The instructions are in prior posts. I can’t remember where, but just do a search for “arlo” within this thread and you will find it. Basically you need to run a Python script (sample provided called arlo-sample.py) in a cron job to grab videos out of your cameras and store in the media/ folder under video1 through video4.mp4 file names. Then just add these as video tiles where you want them. You can adjust the size using the Tile Customizer by editing the value of the width and height fields.
