The cameras make no sense

So, the 'nannycams' are motion-activate. Gotcha.

How do you have MULTIPLE motion-activated cameras connected to the same display? How?

Is there some kind of buffer server, some kind of queue system, some kind of internet-connection required or LAN network system or what? Where is the server itself, and so on...??

Usually each camera has its own dedicated display, or you can switch the cameras on one display, but that the CAMERAS THEMSELVES do the switching somehow 'automatically' based on motion - that requires quite a lot of explanation.

This is also yet another case where movie TELLS us one thing and SHOWS us a completely different thing that's nothing like the thing we were told.

Look carefully at 'motion' in front of each camera in the 'explanation' scene. The teddy cam is basically in CONSTANT MOTION, and yet its camera does not show anything on the TV most of the scene, ONLY when it's supposedly 'funny'. It's VERY random from the camera's point of view (figuratively speaking, not literally).

So how the heck is this supposed to work? What happens if and when ALL the cameras detect motion? Shouldn't the signal be 'scrambled'-looking, when all cams are trying to output their signal simultaneously to the same display device? Maybe it could 'split screen' automatically?

What CONTROLS which camera gets to show its footage, if there is more than one camera with 'motion' in front of it? None of this make ANY SENSE, unless you have some kind of queue system, which WOULD require a server, probably quite a noisy one, considering it's 2000, and some kind of expensive wireless LAN system.. then someone would have to program and maintain that server, and who decides which camera has priority, and how do you DECIDE something like that? What if you decide wrong and the burglars are not shown on the camera that would have shown your face?

The ONLY viable way of using more than one camera this way, would be not to automate it, but to have someone constantly observing and switching cameras OR possibly someone in a control room watching multiple display devices at once.

The cameras don't even work as explained, which you can easily see if you keep all this in mind while watching that scene. Greg/Gay is twirling that thing like it wants to make it motion-sick, and yet the camera does NOT show the floor at any time - it ONLY switches on when 'it's funny'.

None of these camera systems make any sense without multiple displays, some kind of automatic split-screen (which obviously doesn't happen, but if it did, it would require some kind of CPU/server system, which would be very complex and expensive with wireless LAN considering it's supposed to be some kind of viable, cheap product to keep an eye on your babysitters or whatnot..), or a dedicated server, that if it crashes, there goes your camera system.

There doesn't seem to be any information, either, which is ridiculously stupid for a system this complicated - if you have MULTIPLE CAMERAS and you are trying to keep an eye on basically anyone/anything, you should definitely have a date, time, cam number and so on printed on screen.

Look at how Tesla cams do it and think if this system is even close to as sophisticated - after all, this is about 24 years in the past, so this kind of tech would not have been available very cheaply. This scene is shot very cleverly, but I am not even sure how accurate these cam displays are anyway.

To add - isn't it a MASSIVE FLAW in the system if you can just turn one cam off by creating 'motion' in front of another? The camera switches completely to the 'Vase cam' from the 'Teddy cam', so now whatever the Teddy cam sees, is no longer shown. Anyone that knows this, could easily exploit it by keeping one cam completely blind at all times simply by 'motioning' in front of another. Does this make ANY sense??

Also, they could actually do it ACCIDENTALLY as well. Let's say there's a gang of thugs robbing the house in teddy cam spot, but one of the robbers, very early on, just happens to keep motioning near the 'vase cam'. Now the Teddy cam isn't showing anything and there's a big blind spot that the robbers can utilize without even knowing about it...

..is THIS the level of security ANY OF US would find acceptable if we lived in a big house like that and wanted to keep an eye on any motion that happens there?

I don't think so.

Which means.. this camera crap makes NO SENSE whatsoever!
