Is there an Arlo Device Handler that supports imageCapture or a generic DH with it that would work for Arlo cameras?

Sure. It’s super simple. I have to do a little troubleshooting though… The Arlo(Connect) app will sometimes throw the error:

copyClipDataFromArloToSt() failed for 52M1817AA80A6; error=Failed to complete. Message was: Read timeout to vh-na01-useast1.connect.smartthings.com/34.206.102.155:8400 of 20000 ms Arlo_ClipCopy_ResponseTime=20206

When that happens, the camera doesn’t capture, but for the most part it works. Not sure if I am hitting a timeout or something I can’t control.
