My brother does some video camera installation work, and he heard a story about one of our local casinos.
The casino uses HD video cams for surveillance. Every dealer has to stand or sit on an "X" marked on the floor, and is monitored by at least 3 cams from 3 different angles. Every player position is monitored by at least 2 cams from different angles. There are other fixed cams throughout the casino, plus various cams with remote pan/tilt/zoom that can be manually operated at will.
A common standard for HD video is 24-bit 1920x1080i60. Raw data rate is about 180MB/sec; even with a typical MPEG-2 or equivalent compression codec, it's still 12-13MB/sec.
The casino runs 24/7/365, so one HD cam will generate ( 12 MB/sec ) x ( 86,400 sec/day ) or a little over 1 terabyte ( 1TB ) per day.
Here's where it gets interesting:
- the casino has
900 cameras- they maintain
6 months' worth of dataThat's roughly ( 1TB / day / camera ) x ( 900 cameras ) x ( 180 days ), or about 162,000TB !
Apparently they maintain a 6,000TB (6PB) SAN for video storage - that would be good for about a week. Heaven knows how they store the rest of it ...
I'd guess our local casino would be pretty small compared to some of the ones in Vegas etc., too ...
