While Reolink cameras are perfectly compatible with Reolink NVRs, it is not recommended to add non-Reolink cameras to Reolink NVRs as compatibility cannot be guaranteed.

You can use Reolink cameras to work with Reolink NVRs.

If you still want to add the third-party camera to our NVR, please make sure that the camera supports the ONVIF protocol.

For more details, please refer to:
