Applies to: All Reolink cameras and NVRs
Remote access can be divided into UID access and IP one.
When remotely accessing your camera by using UID, there are no designed ports for it, as the camera uses random UDP ports. So you don't need to forward ports on the router, but the router needs to allow connection via any UDP ports.
When remotely accessing your camera by using IP, you need to forward different ports in the router interface for different access forms. You may refer to this article to do this:
Specifically, there are the following six types of ports:
Media port: access via Reolink Client or Reolink App
HTTP & HTTPS port: access via a web browser (the latter port is more secure than the former one)
RTSP port: watch a live stream on the VLC player
Onvif port: access via the third party software
