IP camera access method based on P2P

Abstract

The invention relates to an IP camera access method based on peer-to-peer (P2P). A P2P technology is utilized to enable an IP camera to establish a legal session through a server. Advantages of the access method are as follows: a p2p access technology on the Internet is applied to an IP camera, so that restriction that an external network IP address can not access a multi-layer NAT internal network in the prior art is broken; therefore, video monitoring interconnection can be realized everywhere; and meanwhile, hardware costs and a network complexity are not increased.

Description

technical field [0001] The invention belongs to the field of network camera communication, in particular to a p2p-based IP camera access method. Background technique [0002] IP camera, also known as network camera, is a web server that can operate independently, integrating network and WEB service functions, and can transmit the captured video to any place through the network, as long as the user enters the IP of the IP camera on the WEB browser Address or network name, you can access the live video at any time, and you can communicate with the computer, which can be widely used in large stores, schools, and factories. [0003] The current IP camera can basically only be limited to internal network monitoring or running on a network that has an external network IP but opens a fixed port or has only one layer of NAT. If the user has broadband in the community, the Internet on the external network cannot access the IP camera if the fixed port cannot be applied for. At pre...

Problems solved by technology

[0003] The current IP camera is basically limited to internal network monitoring or running on a network with an external network IP but an open fixed port or only one layer of NAT

If the user is a residential broadband, the Internet on the external network cannot access the IP camera if it cannot apply for a fixed port
