What Does A Sleep Center Use So Many Cameras?

American Sleep Medicine has cameras to monitor people undergoing sleep studies. To the best of my knowledge each room has three cameras. A bullet camera with integrated IR, next to a dome camera which are both mounted opposite the bed. There is a third camera about face height at the doorway that looks similar to a flip cam. I'm sure they use at least one of these to record what you're doing in your sleep. It probably comes in handy for sleep disorders that cause sleep walking or people to fall out of bed, but I can't figure out what the other two would be used for. Can anyone who has installed at a sleep center provide some insight?

Here's a photo of the two on the ceiling:

We did some sleep study rooms at my last job, but they only used one camera per room, opposite the bed, which simply viewed the patient. I could venture a guess that one of the cameras opposite the bed here has a tighter field of view, maybe, for better detail on something, but who knows.

As for the one at the doorway, I have no idea.

Not sure in that case, but we were approached by one of these facilities in the past to see about using video analytics in the rooms. From what I recall, they wanted information on frequency and "magnitude" of patient movement during sleep. Depending on the exact study or case, they would be interested in if the patient is moving at all, moving with some regularity, or moving "violently".

My guess is at least some of those cameras are hooked to some form of a motion-detection/counting/etc. setup.

That makes sense. Do you have any thoughts on why the dome AND the bullet camera. Maybe the on the door was for staff. I was thinking access control, but then figured that a camera for access control would be on the outside, not in the room.

"Do you have any thoughts on why the dome AND the bullet camera. "

You're asking me to try and divine the logic behind some random user?

Thanks, but I think I'll pass ;)

No idea why they have multiple cameras. Could be doing some side-by-side tests, or could be that one camera has really good AMD for one application, and the other is really good at something else. I've seen/heard so many variations of kludged-together stuff that it could be anything.

One is a dummy.

And the other camera is watching the dummy cam to make sure nobody vandalizes it, because it's only rated IK3.
