Frequently Asked Questions

Q: What is the maximum number of users that can be allowed to access DCS-6620
simultaneously?
A: The maximum number of users that can log onto the PTZ Internet Camera at the same
time is 10. Please keep in mind the overall performance of the transmission speed will slow
down when many users are logged on.
Q: Can the PTZ Internet Camera be used outdoors?
A: The PTZ Internet Camera is not weatherproof. It needs to be equipped with a
weatherproof case to be used outdoors and it is not recommended.
Q: Can the PTZ 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. The
DCS-6620 uses port 5002 for streaming audio and port 5003 for streaming video. These
ports (or the ports you specify from the Advanced Tab in the Configuration screen if you
change the default ports) need to be opened on the firewall. Please refer to manual for
more information.
Q: Why am I unable to access the PTZ Internet Camera from a Web browser?
A: If a router or firewall is used on the network, the correct ports for the DCS-6620 may not
be configured on the router or firewall. To correct the problem, you need to determine if the
DCS-6620 is behind a router or firewall and if the router or firewall is properly configured for
the ports the DCS-6620 is using. Refer to manual help in opening the correct ports on a
router or firewall for use with the DCS-6620.
