What is a P2P IP Camera and How Does it Work? With HD P2P cameras use a smartphone download the app, scan the QR code and start viewing a live feed of the camera. Before P2P came along, cameras used to be a nightmare to setup. Setup the camera, then login to the router and setup a DDNS and open ports to allow access. P2P stands for “Peer to Peer”. It is a technology that makes it simple to link the camera with a smartphone. In camera speak, there is a UID (unique ID) assigned to each camera. When the smartphone app is opened, it pings the P2P server which in turn looks for the listed UIDs and where they are located. If the camera can be pinged, it shows as online, others are offline. Once the cameras are reached, it creates a direct connection between the app and the camera. Just like the popular Bittorent peer to peer file sharing platform. 


Advantages of P2P technology used in HD IP Cameras

P2P networks. are highly scalable. e.g. Torrent sites have millions of users worldwide. As P2P is de-centralised, i.e. services are spread out over various peers, it makes the system quite reliable. Cheap and affordable P2P streams can be used to connect with multiple devices simultaneously. P2P stream can be used to backup data to the cloud Allow secure connections between the camera and viewing client with encrypted streams Not limited or blocked by closed ports, no DDNS setup, firewalls, etc. P2P UID is installed into the camera before shipment, no further settings are required.

Traditional port forwarding based IP camera. DDNS server required. Often times unreliable / paid. Port forward or port mapping on the router is necessary to reach the device from outside the network. Firewalls need to be disabled putting your network at risk.

Peer to Peer based IP cameras. Linking to the camera can be done in a couple of minutes. QR code scanning for convenience in linking. Complete protections and privacy with encrypted video streaming As server pings the camera, its easy to know when the camera is offline or unreachable.
