is my camera able to handle docker?
The readme says:
Go in System -> Plain config -> search -> "Docker" disable TLS,
But I do not see the word Docker?
check docker
I am trying to follow this guide to check the cameras docker compatibility.
https://github.com/AxisCommunications/docker-acap#compatibility
ssh [email protected] 'command -v containerd >/dev/null 2>&1 && echo Compatible with Docker ACAP || echo Not compatible with Docker ACAP'
Using ssh to get in to the M3115-LVE camera produces this error:
ssh: connect to host 198.168.0.10 port 22: Connection refused
Is it possible that ssh needs to be enabled somewhere first?
https://help.axis.com/axis-os#device-access
I am able to access the camera via the web interface with the above mentioned url.
camera latency
The M3115-LVE has a max resolution of 1920x1080.
When opening a stream in the browser or through one of my C++ tester apps I see a latency of about 1 second.
http://198.168.0.10/axis-cgi/mjpg/video.cgi?resolution=1920x1080&fps=24
Even at a reduced resolution of 640x480 latency is still longer than that of a normal USB web cam.
What are the best methods to reduce the latency?
Camera and Computer are connected via a wried connection.
do the build_deploy_and_run.sh or run.sh also handle docker install?
I assume docker first will need to be installed by me on my macOS 10.15.7 system. Or is that also part of the supplied shells script?
Would these be the docker install instruction ?

‘SimpleBlobDetector’ has not been declared
Now that i can run the motion detection example i am experimenting with blob detection.
But following the C++ example here produces the below error message.
I am unsure how to test which opencv modules ACAP had installed.
