Abstract
The utility model provides a network camera based on an IP mode capable of carrying out bidirectional audio transmission through a network. The network camera has an external sound picker, coding of an audio signal is carried out in a G.723.1 coding mode, the external sound picker can be connected with an audio interface of a front-end network camera, a back-end earphone and a microphone can be directly connected with 3.5mm audio input/output interfaces of an NVR/WINDOWS PC host computer to realize high-precision video acquisition, H.264/MPEG-4 video coding is carried out, simultaneously, coding decompression on an audio signal and an image signal is carried out, and the audio signal and the image signal are packaged in an IP mode together, are outputted and are transmitted through the network to realize bidirectional audio transmission. The network camera capable of carrying out bidirectional audio transmission is convenient for a user to carry out bidirectional audio transmission through the network camera and further reduces manufacturing cost and maintenance cost for enterprises.
Description
Technical field
The utility model relates to web camera, especially a kind of web camera of two way audio transmission that undertaken by network based on the IP form.
Background technology
At present, known web camera is except the transmission of video function, and audio transmission is unidirectional.This just makes troubles to user and enterprise need to add independently transmission line (audio cable) when two way audio transmits.The two way audio video camera, the interface of external pick-up is provided, by external tone arm, has met the collection high clear video image, when carrying out H.264/MPEG-4 Video coding, the audio signal that also pick-up can be collected is encoded with coded system G.723.1.And by the numeral after compression coding look, audio signal is together with IP form packing, output, transmitted by network.
Summary of the invention
Goal of the invention
In order to facilitate the user to use when the needs web camera carries out the two way audio transmission, also, for enterprise reduces manufacturing cost and maintenance cost, the utility model provides a kind of web camera of two way audio transmission that undertaken by network based on the IP form.The web camera of described two way audio transmission adopts with the packing of IP form, and output, transmitted by network, facilitated the user, reduced again the cost of enterprise.
Technical solution
The utility model solves the technical scheme that its technical problem adopts: a kind of web camera of two way audio transmission that undertaken by network based on the IP form, there is external pick-up, audio signal is encoded with coded system G.723.1, the audio interface of the accessible front network video camera of described external pick-up, the rear end earphone, microphone can directly be linked into the 3.5mm audio frequency input/output interface on NVR/WINDOWS PC main frame, meeting the collection high clear video image, when carrying out H.264/MPEG-4 Video coding, audio signal and picture signal are passed through to the coding decompress(ion), with the IP form, pack together, output, by network, transmitted, thereby realize the two way audio transmission.Complete pickup by the peripheral hardware pick-up, by video camera, complete and encode and export.The audio frequency connecting terminals of pick-up is connected to the audio frequency input (audio in) of video camera, with this, carrys out the collection site audio signal.Because general applied environment is emphasized the definition of voice signal, thus adopt external pick-up (omnidirectional gathers or oriented acquisition) can cover larger monitoring scope, simultaneously prior, can bring better sound effect.Therefore in the Practical Project case, this mode is also that application is more.Video camera is looked except possessing scene, the function of audio collection, can also derive the function of two-way voice talkback, rear end NVR, WINDOWS PC host service function person's phonetic order can be sent to the front end control point by network, audio output interface (audiu out) output by the video camera backboard, complete the intercommunication of front and back end speech data with this.
Technique effect
The beneficial effects of the utility model are, when the user wants to realize the two way audio transfer function, only need access pickup the audio interface of front network video camera, the 3.5mm audio frequency input/output interface that rear end earphone, microphone can directly be linked on NVR/WINDOWS PC main frame gets final product; Enterprise's production cost and maintenance cost are all reduced greatly.
