The invention discloses an audio processing method and apparatus for a video surveillance system. The audio processing method comprises the steps that a monitoring front-end acquires first current audio in a current environment; the monitoring front-end receives second current audio from a client; and the monitoring front-end carries out mixing processing of the first current audio and the second current audio to obtain mixed audio. According to the invention, the local current audio acquired by the monitoring front-end and the current audio received from the client are subjected to mixing processing to obtain the mixed audio, so that the monitoring audio includes not only the current audio information of the monitoring front-end in the current environment but also the current audio information transmitted by the client to the monitoring front-end; and thus the monitoring audio in the monitoring video can be more comprehensive and complete, the completeness of the monitoring video in terms of evidence collection is improved and the detection rate is increased.
Description
technical field [0001] The invention relates to the field of video monitoring, in particular to an audio processing method and device for a video monitoring system. Background technique [0002] The current video surveillance system includes monitoring front-end PU, client CU, monitoring platform and video platform storage server SA and other equipment, such as figure 1 As shown, voice intercom and voice broadcast can be performed through the monitoring platform between the monitoring front-end PU and the client CU. [0003] Taking voice intercom as an example, the client CU can send a request to establish a two-way voice stream with the monitoring front-end PU. Specifically, on the one hand, the monitoring front-end PU collects audio A1 from its own pickup, and sends A1 to the monitoring platform through the monitoring platform. The client CU, after receiving the A1 sent by the monitoring front-end PU, the client CU decodes and transmits it to the audio or earphone for pla...
