Maybes you need to put up a second camera up high over the camera they stole the card out of . You know just rig it on a downward angle. Ill bet u they won't look up to see it .
I've done this before. After I showed up to a plot one day and someone had done donuts all in it, they left behind their Adele cd too.( what kind of person does donuts in greenfields and listens to Adele while doing it?) Didnt end up catching any people cept mr. green jeans.
