Yep, that's exactly what I use it for. Remote monitoring only.
I have worked through separation anxiety with some of mine twice now, and I'm this week embarking on the third (and hopefully final) attempt after a regression, and the camera is there for me to see real-time how they are doing. During training it allows me to sit round the corner watching, and if I see any hints of Linc becoming unsettled, I can get back in before he fully reaches his anxiety threshold, thereby keeping him calmer and not giving him a bad experience of being left.
The past few days it's also allowed me to do some absences from my new pup, to see how well he copes with short absences, and with or without being tired first (important so I know how much non-tired training I'll need to do with him to cover emergencies).
But that's it - it's not interactive beyond that. It's more about information gathering, really. It also allowed me to check on them at the end of last year, when a delightful cowardly neighbour left an anonymous note in my mailbox about my dogs barking. As far as I knew they were sleeping through - the camera told me otherwise (that was the beginning of training attempt #2). Now I'll never again not use it to check in on them regularly, at least while my two older boys are with me, to make sure things aren't going south again once I'm through this next round of training.
