Does Sertag electronic shelf labels system only work based on cloud server or other methods?

In order to facilitate the needs of customers in different scenarios, Sertag's electronic shelf label system can be divided into two modes: cloud platform and local server. The advantage of the cloud platform is that it is convenient for centralized management, and the situation of each area can be fully understood through remote operation. Of course, some customers are only applicable in a single environment, and it is most suitable to choose local server.
