. When you view your camera remotely from

 

the

 

Internet, your camera needs sufficient upload bandwidth to transmit video stream

 

and you need sufficient download bandwidth to download video stream at the

 

remote location.

 

To gain satisfactory video quality, ensure there is sufficient upload bandwidth

Part of the image becomes

available to your network camera by taking the following actions:

pixilated/Image artifacts

 

appear

1. Contact your Internet Service Provider (ISP) to confirm the upload/download

 

speed limit of your service. If the bit rate of the video stream is set at 512Kbps

 

or higher but your Internet service only provides a max. of 512Kbps for upload

 

bandwidth, then try to lower the bit rate setting in [Setup] > [Video].

 

2. Run a network speed diagnostics on WebVUer to determine the bandwidth

 

level of the currently connected network. To do so, log in to your camera using

 

WebVUer and go to [Setup] > [Network] > [Network Bandwidth]. When the

 

speed

 

diagnostics is done, the WebVUer will advise you of the appropriate setting.

 

Consider the following actions to ensure sufficient download bandwidth at your

 

remote viewing location:

 

1. Contact your Internet Service Provider (ISP) to confirm the upload/download

 

speed limit of your service. If the bit rate of the video stream is set at 3Mbps

 

or higher but your Internet service only provides a max. of 2Mbps download

 

bandwidth, then try to lower the bit rate setting in [Setup] > [Video].

 

2. Upgrade to a Gigabit network switch. Regular 10/100 Mbps network switches

 

cannot handle multiple megapixel streams.

 

3. While you are viewing the network camera remotely, shutting down any other

 

applications that are also consuming network bandwidth in the background.

Gray images are seen

Network quality is insufficient.

repeatedly

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:

 

Test your bandwidth to determine whether this problem is the result of poor

 

network quality. Alternatively, 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, your wireless signal strength could

 

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

 

You can check your 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 is too low, you may have to place your

 

wireless Access Point in a different location, use a wireless repeater, or remove

 

obstacles between the camera and the wireless AP.

Ghost image is seen

Network quality is too low.

 

This is a common problem when the network’s quality is low or the video setting is

 

too high. Lower your camera’s video bit rate and see if the problem continues.
