TROUBLESHOOTING
PROBLEM
I can't access the camera from a
web browser.
Viewer got disconnected during
monitoring.
I cannot connect to the system using
a tab browser of Internet Explorer
7.0.
The camera connected to the
network is not detected in the IP
installer program.
Images overlap.
No image appears.
I enabled Motion Detection Feature
under Motion Detection, but .jpg fi les
are not getting sent over FTP/SMTP
even after motion detection occurs
at the camera.
Is it possible to confi gure Motion
Zone with Motion Detection Feature
disabled?
A motion event took place but didn't
trigger an alarm.
• Check to make sure that the camera's Network settings are appropriate.
• Check to make sure that all network cables have been connected properly.
• If connected using DHCP, verify that the camera is able to acquire dynamic IP addresses
without any problem.
• If connected using a DDNS URL, verify that the MAC address has been properly entered.
• If the camera is connected to an xDSL network, ensure that Bandwidth is set to less than
600Kbps. Because xDSL offers slow connection speed, setting Bandwidth high results in
network load and hinder network connection.
• If the camera is connected to a router, verify that port forwarding is properly confi gured.
• Connected Viewers become disconnected upon any change to camera or network confi gurations.
• Check all network connections.
• If the camera is connected over an xDSL network, it's possible for Viewer to disconnect
under poor network conditions.
• 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.
• Turn off the fi rewall settings on your PC and then search the camera again.
• 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.
• 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.
• Verify the settings in the following sequence:
A. NTP must be properly confi gured.
B. Motion Detection Feature must be enabled.
C. Alarm Video Transmission must be enabled.
D. Check for scheduling confl ict.
• Yes. Motion Zone can be confi gured independently of whether or not Motion Detection Feature
is in use.
• Check alarm output port settings.
