Someone said in another thread AP has to be kept unspoken in casinos because they have audio now as well as video. He even said they have professional lip readers (although I don't know why they would need that with audio)

I am quite certain they do not record audio on the gaming floors (only in quiet back rooms).

I have some experience with sound production from my days in the motion picture business both on set and in post though by no means am I a specialist in the matter

There are a number of reasons but basically its not feasible.

1) Ambient sound: Microphones are going to pick up everything and the audio from a gaming floor is nothing but a cacophony of bells, repetitive music, laughter and chatter, drink girls etc. There is no way any clear discernible conversation can be made out of that.

Yes if someone were screaming at the top of their lungs perhaps having won a jackpot you could make out what they were saying but I don't know any AP's YELLING their conversations. Most will be whispering or talking normal

2) no zooms - while video can be zoomed in to see the smallest detail there is no audio equivalent. You cannot zoom audio in closer to a conversation.

3) sound travels a short distance - unless the entire casino is miked sound simply cannot travel the distance required for proper recording. And the further away the mikes the more problem number one intrudes

4) no speed review - with thousands of floor cameras casino surveillance teams are not watching every image intently. Instead they give cursory looks at thumbnails and zoom in when necessary or they rewind if requested. Security can speed zoom through images at 2x or 3x speed or more. You can easily see if someone passes by a machine for example

There is no audio speed zoom. Well, there is but it sounds like the chipmunks on meth. Its simply unintelligible high pitched gibberish. It would literally have to be listened to in real time

Thousands of cameras with audio being reviewed in real time? Prosecutors and FBI will hire people to transcribe these types of recordings to prove a crime with a few hidden mikes. Casinos will not do it for thousands of cameras recording millions of hours of audio.

It is simply not feasible for casinos to spend all that money on miking the gaming floor for what amounts to a tiny negligible amount of usable data

I think the question is not, "can they", because they certainly can. The technology exists to place small microphones all over the place. Just look at all the video and audio recorded by those newfangled doorbells. Darkoz is certainly correct though that the quality of the recording from a general wide field microphone would be inferior in a noisy casino. However, shotgun mics and parabolic dishes can to a pretty good job ignoring the ambient noise and picking up sound at a distance.

I think the question is "why would they need audio?" If was in charge of surveillance in a casino, the ability to eavesdrop on conversations would be valuable (but maybe not legal?). In my mind, the main focus of the surveillance would be employees, not patrons.

I lost a couple of hundred dollars in bets on a craps table when my "I'm off on the next roll" statement to the dealer, that I was standing practically next to, was not heard. Even though all the other players on my end of the table backed me up, he still swept up all my place bets. I ended up calling gaming on that one, as I was pretty sure the dealer was hard of hearing.

This is how the most unknown known AP in the west does it:

Why would someone talk about AP in a casino? That stuff is best left to the back of the bus. Doesn't everyone know this?

If there is technology to do it I'm sure it's being done in some casinos. In my experience, casinos will spend a $100 to prevent someone getting over on them for a $1.

The fact is the technology to spy with audio in a casino would require directional mikes also called spot mikes or unidirectional mikes (its been awhile since audio 101 but those are the terms I remember)

Anything else is going to pu everything in the room and become unintelligible

So if the casino is going to mike the gaming floor to obtain USEFUL sound they must install thousands of mikes (since they are not psychic or prescient where any particular AP team will be standing)

That would require hundred of thousands of recorded audio surveillance.

Okay they have the audio. Now what?

There is NO TECHNOLOGY TODAY that can understand what is being said and point out useful tidbits besides the human ear. And there is no way a staff of casino workers are listening IN REAL TIME to thousands of hours of audio.

Now if they did mike the casino the ONLY way they could handle a workload would be to only concentrate on those players who they have identified already as AP's or cheats. Which means not talking AP in a casino to avoid the audio is moot.

If they are surveilling you with audio you are already flagged, tagged and marked as an AP. Your career at thst casino is effectively over

You just dont know it yet.

Security is already on the way

However for those technical reasons above I doubt they have the entire floor miked with thousands of individual units

That's because casinos believe that
every dollar you walk in with is their's,
and they will do anything to get it.

A casino is just the old traveling
carnival in a permanent location.
The old carnival would do anything
to empty your wallet. It's a traveling
con, that's why the cops were always
hard on them.

Casinos have cleaned up the con, but
you still can't beat them. And if you
find a way to, they'll hate your guts
for cheating them out of getting
your money.
