There are three scenarios for troubleshooting:
|
For static IP address users: Most likely, you have full
control of your router and firewall that are connected to the
internet. All you need is to set up your router ports
according to FAQ 12, log-on from remote with a JAVA enabled
browser using your static IP address, and you will be able to
see your jpeg or mpeg4 GeoVision video. |
|
|
For "fairly stable" dynamic IP address users: Most likely, you
are using a cable modem or DSL. They are usually set up as if
you are on a local network (your neighbors share the network).
IP address changes only when routers are re-configured
(typically when they add new subscribers.) This network has
gateway and firewall to the Internet. Under this environment,
you can call your network supplier and ask them to open up the
ports as listed on FAQ 12. Moreover, you would have to be sure
that you have tested your "dynamic IP address" to be correct.
Then, you can try to connect from outside of your LAN
using an JAVA enabled browser. If you have problems using a JAVA
enabled browser to view the video, please trouble shoot
following these steps:
|
Log onto the demo page from Geovision. Make sure you can see
the video using JPEG and mpeg4. This verifies your browser
works OK. (The Geovision demo site is on all of our Geovision
web pages, their office hours are 12 hours ahead of Eastern
time. So, try them in the evenings.) |
|
If your IP address is NOT correct, you will get the message
"IP address not found". Check with your network provider the
right gateway and IP address. |
|
If your IP is correct but your http port 80 is not opened,
then, you will get a blank html page. Verify with your network
provider to see if http port 80 is opened for transmission. If
not, check on FAQ 5.1. |
|
If you can see JPEG videos but not mpeg4 videos, and that you
have verified that all necessary ports are opened, please
check with FAQ 5.4. You would have to install a router with
the NAT. |
|
|
For users where their dynamic IP address changes every few
hours: You would have to check with your network supplier
whether they would open up the appropriate ports for you as in
FAQ#5.0. Then, install a router and direct all necessary ports
on FAQ#5.0 towards your GeoVision server. Use the DMIP (GVIP)
service as listed in FAQ#5.3 (on the GeoVision manual), or
subscribe to services like "www.no-IP.com" where they can get
around to the dynamic IP problem for you. GeoVision and
no-IP.com put a sub-routine in your computer to check you IP
address. Once it gets changed, it will send the changed message
to their web page. They will track the change for you. Prior to
log in, you check with GeoVision or no-IP.com on your most
current address. No-IP.com also provide you with a web page
service that once you click onto an icon of the web page, it
will route you to the desired IP address. |
