Problems solved by technology

However, the back-end recording equipment does not always have intelligent functions. Therefore, because of the demand for intelligent functions, it is often necessary to install various intelligent auxiliary equipment in the system, which increases the complexity of the system.
In addition, since there are often a large number of monitoring front-ends, intelligent monitoring front-ends or ordinary front-ends are installed with intelligent auxiliary equipment, which has the disadvantages of high cost and difficult control
In addition, the cooperation between the intelligent front-end or intelligent auxiliary equipment and the back-end DVR is often not close enough, and the two devices need to be configured more complicatedly to make the two work together. high requirements

Embodiment Construction

[0018] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0019] Such as figure 1 Shown is a system block diagram of the present invention. Among them, the DVR module is similar to the traditional DVR function. It receives the video signal input from the outside, or obtains the video data stream through the network, compresses and records all or part of the input video according to certain rules, and plays back the specified video through the network or video output at the same time. In addition, the DVR module also receives external input control signals, such as remote control, mouse, alarm input and other signals, and outputs alarm, PTZ control and other signals at the same time. In addition to interacting with the outside, the DVR module also interacts with the internal intelligent analysis module. The DVR module will send all or part of the video directly input or decoded through the network to the...

Abstract

The invention provides a digital video recorder with an intelligent analysis function. The digital video recorder is mainly technically characterized by having the function of intelligently analyzing an input video image, besides all the functions of the conventional digital video recorder. The digital video recorder can intelligently analyze each path of video input and output notification information such as an alarm and the like on the premise of ensuring various original functions of the digital video recorder, is triggered to perform operations such as video recording, video recording stopping and the like if necessary, endowed with the intelligent analysis function and flexibly applicable, and satisfies various monitoring needs.

Description

technical field [0001] The invention belongs to the field of security monitoring, in particular to a digital video recorder with intelligent analysis function. Background technique [0002] Digital Video Recorder (hereinafter referred to as DVR), has been widely used in the field of security protection due to its large storage capacity, high definition, real-time video recording and playback. As an important role in the new generation of closed-circuit television monitoring system (CCTV), DVR has shown many advantages in practical application and is gradually replacing traditional monitoring methods. In recent years, DVR has also introduced many technologies used in practical applications, such as introducing the use of mouse and remote control, which greatly facilitates the operation of DVR, and the backup technology of USB and CDR brings great convenience to data transfer and practical. In addition, DVR has already entered the era of multi-device networking from stand-al...
