Version 1.5 for Windows (98/NT/ME/2000/XP)
Release 13. July 2004
CamUniversal works with NetCams (IP-Cams), WebCams and additional
video devices which are using a driver for Windows.
WebCams and similar video devices like TV Tuner cards, capture
cards, graphic cards with a capture input etc. are working
with CamUniversal if there is an actual driver for Windows
available. CamUniversal uses the DirectShow component of DirectX
for the work with these devices. So all functions and settings
which are coming with the video device drivers are usable.
An advantage against other WebCam products is the possibility
to work with all connected and installed video devices simultaneously.
CamUniversal needs for the working with NetCams their
IP addresses. From these IP addresses the program receives
the actual camera picture. Example: http://192.168.110.124/picture.jpg
If you are receiving more pictures as your camera is able
to generate (the receiving intervall is set to every 0.5 sec,
but your camera captures pictures only every 1.0 sec), you
receive often the same picture twice. So it makes no sense
to receive more pictures as there are new ones available.
Look at the network camera manual for possible capture intervals!
The resolution of the received picture
is not limited. But if the program receives a picture which
has a resolution of 640x480 pixels, it must transfer much
more pixels as if the picture would have only 320x240 pixels
and the program has to test 4 times the amount of pixels within
the intern motion detector difference test.
CamUniversal allows the using of all installed video devices,
video codecs, audio devices and audio codecs.
But not all devices and codecs are working together! Furthermore
some codecs changes the selected frames by second for the
video recording by themselves and other codecs don't allow
to record a video and watch a preview parallel.
All digital cameras generates different pictures from the
same situation also if there are no changes. If you algin
your camera to view on a wall where nothing is moving and
let the motion detection run, you get little picture differences,
because the generated pictures are different. This happens
on the way from the analog world into the digital picture
from your camera. To see these differences (not only these,
but all differences) you can select in the program to show
you the difference window. This is a good way to see how good
or bad your camera works. To reduce this differences which
are in reality not existing, you have to adjust the pixel
