Thanks! I have already contacted to Hik Tech support. They replied that I can distinguish them by preset names. But if I name the normal preset the same name? I don't think this method works fine.
I have a Hikvision IP Dome, and I use NET_DVR_STDXMLConfig(command: GET /ISAPI/PTZCtrl/channels/1/presets) to fetch preset list that have already setted. But the preset list contains normal presets and special presets, how can I distinguish between normal presets and system special presets? Any...
