GeoVision Support
1.0 GeoVision cards, if installed onto motherboards with VIA
chipsets, will generate unstable clocking problems. Therefore,
please avoid using motherboards with VIA chipsets.
Basically right now on the market, the most popular motherboards
use Intel 815 series, Intel 845 (845/845D/845E/845G) series and
Intel 850 (850/850E) series chip sets, all of them are compatible
with our GV200/250/500/600V1/600V2/650/750/800V2 cards.
DRAM is another factor that affects the performance of the card.
We suggest using SDRAM, if not, then use DDR RAM or RAMBUS RAM.
We recommend any AGP video cards that supports DirectX 8.0 and
above. The Intel 845G/845GL has on board VGA function that cannot
support overlay display mode. If you plan to install our GV-DSP
card (Real-time display card), or to use the full screen video
mode (display videos from cameras only) on the Intel 845G chipset
motherboard, then you can't see the image on screen. You can get
around to this by installing an Direct X version 8.0 and above VGA
card on the AGP slot.

Windows Platform
|
Windows 2000, XP is
preferred. Do not use with server version software. Windows 98,
ME works OK, but the captured frame rate will get reduced if
used with GV650/750/800 |
RAM type
|
For best performance,
use DDR or RAM bus memory. 128M should be sufficient. |
Motherboard
requirements
|
GV650, 750, 800
models
have 2,3,4 Bt878 "capture" chip sets on the card respectively.
In order to balance the load and to control the PCI traffic,
they use the "HINT" chip on board. This HINT chip conflicts with
motherboard having VIA chip set, therefore, do not use those
motherboards. Also, use AGP video cards that supports Direct-X
version 8. You can freely use any CPUs such as Pentium, AMD,
Celeron etc.
If you capture up to 120fps at 320x240 pixel size with 4
channels of audio, all you need would be a P3 800Mhz. However,
if you capture at 640x480, you need 4 times the CPU power.
(Cannot capture audio with this video setting.)

GV250, 600 models
have one Bt878 "capture" chip set on each card. There is no
"HINT" chip on board, therefore, you can use any mother board
with CPUs such as Pentium, AMD, Celeron etc.
If you capture up to 30fps at 320x240 pixel size video with
audio, all you need would be a P3 500Mhz. However, if you
capture at 640x480, you need 4 times the CPU speed. (Cannot
capture audio with this video setting.) |
