I have a Moultrie XA-6000. I think they have a newer version out now. It uses an app that you can view from your cell phone or you can also pull it up on your desktop or laptop cornputer. No need for cameras to be linked to each other as you can view them all individually from the app or the website. I have had very good luck with mine.He wants something where all cameras will go to his phone. I just assumed (I know lol) that linking them magically was a thing. Like I said, I know very little about trail cams. It looks like the Tactacam is what he needs. Thank you for the info
