How should i go about this?

[QuickStop]

the chinks 3 sons are all programers (surprisingly enough) and they have 6 cameras around the store...one above the register. all these cameras are recorded onto a pc with a nice little homeade program. if $200 goes missing, they will know how. and that will not be good for me. i do however know the blind spots. if i could move the entire register in front of the freezer, this could work
