Using static IP for connecting remote devices is costly. If your device supports PUSH technology, it is better to install WDMS server. You can configure the cloud server details in ADMS setting in the time attendance device. So even if the device IP changes, it is not a problem, the data is pushed from the device to the WDMS server. We can then add the WDMS as a device in Lenvica HRMS. WDMS has all kinds of location and time based Access Control settings and Lenvica HRMS has the Attendance reports and also Payroll module to process Salary based on the attendance.
