Traccar can be installed on QNAP NAS (Network-Attached Storage).
QNAP package can be found on QnapClub Repo.
It's recommended to have the QNAP web server enable, to have access to my admin page to allow user modify the Traccar config file if needed. It can be also edited in SSH or WinSCP.
QNAP package is developed by third party. For support please use QNAP forum thread.
