Introduction
NetVision Video Servers support a number of
methods for viewing cameras, aiming PTZ
cameras, and recording video images directly
through your web browser.
We’ve ‘showcased’ these features through a
demonstration server at:
http://netvisiondemo.verextech.com/links.htm
(notice NO “www”).
See further instructions below for details on
using any of the associated web pages.
28.2
Requirements and Speed
Concerns
The display rate will depend on your
connection speed, and server configuration.
Bandwidth (or framerate) selections are also
provided in each screen to obtain best results.
Accessing the WebCam or WebView ‘page’ on
any server will require a valid remote user
name and password that has access to the
WebCam server (for WebCam), or to the Video
Server (for WebView).
Note: If the HTTP port being used by the NetVision
Video Server is NOT “80”, then any server references
must be appended with a colon plus the actual port
number that is being used (e.g.,
xxx.xxx.xxx.xxx:Port#
). Remote users and the HTTP
port are set through the same screen.

Note: Since this feature works through the NetVision
Video Server, cameras do not need to be IP-
addressable.
28.3
Using WebCam
WebCam works by continuously ‘grabbing’
JPEG images from the NetVision video server.
With a fast connection, this is capable of a
nearly real-time video (from one camera at a
time).
WebCam supports NTSC and PAL cameras,
and allows viewing a camera and taking
‘snapshots’ when desired. WebCam works
directly with your browser, and will not prompt
you to download any additional software.
To access the WebCam feature, you can:
• Select one of the WebCam options from the
demo site (http://netvisiondemo.
verextech.com/ links.htm), or;
• Access the WebCam feature for another
server as follows:
Simple/html version:
http://ServerIPorName/webcam/ index.htm
Java applet version:
http://ServerIPorName/java/webcam/
index.htm
Tip: Remember to include the “:Port#” after the
server name or IP address if the port is not 80.
