I would assume the reason she was not caught on camera was because she said she parked her car elsewhere, and walked there.
Where the camera is located relative to the front door, it may only capture the cars in the front and not her side front door .
Also, don't most all houses have a back door?
I would think she could take the the seven + bags of evidence out the front side door and not be seen by the camera if she did not take it to where the cars were seen earlier.
In other cases, we know where the remote camera was. But for this case, I don't believe we have any idea which unit had the security camera, do we?
