Link alarm video monitoring integrated information centralized management system and control method thereof

Abstract

The invention relates to an image transmission system, in particular to a video monitoring system for alarm and a control method thereof. A link alarm video monitoring integrated information centralized management system comprises at least one user side and one control center, wherein the user side comprises an alarm mainframe and an intruding detector; the control center comprises an alarm situation management server and an alarm situation management work station; the user side also comprises a network video encoder, a relay module and at least one camera; the network video encoder comprises at least two caches; the control center also comprises a video access server, storage equipment and a video access work station which are connected by a local network; the video access server is connected with the storage equipment through a data wire; the video access work station is connected with the alarm situation management work station through a USB data wire; and the local network of the control center is connected with the network video encoder of the user side through an Internet network, a GPRS (General Packet Radio Service) network or a virtual special network.

Description

technical field [0001] The invention relates to an image transmission system, in particular to a video monitoring system for alarming and a control method thereof. Background technique [0002] A traditional networked anti-theft alarm system usually includes at least one client and a regional networked alarm control center (referred to as the control center). ), the control center includes an alarm server (such as a computer for industrial control) and an alarm management workstation used by the control center staff. The communication between the alarm host and the police management server usually relies on the public telephone network. According to needs, the client can also add an access control system, and the client and the control center can also add intercom equipment. [0003] For the basic alarm process, see figure 1 , during the "fortification" period, once someone enters the fortified area illegally, the front-end intrusion detector of the alarm system will be t...

Problems solved by technology

[0004] This system mainly has the following deficiencies: 1. Once a police situation occurs, the staff of the regional networked alarm control center must rush to the scene of the police situation to check and deal with it

2. The staff of the regional networked alarm control center cannot intuitively understand the actual situation of the scene where the alarm occurred, and cannot judge the authenticity of the alarm. It may be that it is only a false alarm after the alarm is sent out.

[0005] Although the current common video surveillance system can monitor the scene in real time, it cannot be used in combination with the traditional alarm system, and the traditional alarm system requires strong reliability, and the signal transmission is mostly used by telephone lines. At present, the common video surveillance system mostly uses VPN Or Internet network transmission, the response speed is fast, but the reliability is not as good as the telephone network, and the video is turned on after the alarm signal is received, there is already a delay, the situation at the time of the alarm or even before the alarm cannot be known, and perfect clues cannot be provided

Although the existing long-term video storage technology can see what happened before the alarm, but the real-time performance is poor, and it needs to be searched and retrieved from the memory, which delays the time for rapid response to the alarm.
