Conversations that have never happened:
Architect: "You know what this building needs? An EVEN MORE complex, expensive, and inefficient elevator system!"
Skyrise Property Manager: "OMG Yes!"

wow. How do you get power to the elevator cab?
Maybe its got a few electric motors and you charge it all night - the Tesla of elevator cabs!
You would install the camera in the usual way, it´s still an elevator car.
I would believe that both power and communications/control are taken from the rails, the video mentions linear technology, see http://en.wikipedia.org/wiki/Linear_motor
You could base communications on leaky coax, see http://en.wikipedia.org/wiki/Leaky_feeder
This is currently in use in subway systems, its a two-way wireless link
I know it will probably make me the oddball here but I think it's brilliant and fifty years overdue. And just as Elon Musk's hyper-loop is light years of efficiency ahead of MagLev train technology, this concept seems to me to have the same approach of radically innovative simplicity. I suspect we'll probably see the first iterations of this pop up in some new mega-building in the middle easy within a few years. Just like i'm sure that since Elon open-sourced the design for the hyper-loop, the first working model we'll see won't be in the US. (Not enough boondoggle associated with it for our US project awarding systems. :)
These elevators will no doubt be heavily dependant on network communications (PLCs, Emergency phone, locator devices, power, etc). I can't imagine that there would not be a "spare port" for cameras. I would bet that installing cameras will be simple in an elevator like this. Maybe you wont even have to pay for an elevator tec to shadow your every move (Not!).

I agree initially it looks like it would get power from the rails, like subways. The camera would be powered off the elevator's power system, then just wirelessly connected to a building wide WLAN infrastructure using roaming hand off from one AP to the next nearby AP that comes up.

I still belive wifi can make things realistic by proper placement of switches and bridges in place..
It's not clear if this thing exists beyond just an idea at this point.
But to answer your question, you'd carry video signals using essentially the same mechanism that is required for the in-car emergency phone system.
My guess is that the creators of this elevator would be well aware of the need for in-car video in at least some of the installs and have accounted for this. If not, they've probably also missed a thousand other details that would be the elevator unrealistic.
This is either a solved problem, or a problem that will never exist...
1. Sell them several virtual cameras, powered by gravity pumps (good in elevators).
2. Tell them you'll install it remotely, or with robots from the future
3. Cash check and leave town forever.
Consult the Star Trek starship design team and see how they implemented it. Those United Federation of Planets engineers are all tops in their field, and they've been doing vertical/horizontal elevators since 1966.
You could use wireless, it's just going to take multiple handoffs. Fluidmesh's Fluidity product could probably do it.
Full disclosure - I used to work for Fluidmesh, and I still like those guys....
I thought they were already doing wireless cameras in the 40,000 mile high elevators in the middle east or asia.
To answer the initial question, I assume this will run on scandalously insecure bluetooth or zigbee or some new insecure wireless scheme pushed by the elevator industy.
I would have thought you could bath the tunnels in 802.11-something and handled handoff. they can do wireless handoff on speeding trains, presumably these boxes don't take corners that fast. You need wireless in the elevators anyway to track everybody, er, provide network services to everybody who has a smartphone.
Hello everybody, this is Cosimo and I am Fluidmesh Co-Founder and VP Sales. This is a very interesting problem and I wanted to share some insight on how we have been using wireless to deliver connectivity to moving vehicles as I belive it could be of interest to some of you.
First off, we have done quite a few traditional elevator communication systems in the last couple of years using 5 GHz 2x2 MIMO technology. RF propagation works quite well inside the elevator shaft and we have seen throughputs anywhere between 50 to 95 Mbps on these systems so fully capable of supporting video, voice and data. Although I am not an expert in the elevator business, it seems that going wireless is the best way to go in case you are doing a retrofit of an existing elevator to add IP connectivity. Most of the time is a two radio set up but you need to make sure that you pick a radio that is able to handle the continously changing RF conditions and adjust modulation accordingly. With some elevators traveling north of 10mph you need to have a pretty dynamic rate controller to maintain throughput. Your traditional 802.11 AP most likely won't cut it.
In case we have an elevator that moves in two or three dimensions, we would use what is known as wireless 'trackside' technology. This is the same technology we are using to deliver connectivity to subways or industrial vehicles in a tunnel. The system is composed by three main parts: an on-board radio, a trackside infrastructure with radios spacing anywhere between few hunderd feet to 3 miles along the track/path (depending on the topology of the track), and a backbone network to connect the trackside radios to the NOC. The radios uses a proprietary MPLS-based fast roaming solution that can handle the handoff without any interruption in service and no packets dropped. We call this technology Fluidity. Currently we are rolling out Fluidity with a number of transit agencies in North America and in Europe and we are able to deliver around 100 Mbps up to 220 mph. Video surveillance and on-board passengers wi-fi are driving most of the need for on-board connectivity together with on-board diagnostics and signaling/CBTC.
With cameras being installed in the majority of vehicles, we feel that vehicle (V2V and V2I) communication is going to play a key role in the video surveillance industry in the coming years. We are excited to be able to serve those customers, drive innovation in the market, and help integrators stay ahead of the curve.
Hope this helps! I will be glad to dive deeper in some of the concepts behind this technology if needed.
As mentioned earlier, the elevator has to have an emergency phone (at least in North America anyway) which would be equally challenged by not having a traditional travel cable.
I find it hard to believe that the guys who designed the "Wonkavator" didn't devise a communication method given that you can't get occupancy without a monitored elevator phone. It's therefore a reasonable assumption that the commuication link is IP based and therefore the video link would use the same medium. The camera power would come from the elevator cab pretty much the same way in which it does currently.
I am curious to see how the trunk slammer weasels will try to cheat on these as they usually try to sneak a cable down the shaft to avoid drilling and fire stopping and all that other fun (and legal) stuff.
It would be tough getting it past the Elevator inspector in my experience. Also, why not use a simple coaxial to IP converter (assuming they have a coax cable? That one from Altronics looks pretty good (and cheap)
