Hi Mark,

Here we go:
> - What is the approximate mean time it takes for the camera to freeze?  I would like to try to reproduce the problem and want to know how long I would need to test.
In case of Flea3 about 3 weeks. We only ran Blackfly S for a longer time once and it lasted 73 hours. I'm running it again now.

> - Have you tried running the Point Grey software, either FlyCap2 or SpinView with these cameras?  Does that also freeze?  That would tell us if it is a problem with the hardware or their library, or the EPICS software.
We have but not for longer periods of time so I can't say if it would work longer using that software.

> - Have you tried running the aravisGigE software?  That would also help to see where the problem is.
Not really, no. I gave it a quick go at the beginning and ran into some problems with the driver not finding any cameras so I then switched over to ADPintGrey.

> - Is your camera connected point-to-point with a dedicated NIC, or is it on a network with other devices?
No. The IOC is running on a VM and the camera is connected two switches away from it. It is however on its own non-routed VLAN so there shouldn't be any other traffic.

> - Have you enabled jumbo packets on the NIC?
Yes. The whole network infrastructure between the camera and VM as well as the VMs NIC has jumbo frames enabled.

> - Have you followed the recommendations in this Point Grey article for system network buffer sizes?
https://www.ptgrey.com/KB/10016
Yep.

> - Are you seeing error messages about "Image inconsistency" indicating dropped frames?
Yes. Running at 1Hz I get it roughly once every 90 seconds.

Cheers,
Andraz

Hi Mark, 

Thank you for recommendation, however, we have tried using BFLY-PGE-13S2M-CS with adSpinnaker on Ubuntu 16 and FL3-GE-13S2M-CS with adPontGrey on Centos 7 but both of them "freeze" after running smoothly for some time. They become unresponsive and an IOC reboot is required in some cases even power cycle of the camera.  We're running them at toughly 1 Hz so they should get overworked.

At this stage we're looking at potential alternatives or any kind of advice if someone has had similar experience with those cameras?

Cheers,
Andraz

Hi Andraz,

The Point Grey Blackfly cameras will meet your specifications:

https://www.ptgrey.com/blackfly-gige-poe-cameras

Here are 2 examples:

BFLY-PGE-13S2M-CS

1/3 inch, global shutter, 1288x964 pixels

3.75 micron pixels
66% QE, 11 e- read noise, 9339 e- full well
58 dB dynamic range
30 FPS
POE
$345

The following model has significantly better QE, read noise, and dynamic range in a somewhat larger format:

BFLY-PGE-23S6M-C
1/1.2" sensor, global shutter, 1920x1200 pixels
5.86 micron pixels
80% QE, 7 e- read noise, 33105 e- full well
73 dB dynamic range
41 FPS
POE
$495

Either camera can be used with 3 areaDetector drivers:

ADPointGrey (Windows, Linux RHEL 7 or higher) aravisGigE (Linux, most any version) ADSpinnaker (Windows, Linux Ubuntu 16 and higher)

Mark

Hi all,

We're looking into replacing our old Firewire cameras with Ethernet ones and we'd be interested in any suggestions and experiences you have had with different camera models.

Some requirements:

-          1/3 inch, global shutter, mono sensor at roughly 1300 x 900 resolution

-          Good quantum efficiency and low noise

-          Roughly 4 microns pixel size

-          Ethernet

-          Preferably POE

-          areaDetector support

Cheers,
