This tab allows adding and modifying of messages to be displayed on an LED Sign within each zone.
The LED sign will request the messages to display using an API. The LED sign must therefore know the Zone ID.
Use the "Authenticate" API (/api/v1/Authenticate) to generate an authentication token using POST.
Use the "Messages" API (/api/v1/VMS/Messages) using GET to retrieve the message to display. Add "zoneId" and "messageId" as parameters to the request
The Zone ID can be found in the Cameras page.
