A monitoring system and monitoring method simultaneously supporting two-way audio input

Abstract

The invention provides a monitoring system for simultaneously supporting two paths of audio inputs. The monitoring system comprises a first pickup device, a second pickup device, a network camera, a network hard disk video recorder and a loudspeaker box. The network camera is connected with the first pickup device and the second pickup device through connecting lines at the audio input port of the network camera so as to receive collected audio data; the network hard disk video recorder is connected with the network camera through a switch and a network to receive video data collected by the network camera and the audio data collected by the first pickup device and the second pickup device; and the loudspeaker box is connected with the audio output port of the network hard disk video recorder through a metal connecting line. The monitoring system can realize two paths of audio inputs and independent play on the basis of not changing the design of a conventional hardware architecture, enlarge the audio monitoring range, meet the monitoring demands in special fields, and save cost. The invention also relates to a monitoring method for simultaneously supporting two paths of audio inputs.

Description

technical field [0001] The invention relates to the technical field of security monitoring, in particular to a monitoring system and a monitoring method that simultaneously support two channels of audio input. Background technique [0002] The conventional security video monitoring system is composed of cameras, hard disk video recorders and other equipment. With the development of high-definition video technology, the security monitoring system is becoming more and more high-definition and networked. Network cameras and hard disk video recorders are widely used. A conventional network camera supports one video input, one audio input and one audio output. The video image of the high-definition network camera can cover a larger and wider monitoring range, but only one audio input can only monitor the sound in a part of the area. In some special monitoring places such as bank counters, the video image of a high-definition network camera It can cover two counters, but it can o...

Problems solved by technology

The video image of the high-definition network camera can cover a larger and wider monitoring range, but only one audio input can only monitor the sound in a part of the area. In some special monitoring places such as bank counters, the video image of a high-definition network camera It can cover two counters, but it can only monitor the voice conversation of one counter. There are complete hidden dangers and loopholes. The current network camera only supports one audio input, which cannot meet the needs of special industries such as banks.

At the same time, the hard disk video recorder used for audio and video recording storage can only support the playback of one audio and video, and cannot meet the needs of special industries such as banks.
