从海康威视LPR相机获取车牌（仅返回最后20张车牌）如何检索更多？

Question

我想从 LPR 海康威视相机检索车牌，但 xml 文件仅返回最后 20 个车牌。有人可以帮助我正确定义 xml 参数以检索更多注册表吗？

POST URL：.../ISAPI/Traffic/channels/1/vehicleDetect/plates

发布 XML：

<?xml version="1.0" encoding="UTF-8"?>
<AfterTime version="2.0" xmlns="http://www.hikvision.com/ver20/XMLSchema">
    <picTime>2020-06-10T00:00:00Z</picTime>
</AfterTime>

XML 返回此：

<?xml version="1.0" encoding="UTF-8"?>
  <Plates version="2.0" xmlns="http://www.hikvision.com/ver20/XMLSchema">

   <Plate>
     <captureTime>20200510...</captureTime>
     <plateNumber>xxxxxxx</plateNumber>
     <picName>20200510...</picName>
     <country>xxx</country>
     <laneNo>1</laneNo>
     <direction>forward</direction>
     <matchingResult>otherlist</matchingResult>
  </Plate>

  ... + 19 ...

</Plates>
