Introduction to Applied VisionTM oftware
Applied Vision 4 (AV4) is a software program designed to enhance the use of
en-A-Vision digital imaging products.

computer, allowing capturing, viewing, and manipulation of both video and still images.
Applied Vision 4 is optimized for utilization in a classroom setting while remaining widely
applicable for any environment in which digital imaging is required.
Here are a few of the features built into Applied Vision:
• Cross-platform support for Windows, Mac, and Linux
• Full screen viewing
• Video recording
• Still image capture
• Multiple camera support
• Advanced image editing and analysis
• Time lapse recording
• Video rotation
• Digital zoom
• Numerous science applications including calibrated measurement
Installation
Minimum Requirements
o Windows XP SP2 or higher, Windows Vista, Windows 7
o 512MB RAM
o USB 2.0
Installation Instructions
Insert the software disc into your disc drive, and the installer will launch via AutoPlay. If
your camera requires drivers, it will choose to install these by default as well. Follow the
prompts, and at the end if you are prompted to reboot, do so. When finished, plug in
your camera; depending on the model, it may automatically install the driver in a
matter of seconds, or a "Found New Hardware" wizard may appear. If the latter, click
through the default selections to automatically install the device drivers for your camera.

Automatic Updates
Applied VisionTM4 Software has an automatic update feature that will query
en-A-Vision®for newer versions of the software. You can adjust the settings or operate
this update checker manually with options in the Help menu.
Applied VisionTM 3 oftware
Temporarily we are including, for your convenience, our previous software
Applied Vision 3 (AV3) for those who prefer its simpler functions and interface. The
installer file can be accessed by browsing the "AV3" folder on the CD and running
AV3Install.exe stored in that directory.
Mac oftware
If your camera is a model that is compatible with Mac OSX, we have included a "Mac
Software" directory on your software disc from which you can install Applied Vision 4 for
Mac OSX.
