    1. Follow the [Download Here] link above and then you will see the link to the driver file.

    2. IN Rapidshare page, click Free User and you will need to wait for a moment (countdown timer). Once countdown finish, you can start download the driver.

    Thank you.

    do i needto save it on my desktop? after i download it using the rapidshare?

  • admin August 26, 2008 2:23 pm #

    Yes, and since it is a zip file, you will need to unzip it.

    Then you will find a setup.exe inside the CameraH folder.

    Run the exe to start the driver installation..

    Thank you.

    my pk635 webcam is working but the built-in mic isn’t.
    is this a driver problem?

  • admin September 14, 2008 12:23 pm #

    Hi del,
    I don’t know. I do not have a pk635 with me so I can not test it. Is the mic comes with a connector that need to be plug into the MIC IN port in your PC?

    yes it has a mic plug for the built in mic.

    After downloading file i just open the set up.exe and the installation begins. I followed the instructions but when i restart the computer, still no camera was detected.

  • kya February 21, 2009 4:23 pm #

    i have the same problem with darlyn…i followed every step and still no camera detected.i tried the a4tech website but i cant understand one of the steps…3 ) After successfully downloading the driver , do not open the driver file until you make sure the following has completed : ***REMOVE / UNINSTALL any original mouse driver from the PC . ( If you forgot to do this part , your driver may not be able to install correctly and successfully later )

    How can i uninstall the original mouse driver?
    please help me…
