GeoVision Support
1.2 This
problem comes up if the installed software drivers were wrong or
the motherboard not compatible.
-
GeoVision uses the "BT878" chip set that is used
by lots of other capture card; or video card with capture
capability. If your computer has those cards installed
previously, Windows most likely would erroneously assigned the
wrong driver to GeoVision. In that case, please re-install the
appropriate drivers from the GeoVision CD-ROM and your problem
will go away. If this does not work for you, then, follow the
next step.
-
GV800
drivers for version 2.0 hardware and version 5.2 should be:
|
There will only be three audio and three video drivers similar to
the above for GV750, two of each for GV650, one of each for GV600,
GV250, GV150.
|
|
When you look into the details of the audio and video drivers, you
should get the attached:
|
Please make sure that your audio driver is at version 2,1,0,0 (or
later) and the video version is 2,1,6,6 or later.
If you cannot get the above drivers installed, there must be some
older versions of software in your computer.
Following are steps to uninstall old drivers from your computer:
|
Delete all
GeoVision application software using "un-install".
|
|
Go to Windows
Explorer, find and delete the followings: gv*.*, agv*.* , geo*.*
and also oem*.inf, oem*.pnf. |
|
Take the
GeoVision card out; turn on the computer once without the card.
Double check if there are other video capturing devices in the
computer, especially those that usually comes with the video
card (such as ATI, Matrox...) Un-install those capture devices
and software away. |
|
Install GeoVision and turn on the computer. If you have deleted
all pertaining files, when Windows start up, it will advise you
that a new hardware is found and will ASK you where to look for
the driver. (***If the computer automatically assign a driver
for you, be very careful: that means some old files are not
erased yet, or some other BT878 related capture devices are
still in the computer, and there are chances that the computer
assigns the wrong driver for you. In that case, go back to steps
2 and 3 again. ***) Direct the computer to the GeoVision
software CD, driver folder, and make sure you point towards the
right driver, based on model no. (e.g. GV250, GV800, GV600) and
hardware version. |
(In most cases, if you buy from us after April 2002, the card will
have version 2 label on it). Verson2 drivers are:
|
GV250: GV250.inf |
|
GV600: You should have two devices for 600: one for audio using
the driver with "A" on it, one for video using the driver with
"V" on it. The drivers are GV600_4A.inf and GV600_4V.inf for 600
4 port card, GV600V2A.inf and GV600V2V.inf for other 600 cards. |
|
GV650: You should have 4 devices for 650: 2 for audio using the
driver with "A" on it, 2 for video using the driver with "V" on
it. The 4 drivers are GV650A.inf and GV650V.inf for video. |
|
GV650: You should have 4 devices for 650: 2 for audio using the
driver with "A" on it, 2 for video using the driver with "V" on
it. The 4 drivers are GV650A.inf and GV650V.inf for video. |
|
GV750: You should have 6 devices for 750: 3 for audio using the
driver with "A" on it, 3 for video using the driver with "V" on
it. The 6 drivers are GV750A.inf and GV750V.inf for video. |
|
GV800: You should have 8 devices for 800: 4 for audio using the
driver with "A" on it, 4 for video using the driver with "V" on
it. The 8 drivers are GV800_4A.inf and GV800_4V.inf for 800 4
port audio and video respectively, and GV800V2A.inf and
GV800V2V.inf for all other 800 models. |
Upon complete
installation, please go to device manager and you will find the
audio driver version being 2,1,0,0 and video driver to be 2,1,6,6.

If going through the above procedure does not
help you, then, your computer motherboard may not be compatible
with GeoVision.
