90 days on a DVR
There is no federal law dictating how long a US bank must keep video surveillance footage. However, banks are subject to state laws and regulations which may stipulate specific retention periods for video surveillance footage. Banks typically retain footage for a certain period to comply with legal requirements and for security purposes.
Until they need to get rid of it. Which is also why you shouldn't do anything dumb so you don't have to worry about anything.
Forever if they feel that there is something to keep. Otherwise banks keep Video surveillance for 10 years.
one year
Non-bank branded ATMs (like the ones you find in gas stations and bars) generally do not have integrated surveillance cameras, so the only surveillance footage would be what is retained by the store's general surveillance system. Stores with digital CCTV will retain 7-60 days of footage, which is enough to aid in almost all credit card fraud investigations. Bank branded ATMs (especially ones located at actual banks) generally retain at least 90 days of footage, although 365 days of retention is pretty common. Because certain types of fraud can take months to discover, it is worth it for the banks to pay the extra cost to have enough hard drives to store a year's worth of footage. As a federal agent who investigates financial crimes involving banks, I have never seen a bank retain more than two years of general surveillance footage unless they had a reason to suspect a customer or teller of fraud.

Try to keep your mouse on the target as still as you can.
That's probably a corporate secret. It can only be answered, if at all, by contacting their Security Department and asking.
Certainly, as long as students know they are there.
