Network Requirements
The ViconNet system relies on the network to transfer video, audio and data. To optimize system
performance, the network should be specified and built according to the standard for Ethernet network known
as IEEE802.3. Within this standard, specifications for the following items should be followed:
•
The cable length of any single CAT5 type cable should be 328 ft (100 m) maximum (including
wall to equipment cable lengths).
•
It is highly recommended to use switched hubs, or switches, in place of standard hubs. These intelligent
switches will reduce data collisions on the network and increase throughput.
•
It is also recommended to use a dedicated physical network for video security. It is not recommended to
mix the video security network and a corporate data network, as this will reduce required bandwidth for
video files and, in some instances, breach security. If a separate physical network is not possible, it is
recommended to setup the video network on a different network segment with the use of routers and
addressing schemes.
•
The minimal requirement for an Ethernet network is 100 Mbps and it is recommended to use a Gigabit
Ethernet network (1 Gbps) where possible. Kollector Pro units are provided with a 100 Mbps network card
and Kollector Elite units have an internal 1000 Mbps network card.
•
Test your network performance to assure it is not congested using a network sniffer. Make sure that a
large data chunk PING (ping X.X.X.X –l 30000) from station to station is be stable and without timeouts.
Routers and Firewalls
The ViconNet application utilizes TCP transmission protocol. For supportive tools like remote software
installation, a few UDP ports are also used. The following table lists the protocol and ports currently used by
the application:
Protocol Port #
TCP 4345
TCP 4355
TCP 4356
TCP 4357
TCP 4358
TCP & UDP 4359
TCP 720
TCP 6666
TCP 60000
UDP 7777
The ViconNet IP devices are using Ethernet broadcast for the auto-discovery feature, which allows locating
them in the network even before initial configuration. Please be aware that this mechanism cannot cross the
segment boundary unless you configure your router to forward broadcasts. If the ViconNet application is
installed in a manner that requires it to cross the corporate firewall, it is required to open the ports listed in the
table for the ViconNet systems.
