How Does the P2P WiFi IP Camera Work

Time:2015-10-22

Just input the device ID and password, without any network configuration, your IP camera can connect to network for remotely monitoring. How does it work?
The answer is "Peer to Peer" (P2P) technology. P2P technology can allow camera communicates with other network devices without complicated network settings.

P2P Technlogy Application in WiFi IP Security Camera

Because of limitation from network technology, IP cameras are only limited in LAN network transmission, the old existing technologies could not enable IP camera to be accessible from Internet. To solve this bottleneck, computer fields come with many new technologies including Dynamic DNS (DDNS), SIP protocol and more. But these technologies only solve part of the problem, not the fundamental problem.

DDNS allow user access the IP camera which uses dynamic IP address, but if still utilizing the traditional video streaming technologies (RTSP/RTP), the video stream still can‘t broadcast on Internet (WAN), P2P technology is the right solution.

The traditional IP camera requires user to set the correct network for properly usage of IP camera, which stops many users to use the IP cameras. Moreover, intended for remotely monitoring, user have to do port forward and DDNS setting, to achieve DDNS, the DNS server should be used, therefore user can access the IP camera and watch the live video. P2P technology can allow the IP security camera automatically penetrates your network firewall and obtain IP address itself, which means eliminate the network setting and no need to use server.

Since P2P connection may bypass your firewall, and video files are confidential for users. Many IP cameras such as Unifore‘s eRobot IP camera adopts encryption connection to secure your data transmission.
