Troubleshooting
This section provides useful information and remedies for common situations where problems may be
encountered.
Problem Possible Solution
No network connection
Hardware issues:
Check that the network is working and the unit is powered on.
Check that the network (Ethernet) cable is properly attached to the unit.
Confirm that the network cables are not damaged and replace if
necessary.
IP Address issues:
Change the default IP address/addresses of the unit.
From the PC running the web browser, ping the unit IP address and
confirm that it can be reached.
Confirm that the network settings/firewalls are set according to the
requirements.
The camera might be located on a different subnet. Contact your IT
administrator to get the IP address of the camera.
How do I find IP address
of my unit?
Check the network DHCP server IP address assignments and lease.
Alternatively, move the camera to an isolated network and make sure
camera gets DHCP address and is accessible. Move the camera back
to the network and test it. If you still have issues, reset the camera
physically by pressing the reset button on the rear of the camera and
test the camera again. This will ensure the camera releases the IP
address.
The IP address responds
to a ping on the network
from the workstation but
does not show in the
Discovery List
Disconnect the unit’s Ethernet 10/100 port or turn the power to unit off,
and then ping the IP address again. If the IP address responds, there is
another device using the IP address. Consult with your network
administrator to resolve the conflict.
Check the network port and ensure that it is working OK.
Ensure that the switch ports provide the necessary power.
The unit IP address is in
use by another computer
(collision)
Check the DHCP settings. Obtain a new IP address using DHCP.
Ensure this is a unique IP address.
Alternatively, change the unit IP address after connecting to it directly
(not through the system network).
Cannot log in to the
camera
Check the user name of the user or admin.
Check the password of the user or admin.
No video image displayed
on the main menu or the
view menu of the web
interface
Reset the browser security settings to the default value.
Check that the correct port was configured. The default port is 554.
Poor output video quality
Check that the network cable is connected securely.
Check that the camera settings are correct on the camera and in the
unit.
Check that the camera lens is clean and unobstructed.
Check that the cable length is within specification.
