Activating Synology Surveillance Licenses Offline
Updated on September 27, 2026

Offline license activation exists because the normal path does not work in an isolated network: the NAS itself has to reach Synology’s servers to verify a key. If your Surveillance Station has no route to the Internet, you can complete the handshake from a device that does, in one of two ways.
If your Surveillance Station is working under an isolated network, you can activate surveillance license by either way below :
- Synology Surveillance Station Client ( Win/Mac )
- DS cam ( iOS/Android )
Method 1: Surveillance Station Client (Windows or Mac) #
- Connect to the Internet: On a Win/Mac, install and launch Surveillance Station Client. ( Download from Synology here. )
- Manage licenses: Log in and click the gear icon in the bottom right corner. Go to License Management and then Manage License.
- Add or delete licenses: Select Add License/Delete License. Agree to the terms and choose a server from your list. Enter the license keys and confirm.
- Go offline: Take that same computer to the isolated network where the NAS lives. The authorisation it just collected travels with the client.
- Connect and activate: Launch the client on your NAS and sign in. The licenses will automatically activate or deactivate.
Method 2: DS cam (iOS or Android) #
- Connect to the internet: On a mobile device with internet access, launch the DS cam app.
- Manage licenses: Log in and tap the menu icon in the bottom left corner. Select Offline License Validation and then Manage License > Add License/Delete License.
- Add or delete licenses: Agree to the terms and choose a server, or tap Add Server and enter details. Enter the license keys and confirm.
- Go offline: Take the phone onto the isolated network where the NAS lives. The authorisation it just collected travels with the app.
- Connect and activate: Launch the app on your NAS and sign in. The licenses will automatically activate or deactivate.
What Offline Activation Cannot Do #
- Offline license activation only covers active licenses. You can add or delete those; anything else needs the NAS online.
- Deactivated licenses can be reused for new accounts and Synology NAS.
One thing is worth ruling out before any offline procedure: what a Synology license keygen does to your NAS.
