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