the factory defaults include TCP/IP filtering = enabled,
and only the non-optional ports indicated above are
allowed (you can add more ports if needed). NetVision
should also work fine with TCP/IP filtering disabled and
all ports permitted, but that could leave the system
vulnerable for hacker attacks and thus reduce overall
security.

To Connect via the Internet
For internet connectivity, the Video Server and
remote stations must have access to the
internet (use the CD and/or instructions
supplied by the internet service provider).
Note: For cameras and recorded videos to be
available, the Video Server and NetVision software
must be running, and the Video Server must have
permanent access to the internet (always on-line).
TechTip: Due to the amount of data contained in
video images, a high-speed (non-dial-up)
connection is best.
As well, the Video Server must have a fixed IP
address, and this value must be known by
remote operators.
Note: Due to speed and reliability considerations,
dial-up connections are generally not
recommended. Use a faster connection if you have
a choice.
