I run a retail business and I am trying to deter theft by my employees.
I have a usb camera setup pointing towards each register. The camera records and stores the video on the hard drive.
My point of sale software is a php base software that was developed in house. I would like to add a feature to my video where
when the employee scans an item, that item would show up on the video (as a video overlay) and the timed scanned would correspond with
the video. (Picture is attached for visual effect)
Does anyone have a clue where I would start? Write the data to a port? Not real sure where to go.
Any ideas would help
