1、获取网络相关参数

//获取设备的网络参数
    private void getNetCfg(int iUserID) {
        HCNetSDK.NET_DVR_NETCFG_V30 m_strNetCfg = new HCNetSDK.NET_DVR_NETCFG_V30();
        m_strNetCfg.dwSize = m_strNetCfg.size();
        m_strNetCfg.write();
        Pointer pStrDeviceCfg = m_strNetCfg.getPointer();
        IntByReference pInt = new IntByReference(0);
        boolean b_GetCfg = hcNetSDK.NET_DVR_GetDVRConfig(iUserID, HCNetSDK.NET_DVR_GET_NETCFG_V30,
                0Xffffffff, pStrDeviceCfg, m_strNetCfg.dwSize, pInt);
        if (b_GetCfg == false) {
            logger.error("获取参数失败  错误码：" + hcNetSDK.NET_DVR_GetLastError());
        }
        m_strNetCfg.read();
        byte[] byMACAddr = netCfg.struEtherNet[0].byMACAddr;
            List<String> macEles = new ArrayList<>();
            for (byte macEle : byMACAddr) {
                macEles.add(String.format("%02x", macEle));
            }
            String mac = StringUtils.join(macEles, "-");
            String subnetMask = new String(netCfg.struEtherNet[0].struDVRIPMask.sIpV4).trim();
            String gateway = new String(netCfg.struGatewayIpAddr.sIpV4).trim();
            logger.info("查询到到海康设备sn：{}, mac:{}, 子网掩码：{}, 网关：{}", sn, mac, subnetMask, gateway);
    }

2、设置网络相关参数

 private void setNetCfg(int iUserID, ControllerInfo controllerInfo) {
        HCNetSDK.NET_DVR_NETCFG_V30 m_strNetCfg = new HCNetSDK.NET_DVR_NETCFG_V30();
        m_strNetCfg.dwSize = m_strNetCfg.size();
        m_strNetCfg.write();
        Pointer pStrDeviceCfg = m_strNetCfg.getPointer();
        IntByReference pInt = new IntByReference(0);
        boolean b_GetCfg = hcNetSDK.NET_DVR_GetDVRConfig(iUserID, HCNetSDK.NET_DVR_GET_NETCFG_V30,
                0Xffffffff, pStrDeviceCfg, m_strNetCfg.dwSize, pInt);
        if (b_GetCfg == false) {
            logger.error("获取参数失败  错误码：" + hcNetSDK.NET_DVR_GetLastError());
        }
        m_strNetCfg.read();

        m_strNetCfg.struEtherNet[0].struDVRIP.sIpV4 = controllerInfo.getIp().getBytes(); // ip
        m_strNetCfg.struEtherNet[0].wDVRPort = controllerInfo.getPort().shortValue(); // port
        m_strNetCfg.struEtherNet[0].struDVRIPMask.sIpV4 = controllerInfo.getSubnetMask().getBytes(); // 子网掩码
        m_strNetCfg.struGatewayIpAddr.sIpV4 = controllerInfo.getGateway().getBytes(); // 网关

        m_strNetCfg.write();
        boolean b_SetCameraParam = hcNetSDK.NET_DVR_SetDVRConfig(iUserID, HCNetSDK.NET_DVR_SET_NETCFG_V30, 1, pStrDeviceCfg, m_strNetCfg.size());
        if (!b_SetCameraParam) {
            logger.error("设置前端参数失败，错误码：" + hcNetSDK.NET_DVR_GetLastError());
        }
        m_strNetCfg.read();
        logger.info("成功设置海康设备ip：[{}]", controllerInfo.getIp());
    }
