LEND / DELIVER / ENTRUST are distinct device-sharing modes designed to suit different ownership models and business needs between users and installers.
SECURITY SERVICE REQUEST is initiated when a security company registers an ARC account through the Dahua official site or the DoLynk Care portal. Upon registration, the company information can be found in the "Security Company List" in DMSS and DoLynk Care. This allows users and installers to directly request services and link their devices to the provider's monitoring platform.
