use 2 GigE vision cams with laptop

[Steimers]

Hello,

I want to use the camera JAI AD 80 (GigE-Version) with a notebook. It's a 2 CCD Camera so you can see it as two cameras.

Up to now I wasn't able to find a ExpressCard with a dual GigE interface (NIC), is there one on the market?

If not I would like to use the Gigabit Ethernet interface of the laptop and a GigE Express Card to read the two data streams. I think it should be possible with LabVIEW (Version 8.6) to grab the data oh to cams over two different ethernet cards but because of the missing expirience I would ike to know if it really can work or if there are any restrictions caused by LabVIEW or the notebook (data bus etc.). If it's possible to use this way what are the specifications of the notebooks GigE Port and the GigE Express Card if have to take care about. I have heard that they shuld be able to work with jumbo pictures for example, are GigE ports of standard notebooks able to do this? (I have a little trouble to find the right because I also want to use CUDA and need the right GPU on it -on the other side ur cooperative partner really don't want to spend to much money).

Thanks a lot for your help

Independent of whether such an accessory exists, as a general rule of thumb it is best not to attempt challenging-throughput applications with laptops.

You don't mention what your intended framerate is nor what specific laptop architecture you have in mind, which are of course important factors.

Laptops are wonderfully versatile devices that pack an amazing amount of power into a small and portable space.  To achieve their small form-factor, there are typically design compromises made in terms of internal bandwidth (as you noted), disk capacity, disk speed, etc.  They are fine for prototyping, light-to-moderate demos, etc., but for production work or challenging throughput applications it's really better to work with "tower" PCs or small industrial PCs (if size/portability is important).

At the moment I think about an Asus of the G71GX Series, I still ordered a few data sheet from them because the pieces of information the open gamers market gets from these gadgets are not really helpfull enough. But well, how I've said the Laptop is not bought up to now, so if another one would be a better I could also take this. 

The Framerates of the Cameras are 30 fps.

The small industrial PC could be an alternative but the system should be used in different neurological laboratories and in operating rooms because of this an implementation in a notebook would just be great. Well it's a challenge but if there is a way I would like to try it.

I'll let others comment on any knowledge of the desired accessory card.

But since operating rooms don't typically have unclaimed flat surfaces on which to land a laptop, you'd need a cart for it anyway, so why not just go with a conventional PC on a cart such as

Viel Glück mit Ihr Projekt,

The latest idea is just to take a GigE Switch, I think that should save a lot of cpu power on the other side I don't know if it would be good for the bandwith. In the worst case I have 4x10 bits of data with 30 Hz to transmit. 

The carts are nice but with the background that I ave to travel around with the system still nt that what I whish for my.

I already took the old system with me -some Equpment, Electronics and a Tower, it wasn't really nice to carry all these things with me .

Vielen Dank Scott.
