Synology NAS/NVR comes with default licenses1 that allow you to set up and manage surveillance devices. Synology also provides three options for additional purchased licenses: 1, 4 or 8 Surveillance Device License Packs; each comes with a single license key, allowing you to activate 1, 4 or 8 surveillance devices at a time.
To find out the maximum number of surveillance devices supported on each Synology NAS/NVR, please refer to the specifications of each model.
