Q: Can the HNC300/HNC320G be setup as a PC camera on the computer?
A: No, the HNC300/HNC320G is an Internet/Network Camera and can only be used on Ethernet and Fast Ethernet
networks. The HNC320G can also be used in wireless networks.
Q: Can the HNC300/HNC320G be connected on the network if it consists of only private IP addresses?
A: The HNC300/HNC320G can be connected to a LAN with private IP addresses.
Q: Can the HNC300/HNC320G be installed and function properly if a firewall exists on the network?
A: If a firewall exists on the network, port 80 is open for ordinary data communication. However, since the
HNC300/HNC320G transmits image data, the default port 8481 is also required. Therefore, it is necessary to open port
8481 on the network for remote users to access the HNC300/HNC320G.
B. Ping Your IP Address
The PING (Packet Internet Groper) command can determine whether a specific IP address is accessible by sending a
packet to the specific address and waiting for a reply. It can also provide a very useful tool to confirm if the IP address
conflicts with the HNC300/HNC320G on the network.
Follow the step-by-step procedure below to utilize the PING command. But first you must disconnect the
HNC300/HNC320G from the network.
Start a DOS window.
Type “ping a.b.c.d”, where “a.b.c.d” is the IP address of the network camera.
C. Troubleshooting
Given below are some helpful explanations to the causes of potential problems that might arise with the
HNC300/HNC320G.
Q: I cannot access the Internet Camera from a web browser.
A1: The possible cause might be the network camera’s IP Address if it conflicts with another device. To correct the
possible problem, you need to first disconnect the Internet Camera from the network. Then run the PING utility (follow
the instructions in Appendix B - PING Your IP Address).
A2: Another possible reason is the IP Address is located on a different subnet. To fix the problem, run the PING utility
(follow the instructions in Appendix B - PING Your IP Address). If the utility returns “no response” or similar, the
finding is probably correct, then you should proceed as follows:
In Windows 95/98/2000 and Windows NT, double-check that the IP Address of the camera is within the same subnet as
your workstation.
Click “Start”, “Setting”, “Control Panel”, and the “Network” icon.
Select TCP/IP from the “Network” dialog box, and from the “TCP/IP Properties” dialog box, click on “Specify an IP
address”.
