Embodiment approach 1

[0028] The monitoring center 1 is connected with multiple front-end network points 3 through the Internet 2 . Among them, the front-end outlet 3 is responsible for on-site audio and video shooting, and the monitoring center 1 is responsible for collecting, processing and managing various data information of the front-end outlet 3, which is the information center of the back-end application software.

[0029] One or more cameras 33 are set at each front-end network point 3, and are used to convert the on-site shooting into analog video electrical signals, so as to realize analog video shooting.

[0030] Each camera 33 is connected to a digital video recorder (Digital Video Recorder, DVR for short) 32 with an encoder and a local hard disk. The DVR is responsible for storing the video at the front-end outlets and forwarding the preview data to the monitoring center 1 . The DVR encodes and compresses the audio and video signals sent by the video camera 33 to the digital hard disk ...

Embodiment approach 2

[0039] On the basis of Embodiment 1, the security monitoring video data transmission, storage and on-demand method of the present invention sets a video-on-demand storage module (Video-on-demandStorageModule, referred to as VSM) connected to the digital hard disk recording device 32 through the local area network 4 at the front-end network point 3 31. Compress, store and back up the sub-stream data transmitted by the DVR through the LAN. Wherein, the video-on-demand storage module 31 adopts dual stream technology and dynamic code rate technology, and provides remote audio and video data transmission for the monitoring center through the network while storing and backing up.

[0040] VSM is deployed in all monitoring places, and compresses and stores the sub-stream (generally in CIF format, with a stream size of 256~512kbit / s) data transmitted by DVR or DVS through the LAN. Generally, the transmission bandwidth of the local area network can reach at least 100Mbit / s in theory, a...

Embodiment approach 3

[0044] On the basis of implementation mode 1 or 2, TCP / IP network protocol is adopted, and the front-end network point 3 and monitoring center 1 platform management software are combined through a standard development interface, which has better compatibility.

[0045] In summary, the present invention can meet the requirements of simultaneous backup storage, remote real-time preview and remote playback, and provides an economical and reasonable solution for networked monitoring places such as banks, shopping malls, and buildings.

Abstract

The invention relates to a method for transmitting, storing and requesting security protecting and monitoring video data. A monitoring center is connected with a front-end website through the Internet; a VSM (Video Service Module) and a DVR (Digital Video Recorder) are arranged at the front-end website; audio / video data shot by the front-end website are coded and compressed and are stored in a local hard disk; by using the dual code stream technology and the dynamic code rate technology, the remote preview and the remote playback can be simultaneously carried out, and both the VSM and the DVR can supply the services of downloading and requesting to the monitoring center, so that the robustness of a system is strong. An economical and reasonable protecting and monitoring scheme is provided for networked monitoring sites, such as banks, shopping malls, buildings, and the like.

Description

technical field [0001] The invention relates to a security monitoring method, in particular to a security monitoring video data transmission, storage and on-demand method capable of simultaneously performing multi-channel real-time preview and playback functions. Background technique [0002] The security monitoring system is an independent and complete system composed of optical fiber, coaxial cable or microwave to transmit video signals in a closed loop, from camera to image display and recording. It can reflect the monitored object in real time, vividly and truly. It can replace manual monitoring for a long time in a harsh environment, allowing people to see all the actual situations that occur at the monitored site and record them through a video recorder. As an emerging industry that is increasingly valued by people, the security monitoring system is widely used in terms of current development. Industrial and civil security monitoring methods mainly include closed-circu...
