About a month ago I lost my Visa Check Card at Wal Mart.Someone found it immediately and used it to purchase 2.00 worth of merchandise.I was told to file a police report and the police would go to Wal Mart,look at the video surveillance,then give me a copy of the police report.Then I take the police report to my bank showing I did not make the purchases,and the money would then be added back to my account.But someone told me that Wal Mart only keeps video surveillance for a week.Does anyone have any information on this?I want my money added back to my card.Is there anyway they can catch the person who did this?I would appreciate any information.

I am asking about the dome security cameras at wal-mart

1. How many square feet (or miles, or acres) are there, of monitored areas by security cameras at Wal Mart's corporate facilities in North America?

2. What is the average number of "security" cameras at a typical Wal Mart retail location?
