When to Call a Professional
Contact a network technician or IT professional if you have exhausted all troubleshooting steps and the camera still shows Error 61. This may indicate a deeper network infrastructure issue such as a failing managed switch, VLAN misconfiguration, or a hardware fault within the camera itself. If the camera is under warranty, contact the camera manufacturer's support for a potential replacement. For enterprise or multi-camera Surveillance Station deployments, consult a Synology-certified partner for professional support.Frequently Asked Questions
What does Synology Error Code 61 mean?
Synology Error Code 61 means that a camera configured in Synology Surveillance Station has disconnected from the DSM system. The NAS can no longer communicate with the camera, which may be due to network loss, a changed IP address, incorrect login credentials, or the camera being powered off.
Why does my Synology camera keep disconnecting with Error 61?
Recurring Error 61 disconnections are most commonly caused by the camera's IP address changing due to DHCP reassignment. Fix this by setting a static IP address or DHCP reservation for the camera in your router so it always gets the same address. Weak or unstable network connections and PoE power issues are also common culprits.
How do I re-add a disconnected camera in Synology Surveillance Station?
Open Surveillance Station in DSM, go to IP Camera, select the disconnected camera, and click Delete. Then click Add and use the Setup Wizard to re-add the camera by entering its current IP address, username, password, and protocol. Make sure to note your recording schedule and motion detection settings before deleting, as they will be removed.
Can a firmware update fix Synology Error Code 61?
Yes, in some cases outdated camera firmware or an outdated version of Surveillance Station can cause compatibility issues that result in Error 61. Updating both the camera firmware via its own web interface and Surveillance Station via the Synology Package Center can resolve these incompatibilities.
Does Synology Error Code 61 mean I lost my recordings?
Error Code 61 itself does not delete existing recordings stored on your NAS. It only means the live camera connection has been lost, so new recordings will not be captured until the camera reconnects. Your previously recorded footage should remain intact on the NAS drives.
