Communication method and system for network camera and user terminal

Abstract

The invention provides communication method of network camera and user terminal which is connected physically based on USB, and device and system. The method comprises that the network camera obtains access attribute information of user terminal and resolves connection type of the access attribute information, judges if preloaded first drive program can supports the access attribute information, if cannot, then loads second drive program corresponding to connection type of the access attribute information. The invention constructs at least two virtual paths such as virtual serial port path and virtual Ethernet path based on USB physical connection, supplements and enlarges remote access style of IP camera, enable user terminal to connect with IP camera by USB and access in close distance to IP camera.

Description

technical field [0001] The present invention relates to the technical field of external communication of IP Camera (Internet Protocol Camera), in particular to a communication method and system between an IP Camera and a user terminal. Background technique [0002] Generally speaking, IP Camera can be regarded as a combination of a camera and a computer. It can capture images and transmit them directly through a local area network, the Internet or a wireless network, so that authorized users can view and store images at local or remote locations through a standard network infrastructure based on an independent Internet Protocol (IP, Internet Protocol). and manage video data. [0003] IP Camera has its own independent IP address, can be directly connected to the network and built-in Web Server (Web Server), File Transfer Protocol (FTP, File Transfer Protocol) server, FTP client, email client, alarm management, programmability and many other smart functions. The video sign...

Problems solved by technology

[0006] Moreover, there are still many defects in accessing IP Camera through the network (web), for example, under the situation permitted by IP Camera, the user downloads some custom programs (such as : Modify the web interface script) to the IP Camera, and these operations may be unsafe through the web

This is because, in the process of operating the IP Camera through the network, it is easy to be attacked or tampered with by others, so there are certain security risks in this way

In addition, it is inconvenient to use the network access, because some IP Cameras that support USB cannot access the IP Camera through the wireless network because they do not support the wireless network (WIFI, Wireless Fidelity) interface; or some IPCameras have a WIFI interface, but Unable to access via wireless network due to network abnormality; or some IP Cameras are equipped with wired network cards, but users need to turn on the PC to access, and some even need to perform necessary configuration on the IP Camera to access
