Hi
I have just tried your trial version with my Astro photography gear and found everything works except my usb3.0 camera. It connects correctly but errors when I try to take an image. I’m guessing that the camera may be too fast for my VH server.
Do you know of a fix fir this.
I’m running the VH server on a RPi4 in 64 bit mode. Client is on a Win10 64 bit. 2.4Ghz network.
Thanks in anticipation.

Can you see here https://www.flir.com.au/support-center/iis/machine-vision/application-n… for instructions on how to increase the usbfs memory buffer on your pi4 and see if that resolves the issue. Let me know

i’ve done some more testing today and found:
Increasing the usb buffer did not have any noticeable impact. Changing to 32bit - no difference. Changing from usb 3.0 to 2.0 - no difference. The camera is 1.2M pixels at 12 bit max.
My camera errors at any image taken faster than 0.5 seconds. If I set it to loop at 2 seconds, it runs ok for about 1 minute. My other camera is a DSLR Canon which is 10 M pixels at 12 bits and works ok but mechanical so there is a delay after each image is taken. The usb 3.0 cam is a zwo asi120mc which has fast memory and designed to run for hours at about 1 or 2 second exposures.
I’ve not tried installing your cloud server.
Have you any other suggestions to try.

Dont use wifi, use ethernet if you can.
Wi-Fi
I’m running my PC as a hotspot through a 200mbs @ 2.5Mhz dongle within 1m of the Rpi.
Will give it a go.

Yes the fast camera works ok over Ethernet.
I’m guessing your going to suggest using a faster Wi-Fi connection?
.
Yes :) But i think you should keep using ethernet
Doh
A wired, wireless system - why didn’t I think of that :(
.
:) I think the issue is the wifi on the pi is just not suitable for transmitting the images from your camera in a speedy fashion.
This is why ethernet works, i suspect that since wifi is so slow it just backs up the data transmission since you are taking a picture every second and just overflows the transmission and/or camera buffer because it cant send the data fast enough.
