Multi-Cam
Solution
Though Watcher by
itself is basically a single-cam
software. There are two solutions
to use Watcher for multiple camera
scenario.
Solution 1:
Multiple Watcher Installation
(an inexpensive and functional
multi-cam solution)
Solution 2: Use one
Watcher with Video Source
Switchable Capture
board.
Multiple Watcher
Installation:
1. Suppose you have
two cameras. You can install Watcher
software twice into different
folders and different program
groups, i.e. as if they are two
totally unrelated software. If you
are not too sure how to do it,
please follow the steps
here.
2. Run the two
installed Watcher software. (Please
remember not to run the same
Watcher twice.) You can go to
the Video Source menu to select
your desired video source for each
different running Watcher instance.
Different Watcher instance now
connects to different cameras, and
each of them functions perfectly!
To keep a consistent log file
management, we recommend you to
always associate one Watcher
instance with one particular
camera. Watcher has the ability
to remember the last camera it
connects to and will automatically
tries to connect to this camera
upon program starts. However, the
assumption is that different
cameras connect to different
drivers. If a same driver is used
for two cameras, Watcher will not
be able to remember the camera.
- 3. If you put Watcher in "Broadcasting to Local Web Server"
mode, you should go to Watcher Settings->Internal Web Server, and
specify a different port (which the internal web server listens on) for
different Watcher instances. For example, suppose you specify 1234 as the
web server's port for Watcher Instance 1, and when you use internet
explorer to view the camera connected by Watcher Instance 1, you can put
the address as "http://xxx.xxx.xxx.xxx:1234" where
xxx.xxx.xxx.xxx is Watcher PC's IP address.
4. For Remote
Surveillance purpose,
RemoteView can now connect to
different Watchers running on the
same PC using TCP/IP
connection. This is achieved by
specifying the communication port
number at Watcher end and
RemoteView can then use different
port number to connect to different
Watcher. With this capability, our
software now is truly the most
inexpensive and fully functional
solution for multi-cam
application.
Further more, this
is a perfect solution for those
people having two or more webcams,
and because they share the same
license, you
only need to purchase one copy of
Watcher to get all of them
registered!
Use one Watcher with
Video Source Switchable Capture
board:
Another solution
for multi-cam is to use a
switchable video capture card. This
type of capture card can be
connected to to multiple analog
cameras, with the switching
function built inside the board,
multiple video sources will be
combined into one single video
stream. So from Watcher's point of
view, it sees only one video
stream, and yet, you are watching
multiple video sources at the same
time!
Besides, with our
specially made monitoring
technology, Watcher can even
monitor motions with the switching
video sources sent from these types
of switching capture device. It can
distinguish between real motion and
video switching.
There are many
switchable video capture card (or
router) in the market. They should
be able to work with Watcher as
long as they are either WDM
(Windows Driver Model) or VfW
(video for windows) compatible.
Most of such devices supports these
two popular drivers.
One of the examples
is
Videum 4100 from Winnov, a
high-performance capture board with
four switchable video sources.
