Cause/solution
• When logged in with "Limited" user account of
Windows operating system, images will not be dis-
played since the active X control may not be installed
correctly.
Log in with "Computer administrator" user account.
• When the image compression method of all cameras
in use is not the same, performance may become
lower. (Refresh of images will be unstable.)
• The configured settings for transmission rate/record-
ing rate may be beyond the maximum network perfor-
mance.
Lower the value/rate of the settings relating to the net-
work such as the transmission rate, recording rate,
etc.
• The line speed settings may be not the same between
the unit and the hub, for example, 100M BASE-TX
Full for the unit and 100M BASE-TX half, etc.
Some hubs change the line speed automatically
depending on the network traffic and it may cause
configuration errors. Check the line speed settings of
both the unit and the hub, and configure the line
speed setting of both to conform them. (It is recom-
mended to set the line speed setting of all recorders,
PCs and habs to "100-FULL".)
• Are the settings of the network camera set correctly?
Check the model of the set camera on the setup
menu ("Camera" - "NW Camera Setup").
• Are the user ID and the password for the network
camera set correctly?
Check if the user ID and password are set correctly
on the setup menu ("Camera" - "NW Camera Setup").
• Change the port number for the camera, and then
click the [SETUP] button again.
