I am looking for software that I can put 4 cameras up on the monitor and review past video for the 4 cameras while keeping them in sync. I want to be able to follow a worker

I have been demoing milestone xprotect and it does it but I was wondering if there is another product I should demo.

right now I have a few IP cameras but I would consider starting over with new non ip cameras is the right software package came along.

Is there any other software that offers multi-camera playback?
