Appendix C: Troubleshooting
This appendix provides useful information to help you to resolve any difficulty you might have with your Pro Series Network Camera. Fault symptoms, possible causes and remedial actions are provided within a quick reference table.
PINGing Your IP address
By sending a packet to the specified address and waiting for a reply, the PING (packet Internet grouper) can determine whether a specific IP address is accessible. It also provides a particularly useful method for confirming addressing conflicts with your Pro Series Network Camera on the network.
After disconnecting your camera, follow the instructions below in association with Symptoms, Possible Causes and Remedial Actions and run the PING utility to troubleshoot TCP/IP problems on your network.
1.Start a DOS window
2.Type ping x.x.x.x, where x.x.x.x is the IP address of the camera.
3.The subsequent replies will provide an explanation as to the cause of the problem. Replies can be interpreted as defined in the table below:
PING reply | Interpretation and recommendation | |
bytes = 32 time = 2 ms | The IP address is already used and cannot be used again. | |
You must obtain a new IP address. | ||
| ||
Destination host unreachable | MPEG4 Network Camera is not accessible within your subnet. | |
You must obtain a new IP address. | ||
Request timed out | This IP address is not used by anyone and is available for use | |
with your Pro Series Network Camera. | ||

| In Windows 95/98 or Windows 2000/XP/Vista, check that the | |
|
| IP address for your camera is within the same subnet as | |
|
| your workstation: | |
|
| 1. | Click "Start," "Settings," "Control Panel" and "Network." |
|
| 2. | Specify the TCP/IP adapter and click on "Properties." In |
|
| Properties, click "IP address." | |
|
| 3. | Check that the first 3 numbers within the IP address of |
|
| your camera match the first 3 of your workstation. If not, | |
|
| your camera may be on a different subnet and the IP | |
|
| address cannot be set from this workstation. You must set | |
|
| the IP address for the camera from a workstation on the | |
|
