Functioning as a link between video surveillance products and third-party service systems, the eSDK IVS opens Huawei video surveillance product capabilities to third-party service systems and blocks the complex underlying network and technical details of video surveillance products. This helps ISVs integrate and utilize Huawei video surveillance product capabilities quickly and conveniently. The unified user operation entry frees users from multiple systems. The integrated video and service capabilities enable relevant service systems to have easier access to video information and efficiently utilize video data to support services. The eSDK IVS will continuously expand and enhance API functions to satisfy ever-changing industry market and customer requirements.
