Communication method, apparatus 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, device 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 features.

Problems solved by technology

For example, when you need to view some log information in the IP Camera system, or certain processes or programs, you cannot access it through a general platform, and it is also impossible to access it from a web page.

This is because the limitation of cost and positioning makes some IP Camera products support Universal Serial Bus (USB) interface, but does not support Universal Asynchronous Receiver Receiver (UART) interface and cannot visit IP Camera, thus resulting in IP Camera. The access is very inconvenient; or for the sake of network security, the background access under the remote login (Telnet) mode has been turned off, resulting in the lack of necessary debugging means or background control means when the IP Camera has a problem, so the only way to IP Camera return to factory for repair

[0006] And, visit IP Camera by network (web) and also have a lot of defects, for example, under the situation that IP Camera allows, the user downloads some custom programs (as: revise web interface script) on IP Camera, and these operations pass the web may be unsafe

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 IP Cameras to access
