AIO Husband had female friend over turned camera off

My husband (38 M) and myself (40/F) have been married 10 years. He has recently gotten more involved with guns and going to the shooting range. (I’m nervous around guns) He found out his female friend is also a fan of guns so he decided to ask her to go to the shooting range together. I didn’t have any issue with this but I just thought it was a little weird. A few days ago he mentioned that she would come over first to our house so he can go over some gun knowledge with her. (Why does she needs to come over first?) and they had plans to do this while I was at work. I knew about all of this ahead of time and thought it was kind of strange that he was bringing another woman into our home and just brushed it off and thought maybe I’m just being paranoid. I wish I would have told him I was uncomfortable. We have a nest camera in the living room and I can turn on and off from my phone. sometimes we leave the camera off sometimes we turn it on. I decided to make sure the camera was on today because I wanted to see her when she came over. when I got a notification on my phone that there was movement in the living room I looked at the Nest app and saw he unplugged the camera to make it go off-line. This was right before she came over because I saw her car parked in our driveway. It seems really strange that he unplugged the camera It just does not sit right with me. if he didn’t have anything to hide.I have attached our phone conversation. I texted him right after he unplugged it. He now is mad at me. I was at work the whole time so I could not call him. Please let me know if I’m going crazy. Am I in the wrong to be upset by this?
