Q: Can the Internet Camera be installed and work 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 Internet
Camera transmits image data, the default port 8481 is also
required. Therefore, it is necessary to open port 8481 of the
network for remote users to access the Internet Camera.

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

Internet Camera over the network.
Follow the step-by-step procedure below to utilize the PING
command. However, you must disconnect the Internet Camera
from the network first.
Start a DOS window.
Type ping x.x.x.x, where x.x.x.x is the IP address of the Internet
