Frequently Asked Questions
Symptoms, Possible Causes, and Remedial Action
Problems setting the IP address
The camera is located on a different subnet
If the IP address intended for the camera and the IP address of your computer are located on different subnets, you will not be
able to set the IP address. Contact your network administrator to obtain an appropriate IP address.
The IP address is being used by another device
Disconnect the camera from the network. Run the Ping command. (In a Command/DOS window, type ping and the IP address
of the unit).
If you receive: Reply from <IP address>: bytes = 32; time = 10 ms..... - this means that the IP address may already be in use by
another device on your network. You must obtain a new IP address and reinstall the unit.
If you see: Request timed out - this means that the IP address is available for use with your camera. In this case, check all
cabling and reinstall the unit.
Possible IP address conflict with another device on the same subnet
The static IP address in the camera is used before the DHCP server sets a dynamic address. This means that if the same default
static IP address is also used by another device, there may be problems accessing the camera. To avoid this, set the static IP
address
to 0.0.0.0.
The camera cannot be accessed from a browser
The IP address has been changed by DHCP
If the camera and client are on the same network, run the IP Discovery Utility to locate the camera.
Identify the camera using its model or serial number
Alternatively:
1) Move the camera to an isolated network or to one with no DHCP or BOOTP server. Set the IP address again, using the IP
Discovery Utility (see the Installation Guide) or the ARP/Ping commands.
2) Access the unit and disable DHCP in the TCP/IP settings. Return the unit to the main network. The unit now has a fixed IP
address that will not change.
3) As an alternative to 2), if dynamic IP address via DHCP or BOOTP is required, select the required service and then configure
IP address change notification from the network settings.
Return the unit to the main network. The unit now has a dynamic IP address, but will notify you if the address changes.
Other networking problems
Test the network cable by connecting it to another network device, then Ping that device from your workstation. See
instructions above.
Camera is accessible locally, but not externally
Broadband router configuration
To configure your broadband router to allow incoming data traffic to the camera, enable the NAT port forwarding feature
which will configures the router to allow access to the camera.
Firewall protection
Check the Internet firewall with your system administrator.
Default routers required
Check if you need to configure the default router settings.
Problems with the H.264/MJPEG format
No H.264/MJPEG displayed in the client
Check with your network administrator to see if there is a firewall preventing viewing.
Poor rendering of H.264/MPEG-4 images
Color depth set incorrectly on clients. Set to 16-bit or 32-bit color.
Ensure that your graphics card is using the latest device driver. The latest drivers can usually be downloaded from the
manufacturer's web site.
Color saturation is different in H.264 and Motion JPEG
Modify the settings for your graphics adapter. Please see the adapter's documentation for more information.
