Yes, for standard users. You cannot run 8 cameras on a DS220+ for free.
But... You can buy a Synology DVA1622. It is more expensive upfront ($600~), but it includes 8 licenses. If you need 8 cameras: synology surveillance station license free
In that specific case, the DVA series is effectively license free.
You can run Scrypted NVR, Frigate, or Shinobi as a Docker container on your Synology NAS. These are open-source and have no camera limits. This is written in a blog/article format, balancing
Cost to you: $0 for licenses. You lose Synology’s polished mobile app (DS cam) but gain unlimited cameras.
Run Frigate in Docker on your Synology NAS (requires a NAS with Intel QuickSync or a Coral USB accelerator). Frigate is 100% free, open source, and has better object detection (person/car/cat) than Synology’s paid version. The Verdict: Is "License Free" a lie
Limitation: No timeline scrubbing as smooth as Surveillance Station. Requires learning YAML config files.
Let’s match your situation to the right solution.
| Scenario | Recommended Path | Cost | | :--- | :--- | :--- | | Home user with 2 doors | Use default 2 free licenses | $0 | | Home user with 3-4 cameras | Buy 1-2 licenses (total $50–$100) | Low cost | | Home user with 6+ cameras | Ditch Surveillance Station; use Frigate/Shinobi | $0 | | Small business (8 cameras, need alerts) | Buy licenses or upgrade to DVA series (includes 8) | Paid | | Testing / lab environment | Use 2 free licenses + external RTSP viewer | $0 |
If you are determined to stay at zero cost, here is the advanced configuration to maximize your two free licenses.
