System Overview
1.1
System Overview:
Netvision™ is a remote digital
video surveillance capture and
reporting system accessible by
LAN/WAN, the Internet, or through
a dial-up networking connection.
The two main components of the
system are the Video Server (with
cameras) and remote stations.
The Video Server collects and
digitally records video input from
video cameras and allows viewing
it at remote surveillance stations
using an IP link (LAN/WAN,
internet, or dial-up networking).
Remote surveillance Stations are
video receivers that function as monitoring
consoles and enable a variety of
administrative, alarm and monitoring
functions. Remote monitoring tasks can
be carried out from anywhere you have
access to your network, the internet, or a
telephone.
The Video Server includes a computer, video
capture board(s), cameras, and software. Remote
surveillance stations include software typically
running on an existing/locally sourced Windows PC.
1.2
Additional components include:
• Video cameras (up to 16--using four capture
boards). Any of them can include PTZ
support.
Eight ports/PTZ protocols are supported, plus PTZ-
cascading (e.g., Canon VC-C4).
• Input / Output wiring harness;
• Microphone(s) for audio support at
camera(s)--can be monitored at remote
stations as well.
Tip: Current video server units typically include up
to 5 audio inputs.

Note: Due to speed and reliability
considerations, dial-up connections are
NOT recommended. Use a faster
connection if you have a choice.

supporting 4, 8, or 16 cameras.
