Is my boyfriend watching me on work cameras?

My boyfriend and I work together, opposite shifts. My boyfriend has been insanely insecure over this new guy on my shifts. Mentions him pretty often and it always either turns into a fight or at least him accusing me of something. I’m pretty friendly so I try to talk to whoever talks to me and I don’t treat the new guy any different so we joke and stuff sometimes. I guess he’s also friends with the AGM (also bf’s friend) from years ago. I guess he has a crush on me and told her, according to bf. So she turned around and told my boyfriend and my boyfriend freaked out on me. But it got kind of weird because when I came into work the same night, the cameras were playing on the computer and paused on my shift. I immediately started questioning my boyfriend why and he said they were “just running” (but paused? On my shift?) and how he used them earlier to watch his shift while in the office. But that also means he also moved the time frame of the cameras because you have to click a button to change from live time to past footage. I started explaining that now I’m paranoid and uncomfortable thinking he/his friends are watching to see if I entertain this guy. He said that I shouldn’t be paranoid unless I’m doing something back when he flirts with me. But then said “don’t smile and stuff with him anymore” which I think is really odd because the new guy did come over to talk more that shift and I smile constantly out of being overly polite. So now I def feel like he/his friend are watching me and I feel so weird.
