I know, this job is gonna give me nightmares eventually...
5 cameras per site on average, 1 front access, 1 rear access/locker room, 1 counter/cashier, 1 kitchen, 1 parking spots. I still haven't got a full list of the camera brands or models. Local DSL is supposed to be 4Mbps in all restaurants, and is shared with POS and timekeeping software running on their network. I'm assuming the video feed will suck up most of the bandwidth, but I don't think the other software they run will suffer.
