Abstract

The invention discloses an intelligent network camera with fixed target protection function, which uses a single-chip DSP processor as core, provided with a video I / O interface, a voice I / O interface, a video AD / DA converter, a voice DA / AD converter, a memory, and a network communication module. The DSP processor is provided with vision analysis software. User sets a protected target, uses a video input device to collect a target image, the vision analysis soft analyzes the background information to the target image. And when the target image is all shielded, and the image changes and the target moves when the shield is returned, user uses a video output device and a network communication module to output alarm information. The invention also has fixed target protection function as well as video compression and network transmission of general network camera, which can process movement and theft alarm on fixed target set by user (as parked vehicle, picture on wall, and stored goods).

Description

technical field

[0001] The invention relates to a network video monitoring device, in particular to an intelligent network camera (Smart IP Camera) with a fixed target protection function. Background technique

[0002] As more and more video surveillance systems appear in many public places such as airports, subways, squares and supermarkets, their application scale is also showing explosive development. Under such a development trend, it is an inevitable trend in the development of video surveillance systems to change video surveillance content from visual interpretation to automatic interpretation, that is, to realize intelligent video surveillance. Network cameras are currently widely used and inexpensive network video surveillance equipment. The network cameras that realize intelligent visual analysis, that is, intelligent network cameras, are an important part of realizing intelligent video surveillance systems.

[0003] Existing network cameras generally only have dig...
