Running arv-tool-0.8 -d all gives following output:

I am able to ping to the camera with ping 169.254.0.1:

I have verified that the firewall is off with sudo ufw status:

How the camera is connected to the machine ?

[shrikadam]

Camera has an M12 connector with which it is connected to PC for data transfer (with RJ45) and to PSU for 48V power using a breakout cable. With Cognex' proprietory software (InSight Explorer), I am able to at least detect the camera and get a live feed (although that too did not detect the sensor by default; I had to manually scan the peripherals). Let me know what you think; I'll try to add an image of the setup here tomorrow.

Thank you for the reply and very much grateful for this project!

I don't know what is causing your issue. What could help is a wireshark capture of the traffic on the 169.254.0.0 interface while aravis is trying to connect to the camera.
