Synology Camera Licences: Add Channels Without Buying the Wrong Pack

A shop adds a stockroom camera and the installation suddenly asks for another licence. The recorder may be working normally: its included licences have simply been allocated. Replacing the NAS is rarely the first useful response to that message.

Three questions make the purchase clearer: does the camera work with the recorder, how many units does it require, and can the system record the full workload?

Count Available Units, Not Just Camera Bodies

Open Surveillance Station > License and note the installed and used units. Default entitlements depend on the recorder; do not assume that every physical or virtual Synology system starts with the same allowance. Virtual DSM has no default device licence.

Many ordinary IP cameras use one unit each, but some multi-lens devices and video encoders are counted by channel. Several streams from one ordinary camera do not automatically mean several licences. Identify the exact device and its supported licensing method.

Keep the camera model, the intended channels, available units and recording settings together in the same planning note. This avoids treating a channel count, a multi-camera grid and a licence count as interchangeable figures.

Worked Examples: Which Pack Fills the Gap?

For these examples, assume ordinary compatible one-unit cameras and a recorder with two unused included units. Change that starting figure to match the actual License screen.

The Synology Surveillance Device License Pack is sold in 1-, 4- and 8-channel versions. A multi-unit pack uses one key. Do not buy a large pack expecting to split its individual units into separate keys for unrelated standalone recorders.

The right decision is the smallest sensible whole-system purchase, not necessarily the smallest pack. Allow for a clearly planned extra camera, but avoid paying for speculative channels while overlooking storage or cabling.

Check Camera Exceptions by Exact Model

Licence rules are model-specific. For example, Synology BC500 and TC500 cameras do not require a separate Surveillance Device License purchase for use with Surveillance Station. This exception must not be applied to every Synology-branded camera: the current licence table lists other Synology models that use a unit.

For third-party cameras, check the precise model, firmware and integration method. An ONVIF connection can provide a usable video stream without delivering every proprietary event, audio function or camera-side AI feature. The ONVIF compatibility guide separates those questions.

A useful buying note says which stream, codec, resolution and events were checked. A broad statement that the brand is supported leaves too much room for an unpleasant surprise when commissioning.

Activate the Pack and Retain the Key

In Surveillance Station, open Main Menu > License > Add and follow the validation process. Keep the key private and retain the invoice or receipt. Do not publish a screenshot containing the full licence key when requesting help.

Normal authorisation uses Synology’s server. An isolated recorder can use the documented Surveillance Station Client or DS cam authorisation workflow through an internet-connected device. Offline operation is a deployment choice; it does not mean that inventing a key or repeatedly resetting the NAS will bypass validation.

If activation fails, keep the exact error and confirm the key, recorder identity and any previous activation. Resolve ownership or validation before purchasing a duplicate pack.

Move Purchased Licences Carefully

Purchased licences can be moved to another Synology recorder; default device licences cannot be transferred as ordinary purchased keys. A purchased key can be active on only one Synology product at a time.

If the source is accessible, securely record the key, follow the documented removal procedure and add it to the destination. If it has failed, use the manufacturer’s applicable migration or ownership-verification route. Having the key, purchase evidence and the appropriate Synology Account available makes that process more manageable.

Schedule the move around recording requirements. Moving entitlement and moving recordings are separate jobs. Retain evidence that the destination is recording and playing back correctly before retiring the old system.

Finish the Recording Plan, Not Just the Licence Purchase

After activation, check recording bitrate, retention, storage health and the recorder’s published workload guidance. More authorised cameras can increase disk writes, network traffic and decoding demand. Licence units do not supply those resources.

Use the NVR storage calculator for an initial capacity estimate, then compare it with the configured streams and actual recording growth. The 30-day storage worked examples explain continuous recording and the limits of simple averages.
