I've managed to get a Huateng Vision camera working ok in Kinovea using the GenICam
One thing I can't get to work is adjust the ROI (Region of Interest) to increase the frame rate.
Normally if I half the V access it doubles the frame rate. In the Huateng Vision app I can set the ROI, but when I open Kinovea the camera doesn't work with the adjusted ROI. If I default the camera back to normal full resolution it works again.
The Camera Config screen for the camera in Kinovea has nothing under the drop downs for Stream Format, Image Size or Framerate- only Gain has a slider. You have to click on the Device property pages.
When you go into that screen there is no option for ROI.

The camera is a HT-SUA33GM-T1V it only 640*480 at 790fps. Yuo can go over 1000fps if you adjust the ROI.

If you see the "Device property pages" button at all it means it's not using the GenICam plugin but the DirectShow one to connect to the camera. This probably doesn't work with ROI as the stream formats in DirectShow are always full size. If you see two entries for the camera try the other one. There might be a conflict if it tries to load the camera through both at the same time usually I have to exclude the DirectShow ones by hand. I need to add more options related to this.

I can't access huateng website right now for some reason. The thing to look for is when they install the driver or runtime, if they are installing .cti files somewhere and updating the environment variable.
To verify, go to Windows settings > environment variables > and in the System variables list at the bottom there should be a GENICAM_GENTL64_PATH. Double click it and see if there is an entry for huateng software in there. It should point to a path that contains the .cti files. (All of this is standard and should be set by the vendor software).

You can also activate the debug logs from the help menu and then restart and in the logs there should be an entry when it tries to load the GenTL provider. This may be a bit cryptic you can send me the logs if you want and I'll have a look.

Thanks Joan, I'll try this today and post back here!

Hi Joan,
I tried all of that and it didn't work :-( .I downloaded the GenTL Producer (.cti) File_Windows file from here https://huatengvision.com/download/1/ but there is no installer. So I manually moved it into the Huateng Vision folder and manually created the environment variables like it shows on this website https://support.zivid.com/en/latest/sup … ssue.html. I also put a copy into the plugins/camera/GenICam folder.
I've emailed Huatend Vision support to ask if there is an official installer- no response yet.

As I can't post it here I will email you the log file. Thanks
