Troubleshooting
1. What is the maximum number of users that can be allowed to access DCS-7510
simultaneously?
the maximum number of users that can log onto the Network Camera at the same time is
10. Please keep in mind that the overall performance of the transmission speed will slow
down when a large number of users are logged on.
2. What algorithm is used to compress the digital image?
mPEG-4 and mJPEG are used to provide high quality images at low bandwidths.
3. Can the DCS-7510 be installed and work if a firewall exists on the network?
If a firewall exists on the network, port 80 needs to be opened for ordinary data
communication, streaming audio, streaming video. the DCS-7510 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, needs to be opened.
4. Why am I unable to access the DCS-7510 from a Web browser?
Ensure that the ports configured for the DCS-7510 on the router or firewall are correct. In
order to do that, you need to determine if the DCS-7510 is behind a router or firewall and
then properly configure the ports of your DCS-7510. Other possible problems might be
due to the network cable. try replacing your network cable. test the network interface of
the product by connecting a local computer to the unit, with an Ethernet crossover cable.
If the problem is not solved the Network Camera might be faulty.
5. Why does the Network Camera work locally but not externally?
This might be caused by the firewall protection on your network. You may have to change
the firewall settings in order for the Network Camera to be accessible outside your local
LAN. Check with the Network Administrator and ensure that the Network 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 Network Camera to be accessed outside your local LAN.
