Reply To: Automatic Lights and Videos on Shabbos

From Wolf and Itche’s above comments, I could think it would be okay to leave a video monitor running 24/7 in front of your home (i.e. so you can see who is at your door), and it would be no problem for the owner to leave it on during Shabbos and/or it would be no problem for any family member (or especially a visitor who knows it is running but had no responsibility for its operation) to walk up to the front door, putting your moving image on the screen.

Am I understanding you gentlemen correctly?
