Fisheye Dewarping

With Surveillance Station's built-in dewarping feature, you can view fisheye camera footage in rectilinear or panoramic views. Multiple viewing regions and dewarping types can be configured. If you want to view dewarped images using VisualStation or DS cam (Synology mobile application), you can use the native dewarping feature provided by your camera. The camera will directly output dewarped images with its own dewarping feature enabled.

Note:

Depending on camera specifications and capabilities, dewarping might not be supported on your camera.
