7.1 Tips 

 

Installing/uninstalling the camera 

 

•  Always use the Philips installation CD-ROM to install the correct camera drivers as 

described below. Do not connect the camera to a USB port before installing the Philips 
drivers. If you do this, Windows will try to install its own drivers, which might be less 
compatible with the camera than the Philips drivers. You must have Windows running 
and have the Windows CD-ROM to hand. 

 

•  Your USB controller should be working correctly. You can check this in the Windows 

Device Manager (Click on the My Computer icon on your desktop, right-click Properties, 
then click on the Device Manager tab). An icon with the name 'Universal serial bus 
controller' should be visible. Click on this icon and Windows will tell you if this part of your 
computer system is operating correctly. 

 

•  Uninstall the driver software by using the Add/Remove option in the Start - Settings - 

Control Panel - Software window. 

 

•  For the Windows 2000 operating system you will get a message to delete the camera 

within the Device Manager manually before you will be able to reinstall the 'ToUcam 
Drivers and Tools' by using the Setup program from the installation CD-ROM. The reason 
for this is that the InstallShield cannot remove certain registry entries. 

 

IMPORTANT NOTE : 
If the installation program asks you to place a different CD-ROM in the CD-ROM drive, 
for instance the installation CD-ROM or the Windows CD-ROM, always wait until: 

 

•  the 'busy' cursor icon (usually an hour-glass icon) has disappeared from your 

screen, and

  

•  the 'busy' LED on your CD-ROM drive extinguishes,

  

before you press the eject button on the CD-ROM drive. 

 

This prevents the appearance of a blue screen Windows error message prompting you 
to replace the last CD-ROM into the drive. 

 

Should you encounter this Windows error message, correct the blue screen error by 
replacing the CD-ROM you just removed and wait for Windows to stop reading from the 
CD-ROM. 

 

 
Camera performance and system requirements 
In VGA resolution this digital USB PC Camera provides a very large data stream that needs to be 
processed in real-time by the application you are using. Although the camera will perform 
satisfactorily on a Pentium I at the lower resolutions, we recommend a more powerful computer, 
e.g. a Pentium II with 32 MB RAM, for optimum performance at the highest resolution. We regret 
that optimum camera performance cannot be guaranteed if the computer meets only the 
minimum system requirements. 

 

 
Using more than one camera 
If two or more Philips cameras of the same type are connected to your computer, only one of 
these cameras can be used at any one time.
