需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
目前，监控摄像机通常采用吸顶、吊装、墙壁安装等方式，拾音器的最佳安装位置通常在窗口柜台附近的台面、桌面、中间隔断玻璃上，连接网络摄像机和拾音器的线缆要绕行很远距离，施工布线工作量大、难度大，在已完成装修或正在使用的营业场所由于无法布线，拾音器只能就近安装在摄像机附近的天花板或墙壁上，导致拾音器与说话人距离过远，拾音效果差。
为至少部分解决现有技术中存在的上述技术问题，申请人进行了大量的调研和分析后发现，服务窗口柜台通常都使用计算机、收银机或其它局域网设备。这些设备通过8芯网线连接到网络交换机或主机，在这些场所有时会有多余的备用网线，正在使用的网线中有空闲的4578线芯，这些网线都汇聚到机房或机柜中的网络交换机上，而网络音视频监控系统的网线也通常会汇聚到同一机房中的网络交换机中。这些计算机、收银设备、网络摄像机有时会使用不同的网络交换机，有时会使用同一台网络交换机。利用10M/100M局域网8芯网线中的4578空闲线芯，能够实现从拾音器到监控摄像机的信号连接，据此，申请人研发出了本发明实施例中提供的信号分离装置、连接装置、交换机、网络录像机、监控摄像机及网络音视频监控系统。
本发明实施例提供的信号分离装置、连接装置、交换机、网络录像机、监控摄像机及网络音视频监控系统，能将两条10M/100M局域网线中4578线芯方便连接，有效将网线中的空闲的4578线芯分离出来，用于将拾音器所拾取的音频信号传输至监控摄像机，可在将拾音器安装在最佳拾音位置的基础上，不需要复杂的布线工程，就能实现拾音器与监控摄像机之间的音频信号传输，降低施工布线工作量，布线难度低，拾音效果好，适于基于局域网的网络音视频监控系统和业务(办公)系统。
图1为本发明实施例提供的信号分离装置的结构图。如图1所示，该信号分离装置包括：接口E1、接口E2、接口E3以及音频接收及信号转换适配器Q；
接口E1以及接口E3均为8芯网线接口，比如RJ-45接口等；接口E2为2芯音频信号线接口，比如RJ-11接口等。
其中，接口E1的1236线芯连接接口E3的1236线芯，接口E2的2芯信号线通过所述音频接收及信号转换适配器连接接口E3的4578线芯中的任一两个线芯，优选45线 芯或78线芯。接口E1的4578线芯空置，接口E3的4578线芯中有两个线芯空置。
值得说明的是，通过网线连接接口E1的设备，其信号可通过该接口E1的1236线芯至接口E3的1236线芯之间的路径传输，进而通过连接接口E3的网线的1236线向外输出；通过2芯信号线连接接口E2的设备，其信号可通过接口E2的2芯信号线以及接口E3的4578线芯中的两个线芯之间的路径传输，进而通过连接接口E3的网线的4578线中的两条线向外输出。E1的4578线芯不能和E和E3发生连接。
通过上述连接装置，能够将一条网线中的1236线和4578线分离出来，以便有效利用4578线进行音频信号传输。
另外，局域网数字信号传输及音频模拟信号传输的特点，不存在音频信号干扰局域网数字信号传输的风险，而局域网数字信号会对音频信号产生严重干扰，因而要采取抗干扰传输方法和降噪技术进行降噪处理。
在一个可选的实施例中，该信号分离装置也可以称为摄像机前置装置，设置在网络音视频系统的摄像机附近，接口E3连接8芯网线，8芯网线的1236线芯用于传输所述监控视频数据流，所述8芯网线的4578线芯中的两个线芯用于传输音频信号。该接口E1通过网线连接摄像机网络接口传输数据，以接收监控摄像机输出的监控视频数据流；摄像机输出的监控视频数据流利用该网线的1236线，经接口E1的1236线芯与接口E3的1236线芯之间的路径，然后通过连接接口E3的网线的1236线向外输出；该接口E2通过屏蔽线(即音频信号线)连接监控摄像机的输入接口，用于将拾音器采集送来的音频信号经音频接收及信号转换适配器转换后传输至所述监控摄像机，即将与接口E3连接的网线中的4578线中的两条线输送过来的音频信号，经音频接收及信号转换适配器变换后，经过接口E2与摄像机之间的屏蔽线传输至摄像机中，摄像机将其采集的图像信号与其接收的音频信号合成监控视频数据流。
在一个可选的实施例中，该信号分离装置中还可以设置壳体以及烟雾传感报警器，其中，各接口设置在壳体上，音频接收及信号转换适配器Q设置在所述壳体内部。
该烟雾传感报警器可通过电池进行供电。
具体地，该烟雾传感报警器包括烟雾传感器和报警器，该烟雾传感器用于感测空气中的烟雾浓度，在烟雾浓度大于预设的阈值时，通过报警器进行报警，实现了烟雾报警功能。
在一个可选的实施例中，该信号分离装置中还可以设置温度传感器以及湿度传感器，用于感测空气温度和湿度，实现功能多样化。
其中，温度传感器可采用接触式温度传感器，型号为DS18B20，或者精密铂电阻温度传感器PT100。

举例来说，假设在一个银行大厅中，拾音器设置在柜台上，摄像机设置在顶棚上，此时，若要在拾音器与摄像机之间设置一条网线，布线难度大，施工量大。
而通过本发明实施例提供的连接装置以及网络音视频监控系统，由于柜台旁边的计算机等设备的网线距离柜台上的拾音器较近，因此，可以通过设置一个如图12所示的转接装置，将拾音器通过网线或2芯音频信号线连接至接口E22，将计算机通过网线连接至接口E21，然后将现有计算机至交换机之间的网线连接到连接装置的接口E23，此时，拾音器拾取的音频信号传输至转接装置，然后经接口E3上的网线的4578线进行传输，计算机的数据通过网线传输至转接装置，然后通过接口E3上的网线的1236线进行传输。
若现有计算机至交换机之间的网线与摄像机传输数据的网线距离较近，此时，可以在两条网线之间设置如图2所示的连接装置，将摄像机传输数据的网线连接至接口E4，将计算机至交换机之间的网线连接至接口E5，计算机至交换机的数据通过接口E7输出至交换机，摄像机传输的监控视频数据流通过接口E6进行传输，而拾音器的音频信号经过接口E5的4578线芯传输至接口E4的4578线芯，进而通过接口E4至摄像机之间的网线的4578线传输至摄像机附近，在摄像机附近还需要设置一个如图1所示的连接装置，以便将4578线上的音频信号传输至摄像机的输入端口。
若计算机以及摄像机均连接至同一交换机，则只需要将交换机换成如图3或图4所示的交换机，利用交换机两个接口之间的4578通信通路，实现拾音器至摄像机之间利用4578线进行音频信号传输。
图13为本发明实施例提供的网络音视频监控系统的结构图三；如图13所示，在图11的基础上，网络通用设备200以及监控摄像机600均连接至同一交换机600，该交换机600可为如图4所示的交换机，其中，该网络通用设备侧的网线3连接至交换机的接口E9，该监控摄像机侧的线芯6连接至交换机的接口E8，在不影响网络通用设备200至交换机的数据传输以及监控摄像机600至交换模块700的数据传输的基础上，通过交换机中的两个接口之间的4578线芯通信通路，将拾音器拾取的音频信号传输至监控摄像机600，原理参见上述，在此不再赘述。
图14为本发明实施例提供的网络音视频监控系统的结构图四；如图14所示，在图11所示系统的基础上，该交换模块700a可以包括交换单元700a1以及交换单元700a2，分别用于处理对应设备的数据交换，两个交换单元完全独立，甚至其电源也可以是完全独立的。其原理参见上述，在此不再赘述。
图15为本发明实施例提供的网络音视频监控系统的结构图五。如图15所示，该网络音视频监控系统包括：两个监控摄像机1200和900、两个拾音器1000和1100、转接装置1400、信号分离装置1300以及录像机800。

拾音器1000用于拾取监控摄像机900监控图像位置对应的音频信号，拾音器1100用于拾取监控摄像机1200监控图像位置对应的音频信号，监控摄像机900距离拾音器1000较近，方便布线连接，但是，监控摄像机1200距离拾音器1100较远，不方便布线，但是，拾音器1100距离监控摄像机900距离较近。此时，拾音器1000通过网线9或2芯音频信号线连接监控摄像机900，将所采集的音频信号传输至监控摄像机900，监控摄像机900通过网线10连接至转接装置1400的一个输入端口，转接装置1400设置在摄像机900附近，拾音器1100通过网线11或2芯音频信号线连接至转接装置1400，如此就近布线施工量小、布线方便。
监控摄像机1200通过网线14以及网线15连接至信号分离装置1300，该信号分离装置1300可为如图1所示连接装置，信号分离装置1300的输出接口通过网线13连接至录像机800。
该转接装置1400可为如图12所示的转接装置，转接装置1400的输出接口通过网线12连接至录像机800。监控摄像机900输出的监控视频数据流经网线10的1236线芯传输至转接装置1400，再经网线12的1236线芯传输至录像机800的一个输入接口。
拾音器1100拾取的音频信号经过网线11的1236线芯传输至转接装置1400，然后通过网线12的4578线芯传输至录像机800的一个输入接口，通过录像机两个接口之间的4578线芯形成的通路，将网线13的4578线芯传输至信号分离装置1300，然后经过网线15传输至摄像机1200。
摄像机1200的监控视频数据流通过网线14的1236线芯传输至信号分离装置1300，然后经过网线13的1236线芯传输至录像机800。
通过采用上述网络音视频监控系统，能够实现就近布线，不需要复杂的布线工程，极大减少了布线的难度以及施工量，拾音效果好，促进了网络音视频监控系统的普及。
值得说明的是，本发明实施例中，各接口的线芯也可以采用连接端子替换，达到的技术效果相同。
另外，常规拾音器是一个单独设备，其信号可以直接输出到摄像机。可将拾音器的信号采用抗干扰传输(实际是电流信号而不是电压信号)，在接收端将电流信号再变回电压信号，以保证不受干扰产生噪声，或噪声很小
