Troubleshooting - D-Link DCS-3420 Quick Installation Manual

Attach the External Power Supply
Attach the external power supply to the DC power input
connector located on the Internet Camera's back panel
(labeled DC 12V) and connect it to an AC power outlet.
Note: When you have a proper connection, the LED will turn
from red to green. The light may cycle on and off and your
computer may show an intermittent loss of connectivity, this
is normal until you have configured your Internet Camera.

Troubleshooting

1. What is the maximum number of users that can be allowed to access DCS-3420
simultaneously?
The maximum number of users that can log onto the 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.
2. Can the Internet Camera be used outdoors?
The Internet Camera is not weatherproof. It needs to be equipped with a weatherproof
case to be used outdoors and it is not recommended.
3. Can the Internet Camera be setup as a PC-cam on a computer?
No, the DCS-3420 Internet Camera is used only on an wireless 802.11g, Ethernet or
Fast Ethernet network.
4. Can the DCS-3420 be installed and work if a firewall exists on the network?
If a firewall exists on the network, port 80 is open for ordinary data communication. The
DCS-3420 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.
5. Why does the Internet Camera work locally but not externally?
This might be caused by network firewall protection. The firewall may need to have
some settings changed in order for the Internet Camera to be accessible outside your
local LAN. Check with the Network Administrator for your network.
Make sure that the Internet Camera isn't conflicting with any Web server you may have
running on your network.
The default router setting might be a possible reason. Check that the configuration of the
router settings allow the Internet Camera to be accessed outside your local LAN.
