三．PaaS face recognition smart device management cloud platform
       Our company provides the API interface of the PaaS face recognition notification device management cloud platform to connect with the customer's SaaS business platform to achieve cloud-to-cloud connection. The PaaS platform supports cloud or local deployment (private)

Based on our networked face lock, we have developed applications in hotels, apartments, public rental housing, dormitory management and other industries. In order to facilitate customers' business layer management software (SaaS) to connect with our face lock and other smart devices, we have specially developed a set of "Face recognition smart device management cloud platform" (hereinafter referred to as PaaS platform) that manages smart devices such as face locks. This cloud platform serves as a link between the business layer platform (application layer) and smart devices (perception layer). , the face recognition smart device management cloud platform performs reliable device management and data management of smart devices by accessing various smart terminal devices (including face door locks, face access control, etc.), and provides API interfaces and third-party services layer management software for data interaction.
