hi,

i got 60 fps in 640x480 / grayscale which is the default image configuration and the more bandwith expensive for this camera

hi jack,

i'm using a firewire 400 over RJ45 extender (from AVT) on a tour with an AVT Guppy
it's work fine with 50m cable, it should work at least until 100m but i never tried
it's not possible to use switch to increase the distance with this kind of extender

you can use certain switches with GigE but it increases latency i  think

another solution for very long distance (more than 100m) is the optical fiber
you can find some firewire over optical fiber extender

Basler made a technical report on industrial cameras interface here :

hope this helps

PS : does anybody tried an other solution (like GigE or USB<->Ethernet<->USB) with Gem when you need long distance between camera and computer ? Is it very stable ?
I could offer vnc access to a os x or ubuntu machine hooked up to either a Allied Vision Tech GigE or Firewire 800 camera.

Hello Max,

Did you ever tried that solution ?
Is it appropriate to detect very small movement and is it enough fast to be used in real time (not to much latency ?) ?

Hello Antoine,

Thanx to share your configuration and the Basler technical report, it is a useful document.
What is the resolution the framerate you get on your computer from your camera with that configuration ?

OK. I would prefer a camera with 640x480 pixels at 120 fps minimum to be more precise in the detection of very small movements.
