Zkemkeeper.dll 支持哪些生物识别设备？

Question

我正在使用生物识别设备（考勤设备）使用 zkemkeeper.dll

从中获取所有出勤

我成功地从 essl 生物识别设备获取考勤，但是当我尝试从实时生物识别设备获取考勤时，我无法获取。

请向我推荐设备支持列表 zkemkeeper.dll。

代码在这里 -

public zkemkeeper.CZKEM axCZKEM1 = new zkemkeeper.CZKEM();
private void btnconnect_Click(object sender, EventArgs e)
{
    try
    {
        bool bIsConnected = axCZKEM1.Connect_Net(ip_address_of_your_machine, 4370);   // 4370 is port no of attendance machine
        if (bIsConnected == true)
        {
         MessageBox.Show("Device Connected Successfully");
        }
        else
        {
        MessageBox.Show("Device Not Connect");
        }
    }

    Catch( (Exception ex)
    {
        MessageBox.Show(ex.Message.ToString());
    }
}
