WHAT IS THE PELCONET NET104A TRANSMISSION SYSTEM?
The PelcoNet NET104A Transmission System is technology that lets you view video from four
sources in real time across a LAN (local area network) and even WANs (wide area networks). This
technology is based on the TCP/IP protocol suite and Ethernet technology, providing compatibility
with today’s networking standards.
(See the
Glossary
section for definitions of terms used in this manual.)
HOW DO LANs AND WANs WORK?
•A LAN consists of multiple computers connected together, sharing information. This
information could be files, e-mail, printers, or–with the PelcoNet NET104A Transmission
System–even live video and audio.
•A WAN consists of multiple LANs connected over a great distance (for example, the Internet).
• In any network environment, each computer needs an address so other computers on the
network know how to reach it.
It is similar to a city with street addresses. For the post office to deliver mail to your house, you
need a unique street address for the mail carrier to find you. A network is like the city. Like a
street address, the IP address on your computer is your address on the network. The IP address
is how other computers can find you on the network.
Remember that the IP address must be unique on the network.
• When there are multiple networks and you are using the TCP/IP protocol, there must be a way
to communicate between the two networks. A physical device called a router is required. The
router’s IP address is referred to as the default gateway IP address.
•A cable that connects one computer to another is like a city street you can use to get from one
house to another. The cable lets you communicate with each other on the network. This cable
is Category 5 cable with RJ-45 connectors at each end. (It looks like a phone cord, only slightly
larger.)
WHO SHOULD INSTALL THE PELCONET NET104A TRANSMISSION
SYSTEM?
NOTE: Consult your network administrator if you need help.
Installation is a matter of configuring an IP address using a standard terminal program or any Internet
browser and connecting the PelcoNet NET104A Transmission System to the Ethernet network. You
should have the following background and experience to configure and install these units:
•Working knowledge of basic network management concepts and terminology
•Working knowledge of tools and procedures for installing and operating sensitive electronic
equipment
