Ok. What you need to do is first download the Camera program from the link provided, or go to
www.ifirobotics.com and find the camera. It will be in a .ZIP file so be sure to have WinZip or equivalent. Now, unzip that into a directory. Go to
www.java.com and in the upper right hand corner click the Download Now button. This will install the latest Java Runtime Environment. When it is complete, go to the directory you unzipped the files to, and double click on the icon that looks like a Wordpad Document (not text file). This will load the GUI. In order to properly use it, connect the camera via Serial, and provide it power from the PWM via a Robovation controller or your robot controller. Don't worry, you do not need to give the PWM power, it gets its power without any commands or a program being put on the controller. Now you have a working camera
The only thing to watch out for is a low battery. If your battery is getting weak, you will get vertical lines in the picture. In that case, charge/replace the battery, and you will be good to go.
Hope this helped.
