Learn more Frequently Asked Questions Are specialized cameras required for Semantic Video Search? Semantic Video Search can analyze and generate AI summaries for detection events from both Synology and third-party camera brands, providing a unified search platform across diverse hardware environments. Are specialized cameras required for Attribute Search? Attribute Search can be applied to all DVA tasks that generate people or vehicle detection results. Therefore, regardless of whether you're using Synology cameras or third-party camera brands, attribute information will be generated as long as a DVA task is configured. Does Semantic Video Search affect the DVA's 40-task capacity? Semantic Video Search operates on dedicated infrastructure independent of AI analytics, activation does not consume or reduce the allocated 40-task AI analytics capacity. Does the DVA7400 support NAS functionality found on other devices running DSM? Synology DVA series supports most features found on other Synology NAS and has access to Synology Package Center. For a comprehensive list of supported add-ons, refer to the supported package list. How many licenses do DVA7400 units come with? DVA7400 units come with 2 device licenses. As your installation grows, you can purchase additional licenses to add extra cameras and other surveillance devices. Learn more. Notes: This feature will not be available at initial release but will be enabled in a future update. Semantic Video Search operates on dedicated infrastructure independent of AI analytics, activation does not consume or reduce the allocated 40-task AI analytics capacity.
