Walmart security camera obscuras are so simple to use that it is nearly impossible to keep them secure.
The security camera on the front door of Walmart stores, for example, can be easily hacked by anyone with a cellphone.
In a video posted to YouTube on Monday, the camera operator uses his cellphone to take a video that shows him approaching the front doors of two Walmart stores.
The video shows a woman opening a door and leaving with her wallet.
In a second video, the operator enters the second Walmart store, takes a selfie with the camera, and then quickly takes another selfie with a third security camera.
The cameras are meant to detect shoplifters.
Walmart has been criticized for a lack of security cameras at its stores.
In an online survey of more than 400 retailers, Walmart said it had more than 1,000 security cameras in its stores, but only about 5% were equipped with facial recognition technology.
Many security cameras rely on sensors that are small, cheap, and easy to replace.
But even those that have been properly installed are vulnerable to being hacked.
A video posted on the Walmart YouTube channel on Saturday showed security cameras that were too far apart, with no security buttons to unlock them.
The operator uses a small flashlight to shine his light through a gap between two security cameras.
The video also shows a man walking in and out of a Walmart store without his wallet, which could be used to access his account.
Another security camera is seen on a security camera in a supermarket.
This security camera camera in the grocery store is easily hacked.
In a video from a Walmart security office, the video operator points his flashlight at the camera and flashes it.
The Walmart security footage was taken at about 4:50 p.m. on March 24.
