I got a new PCI card of 4ch.

I was told the software of this card could support usb camer, mixed using with cctv camer.

I pluged the 4ch card into my pc,connected two camera and two usb camera. it worked well.

i tried to add another usb camera,but no image of the third usb camera.

i tried times,no change.

why?anybody could give me advice.

The software is probably limited to four channels...

thanks very much for your reply.

The software could support up to 24ch. I installed 4 cctv cameras, it worked well, then I installed 4cctv cameras and 2 usb cameras, it worked well too. But when i added another usb camera, there was no image of the third usb camera.

 

this time, i didn't use any cctv camera, and i removed the card from my pc. I plugged in 3 usb camera,

i lcould only get 2 image.

 

i don't know why i could not get the third usb camera image.

 

anybody have some experience?

 

thanks

Perhaps the third camera needs a different driver? Does it work on its own, if you unplug the other two?

Maybe only 2 of your USB ports work? Is this a new PC or an old one? Front or rear ports? All ports enabled in the Bios? Do the cameras come up in my computer under USB cameras? Do you see any sign of them in Device Manager? The software may only be checking 2 USB ports max also.

thanks all of u.

 

I tryed all of your mentioned.

 

my usb camera need not install driver. they are all worked on their own.

usb pots both front and back were no problem.

 

"The software may only be checking 2 USB ports max also." i need confirm this .

how about the obvious: crappy software?

Also they may have put in a limit on the number of USB drives, and it may mean paying more for additional ones.

 

Just to verify its not the 3rd camera and driver in particular, have you swapped them around?

There you go, stating the obvious again... making us all look bad.

i think this software is good at others.

it works well on CCTv cameras.

 

but olny support two usb camera.

i cut a ui ,there is 4 cctv camera image and two usb camera image.

 

that's said i can monitor 6 channels by this 4ch card. but i want to get more than 6images instead of change to a 8ch card.

Maybe your USB ports can not suply enough power for the 3 USB cameras to work at the same time.
