Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. 

Applies to: All Reolink Cameras & NVRs except for cameras in the NVR kit and add-on cameras.

Here is a brief introduction to Reolink P2P Sever:

Reolink P2P Server = Main Server + Relay Server

Main Server: For all UID registers.

Relay Server: For transferring data when P2P doesn’t work.

Server Provider: Microsoft Azure and Amazon Web Server (AWS).

Server Location:

  • US: Western US, Eastern US
  • EU: Ireland
  • Asia: Singapore

Backup Server: Each location has at least 2 backup servers to guarantee that the system can work properly. Each Server can work as a backup server if any server is down.

  • UID refers to a unique identifier. A unique identifier (UID) is an identifier that is guaranteed to be unique among all identifiers used for those objects and for a specific purpose. The concept has been formalized early in Computer science and Information systems, in general associating it to an atomic data type.
Notes: If users log in to the camera with UID, then means it uses P2P technology to establish the connection.
1. The P2P server only provides transmission services and does not store any application data itself.
2. Application data security is guaranteed by the application protocol, and users need to keep their passwords safe.
3. When the P2P server is being maintained or migrated, there may be a certain lag due to the impact of the DNS cache. Usually, users can try to force the refresh by restarting the device.
4. At present, the user's device will automatically select the nearest P2P server based on the location of the network. In the future, users can choose the server by themselves (under development).
5. If the user does not want to use the P2P function, he can turn off the function by disabling the UID.
