VM95
The main control program that runs under XP
is called VM95. It has been written by Erdman
Video Systems and is continuously being developed and updated as
new equipment and capabilities become available. Running in the Windows
environment has allowed VM95 to incorporate and use recently introduced
technology, both in the digital imaging field (Olympus cameras) and
in the communications field (DSL, routers modems TCP/IP). This software
is designed to control digital stills cameras and or IP Network cameras.
VM95 began over 12 years ago as a simple video imaging tool, and has
now evolved into a sophisticated software package that handles video
and digital image acquisition, precise pan/tilt control, image processing,
panorama creation, graphing, uploading, video server activities, remote
control and security monitoring.
- Some unique features are:
- Control of Canon Digital Cameras up to 21 Megapixels
- Precise panning, tilting and zooming both remotely and under schedule
control
- Simultaneous control of up to 4 video cameras
- Total or partial image archiving, both locally and anywhere on the
Internet
- Rotating, cropping and labeling images to get perfect results
- Automatic slideshow preparation for current and archived imagery
- Support for a dual cameras on the pan tilt, one video and one digital
camera
- Windshield wiper/spray system supported in both manual and program
control
- Remote control for authorized users: pan, tilt, zoom, continuous
record mode
- Ability to snap hi resolution shots remotely (via Internet)
- Automatic panorama stitching software
- Information retrieval from other web sites and label images (e.g.
water temp)
- Long digital exposures for low-light, night time monitoring
- Automatic 'problem' detection with auto-reboot and recovery functions
- Additional Standard Features Supported
include:
- Image acquisition at regular intervals
- Automatic Image labeling with date time and user specific information
- Upload imagery at regular intervals
- Incorporates low light video camera for night time observation
- 24/7 recording of video imagery for security purposes
One of the more powerful aspects of VM95
is the scheduling of all its activities. Setting up the schedule can be
as simple as taking 1 shot per day and uploading it, to setting up 3 panoramas,
5 single shots, uploads to 2 different FTP sites, and slideshow preparation
for multiple scenes. Programming the schedule is through a standard Windows
interface, complete with Help files. Additional to this the hardware provides
a number of analogue ports for recording weather data or utilising triggering
devices such as motion detectors. Given the multitude of options available,
and a number of new concepts, Eon-FX encourages taking advantage of their
training courses. All initial setup and configuration is done by Eon-FX
and will be modified to satisfy any late-emerging requirements.
Of course Eon-FX primarily uses this
software to acquire high quality images to generate time-lapse sequences
however, as you can see, this is not the only result that can be achieved.
Normally, VM95 runs its schedule and
uploads all the desired imagery and data to a Website where the results
are displayed to the public. Remote control capabilities have been incorporated
into VM95 which allows authorized users to either 'watch' passively as
the camera system goes about its scheduled activities. In Remote Control,
one can also 'take control' of the camera system, wherein the scheduled
activities are stopped and full control is given to the remote user, allowing
the user to pan, tilt, zoom and take digital shots, all over the Internet.
This type of remote control is not for the public, since the constant
interruptions would prevent carrying out the scheduled activities and
image acquisition for time-lapse sequences would not be achieved. There
is also the consideration of bandwidth, or Internet traffic. At the camera
station, there will be a DSL type connection (at best) and this could
only handle around 10 simultaneous users.
So the important 'final products' of
the camera system are high resolution image acquisition and advanced webcam
functionality. Check out our video
demo and example web page.

VM95 running in Automatic Mode (Web Cam
Mode)
The EVS camera system has 2 fundamentally
modes of operation: Web Cam Mode, and Remote Control Mode. The
most frequently used mode will be Web Cam Mode. The activities carried
out in Web Cam Mode include:
· Automatically moving to preprogrammed
positions
· Capturing, labeling and archiving the images at programmed intervals
and resolutions
· Uploading the desired imagery to the web in the form of individual
images
· Preparing Wide angle composite panoramic views and uploading them
to the Internet
· Preparing slideshows of current images and uploading them
· Maintenance of image space utilization, respecting allotted disk space
limits
· Maintaining a permanent archive of images at the Website
· Preparing slideshows of the permanently archived images and upload
them
Web Cam Mode is programmed using the
scheduling functions of VM95 as discussed above. VM95 normally is in Web
Cam mode when there are no remote users logged on controlling the system.
When remote users log on requesting Full Control, the scheduled activities
stops, and VM95 waits for commands from the remote user. If there is no
activity for 3 minutes, or the remote user logs off, the scheduled activities
resume.
When Web Cam mode is active, authorized remote users can 'spy' on the
camera, watching real time video as it goes through its scheduled activities.
The number of remote users that can control and spy on the camera system
depends on the internet connection present at the camera station and on
Internet traffic. With DSL, the more users, the slower the system responds.
Up to 10 remote users can be supported simultaneously while maintaining
a respectable refresh rate (1 image per second).
Remote Control
Mode is used by authorized personnel and allows remote users anywhere
on the Internet to either take full control of the system or to watch
passively. The 'full control' remote user will have the capability to
pan, tilt, and zoom all while watching live video at rates of 1-4 frames
per second, depending on Internet traffic, connection speeds and resolution
of the images. When in this mode, the Web Cam Mode is temporarily suspended,
meaning that the web page imagery will not be updated until the (full
control) remote user(s) have disconnected. Web Cam mode will automatically
resume after 3 minutes of inactivity. Note that, if a weather station
is attached to the system, weather data and graphs will continue to be
updated even while a remote user is full control, effectively sharing
the Internet connection with VM95 and the remote control user. |
