DESCRIPTION
The PelcoNet NET4001A Transmission System is a network video server whose primary purpose is to encode and decode live video, audio,
and control data for transmission over existing Ethernet computer networks (either intranet or Internet) using the TCP/IP protocol. You can
view the pictures on a CCTV or PC monitor.

The NET4001A functions as a transmitter/receiver and is the only unit required to use the PelcoNet NET4001A transmission system. The
NET4001A connects any NTSC or PAL video sources (cameras, for example) to the computer network.
NET4001A connects any NTSC or PAL video sources (cameras, for example) to the computer network.
Depending on how you want to display the video, you can use a NET4001A as a transmitter with a PC or a NET4001A as a receiver. There
are two ways to display remote video:
are two ways to display remote video:
•
Web browser using any PC on the network to display the video
•
A NET4001A (as a receiver) with attached standard NTSC or PAL monitor
Two NET4001A units (as transmitter and receiver) can form a standalone system for data transfer without a PC.
Transmitters and receivers are identified by IP addresses, just like any other equipment connected to a computer network.
There is a bi-directional serial interface for remote control of peripherals like PTZ cameras. This interface can also transmit transparent
data. The NET4001A transmits full-duplex audio.
data. The NET4001A transmits full-duplex audio.
In appropriately configured networks, the multicast function permits simultaneous video transmission in real time to several receivers. For
this to work, the UDP and IGMP multicasting protocols must be implemented in the network.

The NET4001A incorporates dual processors. It operates with the MPEG-1, MPEG-2, and MPEG-4 video compression standards. MPEG-2
encoding allows the data bit rate to remain low even with high image quality. Also, it can be matched into the local environment within
wide limits. In this process, simultaneous encoding of the video signal according to MPEG-4 is supported so concurrent transmission using
low bandwidth (for example, for Internet streaming) is possible. This flexibility lets you view a camera in one compression standard, for
example, while recording in another compression standard if you wish.
