Hi,

Answering Kazimierz question, I am running IOCs on a Linux Ubuntu 16.04 virtual machine on our server.

The cameras are being used right now and I cannot test the suggest tuning of the network and camera parameters. I will post my results as soon as I get them done.

For now, moving one of the cameras IOC to another virtual machine did the trick, but now I am interested to find out If I can make them work from a single machine. I will report back.

Thank you all for suggestions and shared info.

Hi Nilson,

 

What OS are you running Point Gray camera on? If it is Windows, then it is an intrinsic issue of the OS to run more than 1 camera, not related to network tuning, but Windows itself.

Hello community,

 

I have 3 cameras (Point Grey GigE Blackfly) that I want to use

simultaneously at a very low framerate (1fps) for BPM purposes.

 

Each camera has its own IOC and they run perfectly one at a time.

However, when running simultaneously, always 2 cameras conflict with

each other and not necessary the same two cameras. During conflict, the

IOC shows an error about frame inconsistency on both affected cameras. I

have a gigabit network port on both switch and server, and the port is

far from saturation.

 

Does anyone have experience with GigE cameras and have seem this type of

problem? Is this a protocol issue since it happens even with the

original (Flycap2) software ?

 

I appreciate any shared experience with problems with GigE cameras that

could give a hint on why this is happening.

 

Best,

 

Nilson
