you can bet vegas casinos aren't using grainy tapes, or substandard equipment. the 7-11 down the block? yeah...it's probably crap.

7-11's have very good systems as their liability is very high.
Wanna guess who has a tendency to have the worst systems? Airports.
There was an incident at Denver International Airport where somebody ran through the security line. Because they use VHS, you couldn't even tell if the person was a man or a woman.
A buddy of mine was interviewed on the local news and he showed a copy of digital video from a gas station and compared it to the grainy, VHS compy from the airport.
It made the airport look really, really bad.
However, DIA didn't have the money to upgrade from analog to digital.
