28181接入网关查询NVR录像文件

使用公安spvmn的调测软件测试，下发如下命令：

<?xml version="1.0"?><Query><CmdType>RecordInfo</CmdType><SN>17430</SN><DeviceID>34020000001110000001</DeviceID><StartTime>2016-05-11T19:46:17</StartTime><EndTime>2016-05-12T19:46:17</EndTime><Secrecy>0</Secrecy><Type>time</Type></Query>

为了方便我将nvr的ID改为111，按编码规则应该是118，发送上述命令后，设备返回：

设备回了一个不能识别，说明这样发送是有点问题的，NVR绑定了两个IPC，需要设置通道编码ID，查录像文件应该是按通道ID来查，而不是按NVR，不然会出错。

不是发NVR的id，而是发送通道ID，往哪里发呢，当然是往NVR的地址了，具体如下：

<?xml version="1.0"?><Query><CmdType>RecordInfo</CmdType><SN>17430</SN><DeviceID>34020000001310000004</DeviceID><StartTime>2016-05-11T19:46:17</StartTime><EndTime>2016-05-12T19:46:17</EndTime><Secrecy>0</Secrecy><Type>time</Type></Query>

设备返回：

这样就可以查到NVR的录像文件了
