Connect microphone to cctv system

Norman_Castle

I've got two cctv cameras, first is the same as this, https://www.ebay.co.uk/itm/1000TVL-Mini-Spy-Hidden-Pinhole-Camcorder-CCTV-Security-Surveillance-HD-Camera-/172769447182?var=&hash=item2839dc8d0e It works fine as a camera but how do I connect its microphone? Do I need to run an extra cable for the audio or can I connect the audio and video outputs together with a y connector and feed them through the same cable? The second camera has no microphone so I've bought one of these, https://www.ebay.co.uk/itm/255280813789?hash=item3b6fec16dd:g:IzsAAOSw7K5haHIw , again how do I connect this? I've looked online but none of the information makes sense to me.

The microphone looking at the pictures is part of the camera unit.  The white connector is the microphone so if you've connected this to a recording box there should be a white connector for that too.  Or you may be able to connect it to something takes that input - some hi-fi systems have these for example.

On the other link - same sort of thing except with the blue connector.

The white connector is the audio feed. Yellow for video, white for audio in your first link

Red appears to be the power line

What have you plugged the yellow cable into?

As was said, the blue connector is the audio out on the second unit. What do you want to connect it to? What is the existing camera connected to?

Both cameras are connected to a Swann cctv dvr. DVR8-1600. As one camera has a mic included I'd like to connect it, the other would be better with a mic hence the purchase of the above. If I run a separate feed for the audio there is only one audio input on the cctv which isn't linked to any of the cameras  so not sure how the two feeds would be separated then added to the separate camera images.

Keep audio and video line separate. They do not mix. Colours as given above.

Run audio cables for each camera/mic to your dvr and connect to audio inputs. Dvr has single audio (phono/rca)  output if needed but connector for tv too such as hdmi.

I think I've worked it out. The dvr can only have one microphone due to the single audio input which connects to camera1. It also needs its own cable.

Depending on how you want to treat it, you can either fit a switcher, so that you can connect both audio lines to the DVR, and manually choose to record one or the other, or an audio mixer, which would feed both into it. 

The only trouble with the second option is that if you get both cameras recording audio at the same time, you will get both combined on the DVR, and it may not be possible to decipher both soundtracks
