Monitoring breathing

Hey mumma's, I am planning to move my son into his own room this month as he turns 6 months. Up until now we haven't used any breathing wear/bands because he has been next to me so I heard his movements, coughs, sighs. I'm just wondering if any of you mumma's are using any kind of tracking equipment for your little ones who no longer sleep in the same room as you. We have swaddles with breathing bands built in but my son hates being swaddled and he is now rolling over in his sleep so don't want to use them.

I can purchase breathing bands on their own or sleeping bags with breathing bands built in which pair with the camera in the room. Just wondering if it is worth doing.

Thanks!
