Deattie 0 Posted May 2, 2013 Hello I wish to record external audio and video and have purchased a Dahua hfw-3200s because of its small size and high resolution, but it does not have audio input. The next step is to link audio from an external cctv microphone, so blueiris can combine the audio and video. What hardware do I need ? I believe the microphones are powered so deliver analogue output at line level (around 1V) to an RCA connector. Will the attached link do the job ? http://www.behringer.com/EN/Products/UCA202.aspx. When I contacted the manufacturer, they did not know because they are in the music not cctv industry. Are there any devices that can handle more than two microphones ? I’m in the UK, so wiretap laws do not apply. Thanks Deattie Share this post Link to post Share on other sites
