First of all, if anyone can post the URL's of any good webcam-forums -
please do.

I'm having problems seeing real-time streaming from some network IP
cameras from outside my local network. These are cameras that
typically seem to run a linux-based web server and offer either
active-X or Java based viewing choices, but I'm finding that either I
don't get an image or I get a static (not streaming image) when
connecting to the camera from outside my local network.

One particular camera I'm working on is the TRENDnet TV-IP201.

When turning on the java debugger I can see that there are errors, but
I'm running the latest version of jscript and Sun Java JRE, so I don't
know WTF is going on here.

Can't help you with the Java problems, but no doubt some one else will
be able to, but as for good webcam forums....don't think you will find
any of them. Doing a search only results in a lot of porn sites with a
couple of so called 'forums' included and they seem to to take their
content directly from here. However, you could try here:
http://hardware.mcse.ms/Webcams/
A lot of the people who post there also post here. So that site and this
newsgroup seem to be the 'brains trust' of the webcam world! :-) There
are some bright people who post on this newsgroup so I am sure some help
will be forthcoming.
Can't say as I have heard of trendnet cameras and would be interested in
seeing some in 'action'.
Some IP cameras I view don't work or just deliver a static image when
they are supposed to be streaming but I have always put it down to
problems at the other end especially if they work sometimes but not others.

I have that cam in wireless, and another just like it from a diff maker.
Work fine.

Some things I can think off hand ;

In the cam you might want to assign a public DNS IP Address, possibly other
than your isp or local router, as they might not work for joe public.

You need to link the so called activeX pack from a publicly available server
somewhere.

You need to make two "separate" router firewall or server rules locally and
match them in your cam configurations.
1 : Web Server - Default 80 (some isp's block this port, suggest u
change this)
2 : Transfer Image - Default 8481

Something I didn't want to say is that the problem(s) I'm seeing is
only on systems running Windows 98. These are fully updated systems.
For example, at one location I have a system running Win-2k and
another running 98. Both can access the Trendnet camera (located in
another city) but only the 2K machine can reliably get a streaming
picture from it.


I'm using the IP address of the subscriber to which the camera is
connected. The IP address assignments are pretty stable and can last
for weeks.


Can you please explain that item with more detail?


The camera's port has been changed to 85, and the router is routing
port 85 to the camera's LAN ip.


Can you please explain that item with more detail?

PS:

A speed test performed via dslreports indicates that the upload speed
of the DSL connection in question is between 574 to 600 kbps (72 - 75
KB/sec). I don't know if overhead is taken into account or not.

Given that upload bandwidth, how many frames-per-second can I push
through at 320 x 200 and 640 x 480 image resolution?
