INSTALLATION TIPS
Mount the system where it can
easily be reached to reboot.
To access advanced features, the
system must be connected to a
public internet network ensuring
wireless phones can see wired local
servers.
Access points need to be 801.11n or
better; dual band preferred.
If you want a static IP address,
please request prior to shipment.
Avoid mesh or multi-hop networks
and avoid crowded wi-fi frequencies.
Perform a site survey and check
interference issues before finalizing
the installation.
*2.4 GHz wi-fi has only three non-over
-
lapping channels.
