The new Popular Mechanics issue (Jan 2010) has an article about casino surveillance. Obviously nothing tremendously valuable, but a few interesting tidbits.
Some of them:
Mirage's database for correlating players and dealers
License plate scanners (self park and valet)
Barona's TableEye21, "coming soon" to Vegas
RFID Chips
Mindplay as "no longer in use"
