I cannot connect to the system
using a tab browser of Internet
Explorer 7.0.
When you try to connect to the system using a tab browser, the same
cookie information is shared, resulting in errors when connected.
Therefore, instead of using a tab browser, open a new browser window
to connect to the system.
y
The camera connected to the
network is not detected in the IP
installer program.
Turn off the firewall settings on your PC and then search the camera
again.
y
Images overlap.
Check whether two or more cameras are set to a single multicast address
instead of different addresses. If a single address is used for multiple
cameras, the images may overlap.
y
No image appears.
If the transmission method is set to multicast, check whether there is a
router that supports multicast in the LAN the camera is connected to.
