You should have the corporate site web page that pulls up an image from the HikVision IP camera. That camera is password protected and will only pay attention to the web site or your programming IP address. Could do live feed or update on whatever schedule you want.
It sounds like the main chef wants to hand-write the menu and doesn't want to do it any other way, and you are compensating for it.
